Emoji faces, which are ubiquitous in our everyday communication, are thought to resemble human faces and aid emotional communication. Yet, few studies examine whether emojis are perceived as a particular emotion and whether that perception changes based on rendering differences across electronic platforms. The current paper draws upon emotion theory to evaluate whether emoji faces depict anatomical differences that are proposed to differentiate human depictions of emotion. We modified the existing Facial Action Coding System to apply to emoji faces. (...) An equivalent “emoji FACS” rubric allowed us to evaluate two important questions: First, Anatomically, does the same emoji face “look” the same across platforms and versions? Second, Do emoji faces perceived as a particular emotion category resemble the proposed human facial expression for that emotion? To answer these questions, we compared the anatomically based codes for 31 emoji faces across three platforms and two version updates. We then compared those codes to the proposed human facial expression prototype for the emotion perceived within the emoji face. Overall, emoji faces across platforms and versions were not anatomically equivalent. Moreover, the majority of emoji faces did not conform to human facial expressions for an emotion, although the basic anatomical codes were shared among human and emoji faces. Some emotion categories were better predicted by the assortment of anatomical codes than others, with some individual differences among platforms. We discuss theories of emotion that help explain how emoji faces are perceived as an emotion, even when anatomical differences are not always consistent or specific to an emotion. (shrink)

‘Plastinates’ (i.e. corpses conserved through plastics) are lab created artifacts which since the nineties have been the subject of a cultural field experiment via an anatomical exhibition. Similarly to brain-dead or digitalized bodies, they constitute an ambiguous form of post-mortem existence. The article inquires after the ways in which the ontological status of these entities is constituted through the practices of body donors, anatomists and visitors. Plastinates owe their ambiguity to an oscillation between two different frames of perception. Their (...) meaning is determined by the extent to which an anatomy exhibition can impose a ‘medical gaze’ over a non-professional way of perception, which would stubbornly associate bodies with persons. This association depends on two qualities of plastinates, which refer back to the donor: on the one hand, they draw the observer into a communicational relationship, since the body is the archetypal medium of the self-representation of persons. On the other hand, the plastinated body, considered as ‘bequest’, acquires a biographical dimension: though the exhibition tries to appropriate the individual body anatomically, as an exemplar of a timeless, abstract idea of the human, the visitor’s mundane perspective reintegrates the exhibit into history. Plastinates are the embodied expression of the last will of those people whom the public meets in the exhibition. (shrink)

The present trend toward routine inquiry appears to be based on the false premise that the individual's wishes cannot be known and that, therefore, the family is the only alternative for making donation decisions. The UAGA states that the family should be turned to only when the wishes of the individual are not known.To protect the right of individuals to make their own decision, an effective and efficient process for making the wishes of individuals known should be devised and the (...) UAGA amended accordingly. I have presented the policy of strong required request as the best way to effectively protect the rights that the UAGA ostensibly gives to the individual. This policy ensures that the individual's wishes, both for and against donation, are known. It also alleviates some of the problems in the original approach that hindered the procurement of organs from willing donors. Strong required request saves families from making critical decisions, which may be painful and conflicted for some, at a time of emotional shock and grief. (shrink)

Previously conducted structural magnetic resonance imaging (MRI) studies on the neuroanatomical correlates of mathematical abilities and competencies have a number of methodological limitations. Besides small sample sizes, the majority of these studies have employed voxel-based morphometry (VBM) – a method that, although it is easily to implement, has some major drawbacks. Taking this into account, the current study is the first to investigate in a large sample of typically developed adults the associations between mathematical abilities and variations in brain surface (...) structure by using surface-based morphometry (SBM). SBM is a method that also allows the investigation of brain morphometry by avoiding the pitfalls of VBM. Eighty-nine young adults were tested with a large battery of psychometric tests to measure mathematical competencies in four different areas: (1) simple arithmetic, (2) complex arithmetic, (3) higher-order mathematics and (4) numerical intelligence. In addition, we asked participants for their mathematics grade of their final school exam. Inside the MRI scanner, we collected high-resolution T1-weighted anatomical images from each subject. SBM analyses were performed with the computational anatomy toolbox (CAT12) and indices for cortical thickness, for cortical surface complexity, for gyrification and for sulcal depth were calculated. Further analyses revealed associations between (1) the cortical surface complexity of the right superior temporal gyrus and numerical intelligence, (2) the depth of the right central sulcus and adults’ ability to solve complex arithmetic problems and (3) the depth of the left parieto-occipital sulcus and adults’ higher-order mathematics competence. Interestingly, no relationships with previously reported brain regions were observed, thus, suggesting the importance of similar research to confirm the role of the brain regions found in this study.

Plato‘s often-quoted statement in the Phaedrus that we should 'cut up each kind according to its species along its natural joints' (265e) has been an influential metaphor in discussions of natural kinds. In this essay, I investigate the source domain of the metaphor, the joints of the animal body, to determine whether, as users of the metaphor often assume, there is just one scientifically legitimate division of the body into component skeletal parts. Through an examination of animal joints from the (...) perspective of both the butcher and then the biologist, I argue that there are multiple, legitimate divisions. Yet I suggest that, properly interpreted, the deeper message of the metaphor may still be defensible: the suggestion that some 'carvings' are more natural or real than others. I conclude by considering the implications this result should have for our approach to natural kinds and for the metaphors we use to describe them. (shrink)

Autism has been defined as a disorder of social cognition, interaction and communication where ritualistic, repetitive behaviors are commonly observed. But how should we understand the behavioral and cognitive differences that have been the main focus of so much autism research? Can high-level cognitive processes and behaviors be identified as the core issues people with autism face, or do these characteristics perhaps often rather reflect individual attempts to cope with underlying physiological issues? Much research presented in this volume will point (...) to the latter possibility, i.e. that people on the autism spectrum cope with issues at much lower physiological levels pertaining not only to Central Nervous Systems (CNS) function, but also to peripheral and autonomic systems (PNS, ANS) (Torres, Brincker, et al. 2013). The question that we pursue in this chapter is what might be fruitful ways of gaining objective measures of the large-scale systemic and heterogeneous effects of early atypical neurodevelopment; how to track their evolution over time and how to identify critical changes along the continuum of human development and aging. We suggest that the study of movement variability—very broadly conceived as including all minute fluctuations in bodily rhythms and their rates of change over time (coined micro-movements (Figure 1A-B) (Torres, Brincker, et al. 2013))—offers a uniquely valuable and entirely objectively quantifiable lens to better assess, understand and track not only autism but cognitive development and degeneration in general. This chapter presents the rationale firstly behind this focus on micro-movements and secondly behind the choice of specific kinds of data collection and statistical metrics as tools of analysis (Figure 1C). In brief the proposal is that the micro-movements (defined in Part I – Chapter 1), obtained using various time scales applied to different physiological data-types (Figure 1), contain information about layered influences and temporal adaptations, transformations and integrations across anatomically semi-independent subsystems that crosstalk and interact. Further, the notion of sensorimotor re-afference is used to highlight the fact that these layered micro-motions are sensed and that this sensory feedback plays a crucial role in the generation and control of movements in the first place. In other words, the measurements of various motoric and rhythmic variations provide an access point not only to the “motor systems”, but also access to much broader central and peripheral sensorimotor and regulatory systems. Lastly, we posit that this new lens can also be used to capture influences from systems of multiple entry points or collaborative control and regulation, such as those that emerge during dyadic social interactions.

The visible human body is composed of flesh and bones for the most part, yet an invisible orchestra of sensations and perceptions creates a virtual or phantom body that behaves like a shadow following every movement and gesture of its anatomical complement. This shadow becomes only “visible” to the individual when bodily integrity is affected, anatomically or cognitively. Phantom limbs have been known for a long time. They refer to the felt presence of a missing hand, leg, or other (...) body part as if it was still in place. Reciprocally and of a supposedly cognitive origin, phantom extremities are reported by some patients that feel the virtual presence of a supernumerary limb – signifying anatomical “overcompleteness.” However, other patients feel as one of their limbs does not belong to their body – signifying “foreignness”. Various shades of the so-called body integrity identity disorder exemplify the assumed complex signification processes within the human body. The Peircean theory of signs and the Uexküllian concept of endosemiosis are combined to approach the still poorly understood phantom phenomena in light of representation and embodiment. (shrink)

Hundreds of thousands of individuals experience traumatic injuries each year. Some are mild to moderate in nature and patients experience full functional recovery and little change to their physical appearance. Others result in enduring, if not permanent, changes in physical functioning and appearance. Reconstructive plastic surgical procedures are viable treatments options for many patients who have experienced the spectrum of traumatic injuries. The goal of these procedures is to restore physical functioning and reduce the psychosocial burden of living with an (...) appearance that may be viewed negatively by the patient or by others. Even after receipt of reconstructive procedures, many patients are left with residual disfigurement. In some, disability and disfigurement may be so profound that individuals are candidates for vascularized composite allotransplantation procedures, i.e., the transplantation of a vascularized human body part containing multiple tissue types as an anatomical and/or structural unit. This narrative review paper summarizes the literature on the psychosocial burden experienced by those who have visible disfigurement. While many of these individuals experience stigma and discrimination, relatively few studies have employed a stigma framework to understand the psychosocial sequelea. This paper briefly addresses this framework. Last, particular focus is given to the psychosocial issues of individuals with particularly severe injuries who are potential candidates for VCA procedures. (shrink)

Dual functional brain asymmetry refers to the notion that in most individuals the left cerebral hemisphere is specialized for language functions, whereas the right cerebral hemisphere is more important than the left for the perception, construction, and recall of stimuli that are difficult to verbalize. In the last twenty years there have been scattered reports of sex differences in degree of hemispheric specialization. This review provides a critical framework within which two related topics are discussed: Do meaningful sex differences in (...) verbal or spatial cerebral lateralization exist? and, if so, Is the brain of one sex more symmetrically organized than the other? Data gathered on right-handed adults are examined from clinical studies of patients with unilateral brain lesions; from dichotic listening, tachistoscopic, and sensorimotor studies of functional asymmetries in non-brain-damaged subjects; from anatomical and electrophysiological investigations, as well as from the developmental literature. Retrospective and descriptive findings predominate over prospective and experimental methodologies. Nevertheless, there is an impressive accummulation of evidence suggesting that the male brain may be more asymmetrically organized than the female brain, both for verbal and nonverbal functions. These trends are rarely found in childhood but are often significant in the mature organism. (shrink)

Fodor and LePore's reconstruction of the semantic holism debate in terms of "atomism" and "anatomism" is inadequate: it fails to highlight the important issue of how intentional contents are individuated, and excludes or obscures several possible positions on the metaphysics of content. One such position, "weak sociabilism" is important because it addresses concerns of Fodor and LePore's molecularist critics about conditions for possession of concepts, without abandoning atomism about content individuation. Properties like DEMOCRACY may be "theoretical" in the following (...) sense: only devices capable of inference can come to be selectively sensitive to such properties. Thus, such concepts cannot be punctate, although their contents are individuated, as atomism requires, independently of their conceptual connections. (shrink)

Holobionts are multicellular eukaryotes with multiple species of persistent symbionts. They are not individuals in the genetic sense— composed of and regulated by the same genome—but they are anatomical, physiological, developmental, immunological, and evolutionary units, evolved from a shared relationship between different species. We argue that many of the interactions between human and microbiota symbionts and the reproductive process of a new holobiont are best understood as instances of reciprocal scaffolding of developmental processes and mutual construction of developmental, ecological, (...) and evolutionary niches. Our examples show that mother, fetus, and different symbiotic microbial communities induce or constitute conditions for the development and reproduction of one another. These include the direct induction of maternal or fetus physiological changes, the restructuring of ecological relations between communities, and evolutionary selection against undesirable competitors. The mutual scaffolding and niche constructing processes start early—prior to amniotic rupture. We are evolutionarily, physiologically, and developmentally integrated holobiont systems, strung together through mutual reliance and mutual construction. Bringing the processes of niche construction and developmental scaffolding together to interpret holobiont birth conceptually scaffolds two new directions for research: in niche construction, identifying the evolutionary implications of organisms actively constructing multiple overlapping niches and scaffolds, and in Evolutionary Developmental Biology, characterizing evolutionary and ecological processes as developmental causes.

There is considerable evidence that the hippocampal system contributes both to the temporary maintenance of memories and to the processing of a particular type of memory representation. The findings on amnesia suggest that these two distinguishing features of hippocampal memory processing are orthogonal. Together with anatomical and physiological data, the neuropsychological findings support a model of cortico-hippocampal interactions in which the temporal and representational properties of hippocampal memory processing are mediated separately. We propose that neocortical association areas maintain shortterm (...) memories for specific items and events prior to hippocampal processing as well as providing the final repositories of long-term memory. The parahippocampal region supports intermediate-term storage of individual items, and the hippocampal formation itself mediates an organization of memories according to relevant relationships among items. Hippocampal-cortical interactions produce strong and persistent memories for events, including their constituent elements and the relationships among them, and a capacity to express memories flexibly across a wide range of circumstances.

Biological science does not try to distinguish between health and disease. Biology is concerned with the interaction between living organisms and their environment. What we call health or disease is quite irrelevant.These reactions between the individual and his environment are complex. The individual and his surroundings form an integrated system which we can arbitrarily divide into two parts. There is an “external” component, by which we mean such factors as light, heat, percentage of oxygen in the air, quantity of minerals (...) or vitamins in food, micro-organisms in food or air, and so on. These can induce changes in what we arbitrarily call the “internal” component. Here we include such crude factors as anatomical structures, or finer details like composition of intercellular fluid, or secretions of glands, or changes of electrical potential in nerve or muscle.

After we die, our persona may live on in the minds of the people we know well. Two essential elements of this process are mourning and acts of commemoration. These behaviors extend well beyond grief and must be cultivated deliberately by the survivors of the deceased individual. Those who are left behind have many ways of maintaining connections with their deceased, such as burials in places where the living are likely to return and visit. In this way, culturally defined places (...) often serve as metaphors of social association and shared experience. Humans are the only kind of animal that buries their dead, and this gesture is preserved in Paleolithic sites as early as 120,000 years ago. Though not the only method of honoring the dead in human cultures, the emergence of burial traditions in the Middle Paleolithic implies that both Neandertals and early anatomically modern humans had already begun to conceive of the individual as unique and irreplaceable. Claims of primitive mortuary behavior in earlier periods than the Middle Paleolithic fall short in that they lack any signs of positive social-spatial associations between the deceased and survivors. The archaeological evidence for burial behavior in the Middle Paleolithic provides the first clear translation of mourning into a stereotypical action. These burials therefore may represent the first ritualized bridge between the living and the deceased in human evolutionary history. (shrink)

Comparative biological morphology, incorporating the study of active reaction, is contrasted with genetics as the study of passive mutation. Geneticists investigate anatomical characters, never anatomical constructions, which are capable of reorganization when the biological-morphological equilibrium of the organism has been disturbed. The anatomy of Opisthocomus cristatus and Stringops habroptilus demonstrate that three successive disturbances in the bio-morphological equilibrium are reacted to purposively by anatomical reconstruction. These reactions are no accidental mutations, but are anatomical reactions, related to, (...) and affecting, the organism as a whole. In sharp contrast to such anatomical reaction, resulting, during phylogeny, in reorganization, are the “technics” [i.e., mechanistic bases] of individual development. The hereditary process is, like every physiological or embryological process, a fixed mechanism, which remains constant until an active reaction leads to reconstruction and at the same time an appropriate change of the mechanisms. The remolding of species is therefore no passive, “technical” process, but a creative act of the organisms themselves. [Original English abstract; not translated.]. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Normalization and the Welfare StateLadelle McWhorterIn Racism and Sexual Oppression in Anglo-America, I argued that as race was absorbed into biology in the nineteenth century, it was recast from a morphological typology to a function of physiological and evolutionary development (McWhorter 2009b). Racial difference became a sign of developmental difference. Racial groups represented stages of human evolution, and raced individuals were to be disciplined and managed in accordance with (...) developmental norms.Twentieth-century race was therefore a category and tool of normalization; to be raced was to be located at a particular point along a developmental curve. Some races were thought to be more or less arrested in their development, while others were merely retarded, and theorists disagreed at times about which were which. But they all agreed that the most highly developed race was the Nordic or the Anglo-Saxon. Anglo-Saxons were the norm for modern human beings— anatomically, physiologically, intellectually, and morally. There were other white races whose status was debated (Mediterraneans and Ashkenazi Jews, for example), and there were disputes over the evolutionary status of Chinese, Hindus, and Mexicans. But most theorists agreed that at the very bottom of the developmental scale we should place Celts, Negroes, and American Indians. These peoples were savages, primitives. They should be trained to the extent possible to contribute to the society that had already superseded them, but their proper destiny was to pass away into extinction as humanity advanced.These evolutionary stragglers, along with the evolutionary throwbacks that appeared sometimes among whites, were considered dangerous for two main reasons. First, a great many of them were expensive. They were shiftless, often incompetent, and frequently lawless. Because of them, it was necessary to [End Page 39] maintain police forces, prisons, poorhouses, and asylums. They were a drain on the economic advance of society, which affected its educational and technological advance and ultimately its evolutionary advance as well. Second, because they had primitive sexual urges unrestrained by reason as well as heritable defects and diseases, they threatened the bloodlines of more advanced human beings. In short, they posed a risk for the ongoing evolutionary advancement of the entire Human Race. To protect the Race, it was necessary to contain these primitives, savages, and throwbacks and to reduce their numbers through careful management of their sexuality. This, I argued in the book, was racism’s cutting edge in the early twentieth century.Since publishing the book, I have done some work on the changes in practices of racism in the wake of the Biological Synthesis—that is, the unification of biology and genetics that occurred in the 1930s through the efforts of renowned scientists such as Theodosius Dobzhansky and Ernst Mayr (McWhorter 2010a, 2010b, 2010c). As I discussed in that work, by 1950, evolutionary biology was less a study of species development than it was a study of the effects of evolutionary forces acting on and within populations. Correlatively, racial practices shifted toward management of statistically delineated populations or ethnic groups. Theorists and policymakers recognized that not all members of a given population have the same genes, meaning that old-style racism (which assumed, for example, that all Negroes were stupid) was false; some Negroes might be quite brilliant, in fact. It was not The Negro who was stupid but the population of Negroes in the aggregate that was measurably stupider than the population of Anglo-Saxons. Accordingly, normalization now occurred at the level of the population. Disciplinary practices designed for cultivating the capacities of groups of individuals were altered or replaced to focus on groups as groups, as aggregates. The point was to shift the statistical norm of the population rather than to alter the bodies or behavior of each and every individual. I have argued elsewhere (McWhorter 2009a, 5) that this merger of disciplinary normalization and population management constitutes the full flowering of what Foucault calls biopower (Foucault 1978, 140).When Lisa Guenther invited me to speak at the plenary on “Re-thinking Whiteness” that took place at the fifth annual meeting of philoSOPHIA at Vanderbilt University, she explained that although many presenters offer polished papers, it has been a...

For many contemporary Christian theologians, evolutionary biology rules out any account of an Adam and Eve that would explain the origin of our species. In response, I propose that they have uncritically embraced the anti-essentialist presuppositions of the dominant scientific narrative for the origins of our kind. In fact, there are sound and robust reasons to think that human beings share an intrinsic essence that puts them into a natural kind. I also propose that our natural kind can be defined (...) by our developmental capacity for language, which I suggest is needed for abstract thinking. Thus, it is still reasonable to trace the origins of our natural kind to an original individual. He would have been the first anatomically modern human to have evolved this capacity for hierarchical and non-linear language that allowed him to construct an abstract internal map of the world.

The electric activities of cortical pyramidal neurons are supported by structurally stable, morphologically complex axo-dendritic trees. Anatomical differences between axons and dendrites in regard to their length or caliber reflect the underlying functional specializations, for input or output of neural information, respectively. For a proper assessment of the computational capacity of pyramidal neurons, we have analyzed an extensive dataset of three-dimensional digital reconstructions from the NeuroMorphoOrg database, and quantified basic dendritic or axonal morphometric measures in different regions and layers (...) of the mouse, rat or human cerebral cortex. Physical estimates of the total number and type of ions involved in neuronal electric spiking based on the obtained morphometric data, combined with energetics of neurotransmitter release and signaling fueled by glucose consumed by the active brain, support highly efficient cerebral computation performed at the thermodynamically allowed Landauer limit for implementation of irreversible logical operations. Individual proton tunneling events in voltage-sensing S4 protein alpha-helices of Na+, K+ or Ca2+ ion channels are ideally suited to serve as single Landauer elementary logical operations that are then amplified by selective ionic currents traversing the open channel pores. This miniaturization of computational gating allows the execution of over 1.2 zetta logical operations per second in the human cerebral cortex without combusting the brain by the released heat.

This book is divided in two parts, the first of which shows how, beyond paleontology and systematics, macroevolutionary theories apply key insights from ecology and biogeography, developmental biology, biophysics, molecular phylogenetics, and even the sociocultural sciences to explain evolution in deep time. In the second part, the phenomenon of macroevolution is examined with the help of real life-history case studies on the evolution of eukaryotic sex, the formation of anatomical form and body-plans, extinction and speciation events of marine invertebrates, (...) hominin evolution and species conservation ethics. The book brings together leading experts, who explain pivotal concepts such as Punctuated Equilibria, Stasis, Developmental Constraints, Adaptive Radiations, Habitat Tracking, Turnovers, (Mass) Extinctions, Species Sorting, Major Transitions, Trends, and Hierarchies – key premises that allow macroevolutionary epistemic frameworks to transcend microevolutionary theories that focus on genetic variation, selection, migration and fitness. Along the way, the contributing authors review ongoing debates and current scientific challenges; detail new and fascinating scientific tools and techniques that allow us to cross the classic borders between disciplines; demonstrate how their theories make it possible to extend the Modern Synthesis; present guidelines on how the macroevolutionary field could be further developed; and provide a rich view of just how it was that life evolved across time and space. In short, this book is a must-read for active scholars and, because the technical aspects are fully explained, it is also accessible for non-specialists. Understanding evolution requires a solid grasp of above-population phenomena. Species are real biological individuals, and abiotic factors impact the future course of evolution. Beyond observation, when the explanation of macroevolution is the goal, we need both evidence and theory that enable us to explain and interpret how life evolves at the grand scale. (shrink)

Researchers are pursuing various ways to synthesise human male and female gametes, which would be useful for people facing infertility. Some people are unable to conceive children with their partner because one of them is infertile in the sense of having an anatomical or physiological deficit. Other people—in same sex couples—may not be individually infertile but situationally infertile in relation to one another. Segers et al have described a pathway towards synthetic gametes that would rely on embryonic stem cells, (...) rather than somatic cells. This pathway would be advantageous, they say, for same-sex couples even though it would not offer those couples 50%–50% shared genetics in their children but only 50%–25%. It is unclear, however, why this approach should be preferred morally speaking since it represents a falling off from the kind of shared genetics in children that are functionally a gold standard in parents' expectations generally. Despite raising concerns about whether genetic relatedness is necessary or sufficient as a condition of parental interest in children, Segers et al cede the sociocultural importance of that standard. If so, same-sex couples seem entitled to press a case for some measure of research priority that would offer the same level of access to that social good as everyone else. (shrink)

Locke and Leibniz deny that there are any such beings as ‘monsters’ (anomalies, natural curiosities, wonders, and marvels), for two very different reasons. For Locke, monsters are not ‘natural kinds’: the word ‘monster’ does not individuate any specific class of beings ‘out there’ in the natural world. Monsters depend on our subjective viewpoint. For Leibniz, there are no monsters because we are all parts of the Great Chain of Being. Everything that happens, happens for a reason, including a monstrous birth. (...) But what about materialism? Well, beginning with the anatomical interest into ‘monstrous births’ in the French Académie des Sciences in the first three decades of the eighteenth century, there is a shift away from ‘imaginationist’ claims such as those of Malebranche, that if a woman gives birth to a monstrous child it is a consequence of something she imagined. Anatomists such as Lemery and Winslow try to formulate a strictly mechanical explanation for such events, rejecting moral and metaphysical explanations. Picking up on this work, materialist thinkers like Diderot are compelled to reject the very idea of monsters. We are all material beings produced according to the same mechanisms or laws, some of us are more ‘successful’ products than others, i.e. some live longer than others. In his late Eléments de physiologie he says “L’homme est un effet commun, le monstre un effet rare.” Ultimately he arrives at a materialist version of Leibniz’s position: there are no monsters, we are all monsters in each other’s eyes, at one time or another. This conclusion is a pregnant one in light of twentieth century interest in the problem of ‘the normal and the pathological’ (Canguilhem), and the broader question of how materialism relates to the biological world.

In this article, we explore the relation between bodies and selves evident in the narratives surrounding aesthetic surgery. In much feminist work on aesthetic surgery, such narratives have been discussed in terms of the normalising consequences of the objectifying, homogenising, cosmetic gaze. These discussions stress the ways in which we model our bodies, under the gaze of others, in order to conform to social norms. Such an objectified body is contrasted with the subjective body; the body-for-the-self. In this article, however, (...) we wish to make sense of the narratives surrounding such surgery by invoking the expressive body, which fits on neither side of this binary. We wish to explore how the modification of the body’s anatomical features (physiology) is taken to be a modification of its expressive possibilities, and therefore a modification of possibilities for inter-subjective relations with others. It is such expressive possibilities that, we suggest, underlie decisions to undergo surgical procedures. The possibility of modification of the expressive possibilities of the body, by the modification of its anatomical features, rests on the social imaginaries attached to anatomical features. In the context of such imaginaries, individual decisions to undergo or promote surgery can be both intelligible and potentially empowering. However, the social consequences of such acts are an increasing normalisation of the ‘body under the knife’ and an intolerance of bodily difference. This, we suggest, can only be changed by a re-visioning of bodily imaginaries so that expressive possibilities can be experienced across bodies with a range of physiological features. (shrink)

Merging the information from different senses is essential for successful interaction with real-life situations. Indeed, sensory integration can reduce perceptual ambiguity, speed reactions, or change the qualitative sensory experience. It is widely held that integration occurs at later processing stages and mostly in higher association cortices; however, recent studies suggest that sensory convergence can occur in primary sensory cortex. A good model for early convergence proved to be the auditory cortex, which can be modulated by visual and tactile stimulation; however, (...) given the large number and small size of auditory fields, neither human imaging nor microelectrode recordings have systematically identified which fields are susceptible to multisensory influences. To reconcile findings from human imaging with anatomical knowledge from nonhuman primates, we exploited high-resolution imaging (functional magnetic resonance imaging) of the macaque monkey to study the modulation of auditory processing by visual stimulation. Using a functional parcellation of auditory cortex, we localized modulations to individual fields. Our results demonstrate that both primary (core) and nonprimary (belt) auditory fields can be activated by the mere presentation of visual scenes. Audiovisual convergence was restricted to caudal fields [prominently the core field (primary auditory cortex) and belt fields (caudomedial field, caudolateral field, and mediomedial field)] and continued in the auditory parabelt and the superior temporal sulcus. The same fields exhibited enhancement of auditory activation by visual stimulation and showed stronger enhancement for less effective stimuli, two characteristics of sensory integration. Together, these findings reveal multisensory modulation of auditory processing prominently in caudal fields but also at the lowest stages of auditory cortical processing. (shrink)

This paper aims to show that genders are enacted, by providing an account of how an individual can be said to enact a gender and explaining how, consequently, genders can be fluid. On the enactive-ecological view we defend, individuals first and foremost perceive the world as fields of affordances, that is, structured sets of action possibilities. Fields of natural affordances offer action possibilities because of the natural properties of organisms and environments. Handles offer graspability to humans because of physical-structural properties (...) of handles and the anatomical-physiological properties of humans. Although humans live in fields of bodily, action, and cultural affordances, our work focuses on cultural affordances, where action possibilities are offered to individuals because of the normative responses of individuals in that culture. Knocking on a door affords entrance because knocking provides cultured individuals on the other side of the door an affordance to which they themselves behave normatively. Usually, behaving normatively in response to cultural affordances brings about sequences of perception-action loops, which we will call “scripts”: for instance, closed doors afford knocking, which affords the individual inside opening the door, which affords an interpersonal meeting, which afford entrance. Although the notion of script has a strong cognitivist flavor, one of the aims of the paper to provide an ecological account of scripts, to show that what cognitivists viewed as representations are in fact environmentally structured perception-action loops. On our account of gender, gendered cultures build and maintain gendered cultural affordance landscapes, that is, landscapes in which the action possibilities individuals face are normed according to a specific body type or situation; most often biological sex. Individuals enact a given gender when they come to perceive the affordances reserved for one gender by their culture and respond in the culturally normative way, thus enacting gendered sequences of perception-action loops. With the shifting landscapes of cultural affordances brought about by several recent social, technological, and epistemic developments in some cultures, the gendered landscapes of affordances offered to individuals in these cultures have become more varied and less rigid, thus increasing the variety and flexibility of scripts individuals can enact. This entails that individuals in such cultures have an increased possibility for gender fluidity, which may in part explain the increasing number of people currently identifying outside the binary.

Reductive explanations are psychologically seductive; when given two explanations, people prefer the one that refers to lower-level components or processes to account for the phenomena under consideration even when information about these lower levels is irrelevant. Maybe individuals assume that a reductive explanation is what a scientific explanation should look like (e.g., neuroscience should explain psychology) or presume that information about lower-level components or processes is more explanatory (e.g., molecular detail explains better than anatomical detail). Philosophers have been analyzing (...) reduction for more than half a century (Hüttemann and Love 2016), but neither of these possibilities is a consensus view (even if psychologically applicable). Instead, there is widespread agreement that the landscape of reductionism is complicated, especially in biology. Increasing scrutiny of actual practices within biology and other sciences has often provoked the questions (paraphrasing Alasdair MacIntyre): Whose explanation? Which reductionism? Marie Kaiser’s book—Reductive Explanation in the Biological Sciences—is a decisive intervention into these discussions, offering a wealth of helpful distinctions and new analyses with a healthy focus on scientific practices of explanation.

The main purpose of this article is to identify the inner human activity Peirce calls musement with the mental processes that arise through the workings of the brain’s default mode network. This network is a specific, recently anatomically defined brain system, which is most active when individuals are not focused on the external environment. In doing so, musement, which was defined by Peirce over a hundred years ago, will finally be situated within what today we understand as its neurobiological origin.

In lieu of an abstract, here is a brief excerpt of the content:Commentary on “Wilhelm Griesinger”Aaron L. Mishara (bio)Arens situates Wilhelm Griesinger in a historical context with which we are no longer familiar. In doing so, she has performed an important task for contemporary clinicians, philosophers, and historians. We find ourselves working and thinking (both in everyday clinical practice and in the construction of our models of mental disorder) with the same categories that Griesinger struggled to sort out and redefine; (...) we often do so, however, without awareness of their history or lack of permanence. Ackerknecht writes that all the dominant trends in modern psychiatry can be traced back to Griesinger; he states that Griesinger is the “founder of neuropsychiatry,” a “merging of the two disciplines” neurology and psychiatry. Griesinger presents us with a “systematic synthesis of the anatomical, physiological, psychological and clinical points of view” (Ackerknecht 1959, 63). Somewhat contrarily, Karl Jaspers, in his General Psychopathology, groups Griesinger with the great observers and describers of clinical experience rather than among the systematic analyzers (Jaspers 1963, 849–50). Although Griesinger is best known for his identification of mental disorders as a subset of brain diseases, Karl Bonhoeffer, a successor to Griesinger as director of the Charité Clinic in Berlin, cautions that Griesinger “continued to see in psychological causes the most frequent and abundant source of mental disorders” (Bonhoeffer 1911, 53). Kales, Kales, and Vela-Bueno, however, write, “Griesinger was representative of a clinical movement that minimized the value of psychological concepts in the understanding of mental diseases” (Kales, Kales, and Vela-Bueno 1990, 15). Precisely because of his importance, contention surrounds his legacy.If Griesinger is the pioneer of empirical approaches in biological neuropsychiatry (as Ackerknecht and others claim), he is also precursor to philosophical criticisms of their limits. It is not so easy to lump Griesinger to one side of the oppositions with which we think today: Griesinger’s scientific psychiatry (formed on the basis of the newly emergent empirical physiology) was meant to steer between the Scylla of the previously reigning overspeculative romantic medicine and the Charybdis of the antitheoretical and “positivistic” materialism of Magendie. As Arens suggests, even during the same generation of university psychiatry which Griesinger was critical in forming, he was posthumously denounced as belonging to the Hegelian idealists; later, he was proclaimed to be an empiricist. Griesinger’s work contained both idealism and empiricism in a fragile synthesis that soon broke asunder.Hermeneutic theory points out that we inevitably interpret an author, in this case, Griesinger, in terms of the prejudices of our own present context of understanding and our current problems of application to clinical practice (Gadamer 1993). On the one hand, we benefit from the advantage of seeing all that follows Griesinger’s work and are able to “understand the author [End Page 165] better than he understood himself.” We are able to see what he only anticipates but is still not able to explicitly articulate as the unpredicted effects of his work. On the other hand, our interpretations are encumbered by the sedimentations of the views of his successors: his work lies buried under the subsequent interpretations and vicissitudes of a reception with its own agendas, contexts of interpretation, and realms of application. It would be easier if we could simply assign him to one side of our current debates concerning mind/body, individual/culture, and explanation/understanding rather than seeing that our present quandaries in understanding, classifying, and treating mental disorder result precisely from a reading of Griesinger that is not careful enough. It is here that Arens can help us develop our present views further by reviewing their past.Although Griesinger is heralded as the pioneer of an empirical physiological approach which employs a natural scientific concept of mechanism (Ackerknecht, O. Marx, Verwey), Arens situates him in the tradition of Kant and German idealism. It is perhaps this solution of being both philosophical and empirical which seems hard for us, today, to understand. We have come to view these directions as contradictory, to be necessarily in a mutually exclusive relationship. (But that is rather the expression of the present impasse and not the way that Griesinger originally approached these problems.) Arens ambitiously retraces the genealogy of Griesinger’s model...

Disorders of sexual development are a heterogeneous group of disorders in which chromosomal, gonadal or anatomical sex development is atypical. The majority of these children are recognized at birth by ambiguous genitalia. Legal and societal pressures require the physician and parents to assign sex rapidly. Though sex assignment is undebated in several disorders of sexual development, many others need an individualized approach to gender-related concerns. Gender dysphoria is prevalent in disorders of sexual development, and early gender-defining surgeries have potentially (...) lifelong consequences. We use two cases, one of partial androgen insensitivity and another of simple virilizing congenital adrenal hyperplasia to illustrate that in disorders of sexual development, the ethical management principles remain the same at their core despite the vast differences in phenotypes. Sex assignment should maximize functional, psychological and sexual needs. Sex assigned should coincide with gender identity. We propose that we manage such children with the mutual participation of the physician, parents and the child. Though the parents and the physician have the child's best interests when making a decision, the child's developing autonomy should be protected. The communication of the health provider to the parent must be honest if early sex assignment is difficult. (shrink)

The first major advances in the understanding of the neurological bases for language abilities were the results of the study of the brains and behaviors of patients with language impairments due to focal brain damage. The two most prominent pioneers in this field are remembered because their names have become associated with distinctive aphasia (language loss) syndromes and the brain regions associated with them. In 1861 Paul Broca described the damage site in the brain of a patient who had lost (...) the ability to produce articulate speech as a result of a stroke. Broca's aphasia, as it is now commonly called, is produced by damage that involves the inferior left frontal lobe of the brain. It tends to produce both a loss of articulatory skill (sometimes but not always with paralysis) and (as discovered much later) problems with grammar and syntax, including grammatical comprehension under certain conditions. Despite speech production impairments, Broca's aphasics do not have basic word‐ and sentence‐comprehension difficulties, when comprehension is not dependent on syntactic analysis. In 1874 Carl Wernicke demonstrated that damage to the left superior temporal lobe produced a different syndrome of language impairments. Wernicke's aphasia generally spares fluent, syntactic speech but impairs the use and comprehension of content words. Wernicke's aphasics'speech includes inappropriate word substitutions, neologisms, and semantic confusions, and their comprehension is similarly disturbed. These early studies also demonstrated that these aphasic disturbances were almost exclusively associated with damage to the structures of the left cerebral hemisphere, even though anatomically corresponding structures are present on both sides of the brain. However, this is not true of all language functions. Some left‐handed individuals can suffer aphasia from right hemisphere damage, and recent studies of patients with right hemisphere damage without aphasia have demonstrated impairment of their comprehension above the sentence level (e.g., interpretation of jokes and stories) and in the production and interpretation of prosodic features of speech (rhythmic and tonal patterning that conveys emphasis and emotion).

With improved diagnostic capability and accuracy, the fields of medicine, neuroscience, psychiatry, and psychology have benefitted remarkably from the dramatic advancements in neuroimaging technology. Not only can surface and subsurface structures of the brain be mapped with incredible anatomical detail, now neural activity can be imaged across time as the brain responds to different stimuli. These sophisticated techniques have been a vital element in the recent increase in neuroimaging-based research. This increase, while producing new diagnostic techniques and improved treatment (...) mechanisms for neurological disease, has also led to a new dilemma for human subjects researchers: how should incidental findings be managed? An incidental finding is a finding concerning an individual research participant that has potential health or reproductive importance and is discovered in the course of conducting research but is beyond the aims of this study.

In lieu of an abstract, here is a brief excerpt of the content:Aestheticism, Homoeroticism, and Christian Guilt in The Picture of Dorian GrayJoseph CarrollSince the advent of the poststructuralist revolution some thirty years ago, interpretive literary criticism has suppressed two concepts that had informed virtually all previous literary thinking: (1) the idea of the author as an individual person and an originating source for literary meaning, and (2) the idea of "human nature" as the represented subject and common frame of (...) reference for literary depictions. Under the tutelage of Barthes, Derrida, and Foucault, literary critics learned to speak of authors, characters, settings, and plots not as individuals situated in a natural world but as discursive formations constituted by the circulation of linguistic, cultural, and ideological energies. In the three decades during which poststructuralism has dominated academic literary study, a different kind of revolution—evolutionary, Darwinian, and naturalistic—has been transforming the social sciences. Sociobiology, evolutionary psychology, Darwinian anthropology, behavioral ecology, cognitive archaeology, and behavioral genetics do not all agree with one another in every respect, but they are all nonetheless aspects or phases of a common research program. The central working hypothesis in this program is that the human species, like all other species, has evolved in an adaptive relation to its environment and that as a consequence it has a distinct, genetically transmitted, species-typical set of characteristics—anatomical, physiological, hormonal, neurological, and behavioral. That set of characteristics is what in common language is meant by "human nature." Literature has always given us subjectively evocative depictions of human nature, and Darwinian social science is now giving us a more comprehensive and scientifically precise account of it. The sense of [End Page 286] individual agency is one crucial aspect of human nature, and that aspect is now being explored in complementary ways by personality psychology and by cognitive neuroscience.1Over the past decade or so, a scattered handful of literary scholars has broken away from the dominant poststructuralist paradigm and has sought to make use of the new scientific information on human nature.2 The simplest and most obvious way to use this information is to examine the behavior depicted in literary texts and to correlate that behavior with "human universals," that is, with forms of behavior that appear in every known culture and that thus appear to be embedded in the nature of the species. Seeking depictions of universals has produced valuable results for literary study, but this first move in Darwinian criticism does not exhaust the range of possibility in the analysis of literary meaning. Human nature is complex and sometimes divided against itself; individuals vary, and some variations depart from species-typical patterns, even in the most adaptively crucial aspects of survival and reproduction. Moreover, literary meaning involves more than the represented subject matter. Authors imbue texts with meanings and affects peculiar to themselves; authors engage in communicative transactions with audiences; and texts have formal and aesthetic properties that are not reducible to represented subject matter. All of these aspects of the total literary situation are part of literary meaning, and all of them can and should fall within the range of analysis available to Darwinian literary study.3Oscar Wilde's The Picture of Dorian Gray offers two special challenges to Darwinian criticism. First, the novel is saturated with homoerotic sexual feeling, and it thus defies any simple reading in terms of behavior oriented to reproductive success. Second, the central conflicts in the novel involve two competing visions of human nature, and in their conceptual structure neither of those visions corresponds very closely to the quasi-Darwinian conceptual structure implicit in most realist and naturalist fiction. One vision derives from the aestheticist doctrines of Walter Pater, and the other from a traditional Christian conception of the soul. Pater's ideas about human motives and the human moral character are at variance both with Christianity and with Darwinism. Christianity and Darwinism share certain concepts of the human moral and social character, but they couch those concepts in different idioms, and they would invoke wholly different causal explanations for how human nature came to be the way it is. Wilde does not develop his themes in Darwinian terms, but the novel can still be read [End Page... (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Adolph Meyer’s Psychobiology in Historical Context, and Its Relationship to George Engel’s Biopsychosocial ModelEdwin R. Wallace IV (bio)Keywordspsychobiology, integrative models of psychiatry, biopsychosocial modelBefore addressing the importance of Adolf Meyer and the question of his impact on the biopsychosocial model of the psychoanalytical internist George Engel, let us tersely sketch the history of functionalism in medicine/psychiatry, and of the nineteenth/early twentieth century’s progressive abandonment of it in favor of (...) basic science reductive models of “disease,” not illness.FunctionalismWhereas Hippocratic physicians diagnosed diatheses in terms of humoral excesses or deficiencies, their primary emphasis was on the ill person. They began with careful histories of the patient’s complaints and his or her daily life course, customary activities, typical foods and beverages imbibed, and the exacerbation or relief of symptoms associated with any or all of these. They also asked questions about his physical and social environment. They carefully looked for any clinically pertinent signs, and might physically examine the patient or his excretions. When they arrived at a diagnosis (say, an excess of yellow or black bile, or of blood or phlegm), they would educate the patient about it and discuss possible approaches. Although leeching, emetics, or purgatives might be prescribed, “dietetics” was the core of the treatment. Much more than recommendations about dietary intake, this involved conversations about “lifestyle” management in general: exercise, fresh air, habit changes, and perhaps bathing in mineral waters or spas. If the patient were “melancholic” (which then included what we would now consider a variety of psychiatric disorders), he or she might be prescribed daily swimming and other forms of vigorous exercise, conversations with a philosopher, [End Page 347] attendance at theatrical comedies, or even referral to an Asklepian temple for “incubation sleep” and priestly dream interpretation. Often doctors worked closely with physical trainers, to whom they sent their patients. In short, their orientation was holistic (“mind”/”body” integration), directed first and foremost toward an individual ill person.In the second century, C.E. Galen, despite his humoral and anatomical pathologies, was similarly holistic or functionalist. He resorted to a variety of physical examinational methods while also attending to the patient’s mental/emotional status. He described one case where he was attending a woman for syncopal episodes. His examinations of her included his customary attention to the pulse. During one evening session, a servant entered and happened to mention that he had just seen the handsome Pylades dancing. Suddenly her pulse became irregular and she fainted straight away. This led Galen to consider love sickness, and perhaps not humoral or organ pathology. He tested his hypothesis during subsequent visits. Whenever another dancer or actor was mentioned, her pulse remained regular and her sensorium alert, but when Pylades was mentioned the irregular pulse and fainting recurred. Because she was married, Galen realized her insoluble conflict, and treated her accordingly.From the fall of Rome until the rise of University Medicine in the later Middle Ages, medical lore and doctoring was in monastic hands—each monastery had its clerical medic, who might also attend outsiders. They were attuned to the traditional triad of major mental disorders—mania, melancholia, and phrenitis—which they explained somatically. However, they also encountered lesser mental/emotional disorders for which they developed their own nosology. “Scrupulosity,” for example, characterized a committed monk with an unrealistic sense of sinfulness and guilt—which often drove him to self-mortification such as flagellation, hair shirts with chains underneath, and so forth, for which the remedy was kindly pastoral counseling. “Accedia” was akin to our “dysthymia,” whose sufferer was affected by sadness, lassitude, and impaired capacity to carry out the monastic routine. This was viewed as straddling the boundary between sickness and sin. Routine physical labor (“occupational therapy”) and prayers, confession, penance, and “pep talks” were prescribed.When universities with medical schools arose in the latter Middle Ages, students’ educations were mostly bookish and theoretical. Hippocratic and Galenic somatic orientations were still preeminent. (Vesalius would not publish his illustrated anatomical text until 1543.) Dietetics and purgatives, bloodletting, and so on were still favored treatments. Nevertheless, doctors gave considerable time and attention to their patients as ill... (shrink)

Cranial electrical stimulation has been applied at various current levels in both adults and children with neurological conditions with seemingly promising but somewhat inconsistent results. Stimulation-induced spatial electric fields within a specific brain region are likely a significant contributing factor for the biological effects. Although several simulation models have been used to predict EF distributions in the brain, these models actually have not been validated by in vivo CES-induced EF measurements in the live human brain. This study directly measured the (...) CES-induced voltage changes with implanted stereotactic-electroencephalographic electrodes in twenty-one epilepsy participants and then compared these measured values with the simulated ones obtained from the personalized models. In addition, we further investigated the influence of stimulation frequency, intensity, electrode montage and age on EFs in parts of participants. We found both measured voltages and EFs obtained in vivo are highly correlated with the predicted ones in our cohort. In white matter and gray matter, the measured voltages linearly increased when the stimulation intensity increased from 5 to 500 μA but showed no significant changes with changing stimulation frequency from 0.5 to 200 Hz. Electrode montage, but not age, significantly affects the distribution of the EFs. Our in vivo measurements demonstrate that the individualized simulation model can reliably predict the CES-induced EFs in both adults and children. It also confirms that the CES-induced EFs highly depend on the electrode montages and individual anatomical features. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Philosophy, Psychiatry, & Psychology 9.3 (2002) 261-264 [Access article in PDF] Mind, Meaning, and the Brain Thomas Fuchs, MD, PhD Keywords: Mind, brain, meaning, translation, depression. A Systemic View of the Mind Progress in brain research over the past two decades demonstrates the power of the neurobiological paradigm. However, this progress is connected with a restricted field of vision typical of any scientific paradigm. The psychiatrist should be aware (...) of this restriction, because, unlike the brain scientist, he deals with patients, not with brains. The restricted view may be described by the terms of (1) reductionism, (2) reification, and (3) isolation.Reductionism: Neurobiology tends to regard subjectivity as a mere by-product of the brain's activity as a symbol-manipulating machine or an information processor. Consciousness becomes an epiphenomon of the neuronal machinery that, operating behind our back, creates the illusion of a continuous self and of an autonomous will (Churchland 1995; Roth 1996).Reification: Mental or subjective states seem to be localizable in the brain; thoughts or feelings, it appears, may be observed in the colored illumination of cortical and subcortical structures. This results in the belief that brain images could also show the cause of a mental illness, or even the illness itself, which then manifests, for instance, in a reduced metabolic activity in certain areas of the cortex.Isolation: As a further consequence, this view isolates the individual patient and considers his illness separated from the interconnections with his environment. However, on these interconnections his personal experiences and dispositions are founded, and it is the actual interpersonal situation that has triggered his present illness.Walter Glannon's paper successfully counters these tendencies toward a neurobiological reductionism with an extended view of the mind: "... the mind is not located in any one place but is distributed among the brain, the body, and the environment." Of course, who observes someone's brain will never see his thoughts, his pain, or his anxiety. For consciousness is not a localizable object or state at all but a process of relating to something: a perceiving of, remembering of, wishing for, aiming at, and so on. Thus on the phenomenological level, there is nothing like a "mental event" that could be isolated from the world and from the stream of conscious experiences. The mind exists only embedded in the world and in the temporal process of life.The same applies to the biological level: Consciousness is based on the continuous interaction of the brain with the organism, and of the organism as a whole with the environment. The role of the brain for mental phenomena is thus comparable to the role of the heart in the circulatory system or of the lung in the respiratory system. Of course, the lung is the central organ of breathing, but respiration may not be restricted to the [End Page 261] lung, nor to the organism as a whole. It means constant exchange with the environment, and there is no sense in asking whether the air taken in still belongs to the surroundings or already to the organism. The same systemic unity is found in the circle of perception and action mediated by the brain: When I am writing a letter, there is no place in the unity of action where my "self" ends and the "world" begins, no border that separates inner and outer worlds.There is another argument to be raised against the reification of the mind if we consider the aspect of a historical biology. From birth on, our mind as well as the correlated brain structures are essentially formed by social and cultural influences. The brain is not inserted into the world as a prefabricated apparatus but through its plastic development in and from the world. Thus it adapts epigenetically to its specific natural and social environment like a key to a lock. This complementarity makes it impossible to restrict one's view to the anatomic organ and requires an interdisciplinary approach to brain-environment investigation, as for example, under the heading of a "social cognitive neuroscience" (Ochsner and Lieberman 2001).As Glannon goes on to argue, to overcome...

We marvel at the social complexity of insects, marked by anatomically and behaviorally distinguishable castes, division of labor and specialization—but how do such systems evolve? Insect societies are composed of individuals, each undergoing its own developmental process and each containing its own genetic information and experiencing its own developmental and experiential environment. Yet societies appear to function as if the colonies themselves are individuals with novel “social genes” and novel social developmental processes. We propose an alternative hypothesis. The origins of (...) complex social behavior, from which insect societies emerge, are derived from ancestral developmental programs. These programs originated in ancient solitary insects and required little evolutionary remodeling. We present evidence from behavioral assays, selective breeding, genetic mapping, functional genomics and endocrinology, and comparative anatomy and physiology. These insights explain how complex social behavior can evolve from heterochronic changes in reproductive signaling systems that govern ubiquitous and ancient relationships between behavior and ovarian development.

There has been much debate regarding when modern human cognition arose. It was previously thought that the technocomplexes and artifacts associated with a particular timeframe during the Upper Paleolithic could provide a proxy for identifying the signature of modern cognition. It now appears that this approach has underestimated the complexity of human behavior on a number of different levels. As the artifacts, once thought to be confined to Europe 40,000 years ago onwards, can now be found in other parts of (...) the world well before this date, especially in South Africa, this suggests that modern cognition arose well before this period. Moreover, the variability of the archaeological record from the time when anatomically modern humans appeared 200,000 years ago suggests cognitive factors alone are unable to explain the obvious unevenness. In this article, it will be demonstrated how neuro-cognition can be assimilated with population dynamics and the transmission of information between individuals and groups that can provide important insights as to the nature and origins of modern human cognition.

Artificial neural networks have weaknesses as models of cognition. A conventional neural network has limitations of computational power. The localist representation is at least equal to its competition. We contend that locally connected neural networks are perfectly capable of storing and retrieving the individual features, but the process of reconstruction must be otherwise explained. We support the localist position but propose a “hybrid” model that can begin to explain cognition in anatomically plausible terms.

Contemporary medicine views health as the individual’s physical, mental, and social well-being. Oral health plays a crucial role in one’s well-being, as the oral cavity and its surrounding regions execute essential functions in verbal and nonverbal communication, sensing, digestion, and significantly contribute to aesthetic appearance. The multifaceted nature of the notion of oral health, as well as the patient’s needs and autonomous will result in various treatment options for the same oral state, favouring often contrasting ethical values and different aspects (...) of oral health. The objective of this article is to suggest alternative treatment strategies in dentistry with respect to the following factors: extent of rehabilitation, preserving one’s anatomical structures, aesthetic outcome, number of sessions, patient autonomy. Additionally, this article describes the suggested treatment strategies in an ethical context and determines the conditions of their employment. The suggested treatment strategies are divided in two categories, extensive treatment strategies focusing on the patient’s entire craniofacial complex, while specific treatment strategies focus on specific paramount issues.

This volume examines the latest scientific and technological developments likely to shape our post-human future. Using a multidisciplinary approach, the author argues that we stand at the precipice of an evolutionary change caused by genetic engineering and anatomically embedded digital and informational technologies. The author delves into current scientific initiatives that will lead to the emergence of super smart individuals with unique creative capacities. He draws on technology, psychology and philosophy to consider humans-as-they-are relative to autonomy, creativity, and their place (...) in a future shared with ‘post humans.’ The author discusses the current state of bioethics and technology law, both which policymakers, beset by a torrent of revolutionary advances in bioengineering, are attempting to steer. Significantly, Carvalko addresses why we must both preserve the narratives that brought us to this moment and continue to express our humanity through, music, art, and literature, to ensure that, as a uniquely creative species, we don’t simply vanish in the ether of an evolution brought about by our own technology.

Face recognition confronts the same fundamental challenge as all object recognition: the identification of individuals belonging to a specific category despite a huge range in possible appearances. The specialized architecture of the face patch system—the concentration of face cells into modules and the spatial separation of modules—makes it possible to dissect the steps leading to invariant object recognition in unprecedented detail. It discusses both anatomical experiments revealing the connectivity of the six face patches and electrophysiological experiments revealing the response (...) selectivity of single units within the patches. It reviews insights into this question obtained from fMRI and electrophysiological experiments in macaque monkeys. It presents evidence that macaques have specialized face regions and discusses their anatomical connectivity as well as functional properties measured with both fMRI and targeted electrophysiology.

Islamist rhetoric about the humiliation of Islam and American rhetoric about national humiliation have been energized by disparate events in recent years, from the photographs of American soldiers in Mogadishu, Somalia to the invasion of Iraq, the “Innocence of Muslims” video to the attacks on 9/11. At the same time, there’s been an explosion of scholarship on humiliation as a driver of international conflict and political violence in general, and in relation to the bodies and minds of Muslims in particular. (...) The link between humiliation and Muslims is thus a co-production between Islamists who continually invoke it and scholars from various disciplines and regions who regularly posit it. Yet there’s been very little analysis of humiliation in Islamist discourse; minimal effort to anatomize the ways in which this experience of humiliation is constructed to necessitate particular kinds of retaliatory action; and no attempt to theorize more broadly about patterns and discontinuities in how different rhetorics construct humiliation. This article takes up the following questions: What is the substantive content of humiliation in such rhetoric and analysis? Do these different rhetorics of humiliation articulate the same understanding of it, as an act and an experience? What does close analysis of Islamist discourse on humiliation in comparative perspective reveal about the political stakes and affective resonances articulated and energized by it in this particular moment in history? Finally, what do the answers to these questions say about the reach and limits of the dominant account of humiliation as the violated dignity or injured self-respect of a generic individual? (shrink)
