Focusing on the first four images of the Other mobilized in René Descartes’ Meditations—namely, the blind, the mad, the dreamy, and the bad—Reading Descartes Otherwise casts light on what have heretofore been the phenomenological shadows of “Cartesian rationality.” In doing so, it discovers dynamic signs of spectral alterity lodged both at the core and on the edges of modern Cartesian subjectivity. Calling for a Copernican reorientation of the very notion “Cartesianism,” the book's series of close, creatively critical readings of (...) Descartes’ signature images brings the dramatic forces, moments, and scenes of the cogito into our own contemporary moment. While unravelling the knotted skeins of ambiguity that have been spun within philosophical modernity out of such clichés as “Descartes, the abstract modern subject” and “Descartes, the father of modern philosophy,” the analysis highlights a figure who is at once everywhere and nowhere, a living Cartesian ghost. This effort at revitalizing and reframing the legacy of Cartesian modernity, in a way mindful of its proto-phenomenological traces, also involves reflecting on some of the trends in contemporary Cartesian scholarship while putting Descartes in dialogue with a host of twentieth century and contemporary Continental philosophers ranging from Edmund Husserl, Gaston Bachelard and Maurice Merleau-Ponty to Emmanuel Levinas, Michel Foucault, Gilles Deleuze, Jacques Derrida, Jean-Luc Nancy, Jean-Luc Marion, and Alain Badiou among others.

Providing Single Sign-On (SSO) between service providers and enabling service providers to share user personal attributes are critical for both users to benefit from a seamless access to their services, and service providers to realize new business opportunities. Today, however, the users have several independent, partial identities spread over different service providers. Providing SSO and attribute sharing requires that links (federations) are established between (partial) identities. In SAML 2.0 (Maler et al. 2003), the links between identities are stored and managed (...) at the network side by the identity providers (network-side identity federation). This model prevents the service providers from mass-correlating the partial identities they have, but the users must fully trust the identity providers. In this paper, we propose a complementary approach where the users have a full control of the links between their partial identities. It is a client-side identity federation approach, which relies on the introduction of a new cryptographic tool, called invariable partially blind signature scheme, that may be of independent interest.

The physiological blind spot corresponds to the optic disc where the retina contains no light-detecting photoreceptor cells. Our perception seemingly fills in this gap in input. Here we suggest that rather than an active process, such perceptual filling-in could instead be a consequence of the integration of visual inputs at higher stages of processing discounting the local absence of retinal input. Using functional brain imaging, we resolved the retinotopic representation of the physiological blind spot in early human visual (...) cortex and measured responses while participants perceived filling-in. Responses in early visual areas simply reflected the absence of visual input. In contrast, higher extrastriate regions responded more to stimuli in the eye containing the blind spot than the fellow eye. However, this signature was independent of filling-in. We argue that these findings agree with philosophical accounts that posit that the concept of filling-in of absent retinal input is unnecessary. (shrink)

As donor trust legitimises research, trust is vital for research in the fields of biomedicine, genetics, translational medicine and personalised medicine. For parts of the donor community, the consent signature is a sign of trust in research. Many consent processes in biomedical research ask donors to provide their data for an unspecified future use, which introduces uncertainty of the unknown. This uncertainty can jeopardise donor trust or demand blind trust. But which donor wants to trust blindly? To reduce this (...) uncertainty, we explore first, which future-proof actors donors could trust when signing a consent form. Second, we discuss the question Can we know if donor trust expires? and what prevents donor trust from expiring. Finally, we present possible measures that can help to nurture trust in the far future. In this article, we draw on our previous research on trust in biomedical research, on trust in the broader healthcare system and Niklas Luhmann’s and Anthony Giddens’ trust theories. Our findings suggest that, in the far future, researchers will need to consider donor autonomy, as well as societal norms and values of the time period in which the data were donated. They will need to find mechanisms where possible to publicly announce the use of old data sets. However, foremost researchers will need to treat the data respectfully. It remains vital that professionals and the society continue to elaborate on the norms and values that shape the common understanding of what is morally right and wrong when researching data.

Those who have read me, in particular those who have read “Paul de Man’s War,” know very well that I would have quite easily accepted a genuine critique, the expression of an argued disagreement with my reading of de Man, with my evaluation of these articles from 1940-42, and so on. After all, what I wrote on this subject was complicated enough, divided, tormented, most often hazarded as hypothesis, open enough to discussion, itself discussing itself enough in advance for me (...) to be able to welcome questions, suggestions, and objections. Provided this was done so as to demonstrate and not to intimidate or inflict wounds, to help the analysis progress and not to score points, to read and to reason and not to pronounce massive, magical, and immediately executor verdicts. Five of the six “responses” that I reread last night are written, as one used to say, with a pen dipped in venom. Less against the de Man of 1940-42, perhaps, then against me . Less against me, in truth, than against “Deconstruction” . How can the reader tell that these five “critical responses” are not “responses,” critical texts or discussions, but rather the documents of a blinded compulsion? First of all, the fact that they are all monolithic. They take into account none of the complications of which my text, this is the very least one can say, is not at all sparing. They never seek to measure the possibility, the degree, or the form, as always happens in an honest discussion, of a partial agreement on this or that point. No, everything is rejected as a block; everything is a block and a block of hatred. Even when, here or there, someone makes a show of being moved by my sadness or my friendship for de Man, it is in order to get the better of me and suggest that I am inspired only by friendship, which will appear ridiculous to all those who have read me. Inspired by friendship means for those people misled by friendship. How foreign this experience must be to them!

One could accuse me here of making a big deal and a whole history out of words and gestures that remain very clear. When Madame de Mainternon says that the King takes her time, it is because she is glad to give it to him and takes pleasure from it: the King takes nothing from her and gives her as much as he takes. And when she says, “I give the rest to Saint-Cyr, to whom I would like to give (...) all,” she is confiding in her correspondent about a daily economy concerning the leisures and charities, the works and days of a “grande dame” somewhat overwhelmed by her obligations. None of the words she writes has the sense of the unthinkable and the impossible toward which my reading would have pulled them, in the direction of giving-taking, of time and the rest.

In lieu of an abstract, here is a brief excerpt of the content:Surfing the Sublime:Tim Winton's Breath and Eco-HeroismSteve Mentz (bio)The sublime represents an ecological problem. Breathing poses an entangled solution. Surfing, in which a human body stands upright inside a rotating barrel of unbreathable whitewater, provides a way to imagine the connection between these two things.The sublime has represented an elevated category of literary language since the classical writer Longinus's On the Sublime (~1st century CE). From the start, the (...) sublime captures grandeur and also an excess that challenges human thinking. Many of the essential Romantic and Post-Romantic tropes of the sublime that would later appear in dense philosophical accounts, from Edmund Burke and Immanuel Kant to Jean-Francois Lyotard and Jacques Derrida, show themselves embryonically in Longinus's brief classical description.1 The key force of sublime style, Longinus emphasizes, is irrationality: "A lofty passage does not convince the reason of the reader, but takes him out of himself. That which is admirable ever confounds our judgment" (1.4). The conceptual violence of the sublime strains our imaginations almost to breaking, and Longinus's intuition that sublimity always sits on the far side of human comprehension becomes a central feature of this idea in literary history. Although we know very little about Longinus the author–neither his name nor the century in which he lived are certain–he fingers the particular pleasurable pain and rupture of coherence that would become the signature of the sublime in modern poetics. The problem with the sublime perspective is that it craves rupture, centers the human imagination, and refuses to make space for nonhuman collaborators. The opposite of the sublime's imaginative conquest of the world may be simple breathing, the taking of alien air into one's lungs and body, and the environmental dependence each breath marks.The philosopher Graham Harman has recently traced the sublime lineage of Burke and Kant to Lyotard, Levinas, Derrida, and other twentieth-century thinkers, in order to reject the concept as fundamentally [End Page 79] anthropocentric. Harman instead advocates for a philosophy that does not require the shaping structures of human perspective. He argues for an ecological art that engages with the world beyond the merely human perspective, "art that explores unforeseen interactions between the different parts of the external world." What Harman terms "unsublime ecology" might reasonably be described as an inhuman ecological perspective. The philosopher reminds us that the sublime has always been, both from Longinus and in Harman's reading explicitly from Kant and Burke to Lyotard and Derrida, a ju-jitsu trick in which the imagination of a (white male) subject reintegrates what it cannot fully comprehend. The list of poetic works whose language most commonly appears as exemplary of the sublime–Milton's Paradise Lost, Shelley's "Mont Blanc," Shakespeare's King Lear, Wordsworth's The Prelude–suggest that the mode appeals to poetic egoists of a particularly masculinine type.2The heroic sublime of these poets and theorists falters on the physical fact of breathing. Each day of their lives, more than 20,000 times per day, every one of these men, even stern, blind Milton dictating his prophetic poem to dutiful daughters after his revolution had failed, drew nonhuman air into and out of his lungs, exchanging oxygen and carbon dioxide. Each man's thinking continued, while their minds dwelled little on how their body's dependence on alien matter to suspire might impinge upon the heroic sense of self. Even prophets and geniuses, even Wordsworth and Derrida, depend on unconscious patterns. Even the greatest of poets breathes.That's where surfing comes in, in particular Tim Winton's 2008 surf novel Breath, which relates a minor-key epic of surfing against breathing. The novel's core figures devote themselves to intentional oxygen deprivation: our teenage narrator-hero Pikelet; his rebellious buddy Loonie; Sando, the Australian surf-seer they follow; and Sando's American one-time freestyle skier wife, Eva (note the unsubtle symbolism of her name), whose injured knee keeps her off the snow but does not prevent her from chasing sublimity through self-suffocating games that involve sex, a plastic bag, and eventually Pikelet.

Alexander Sokurov’s latest film, Francofonia (2015), produced by the Louvre and filmed in France, takes up the issue of the Louvre in the middle of World War II and the Nazi occupation of Paris. This quasi-documentary, filmed along the lines of Sokurov’s signature documentary “elegies,” also encompasses the history of the Louvre up to the present day. Francofonia follows in the long line of Sokurov’s other films set in museums. Sokurov is an author who has worked more than any other (...) filmmaker to translate paintings into a cinematic medium. While engaging with art history and great museums, however, Sokurov also gives a poignant interpretation of the violence of history that often surrounds great works of art. Thus the museum, in Sokurov’s cinematic interpretation, is both an archive of the most valuable products of civilization, as well as a material monument to the founding cultural and political violence that produced and surrounds it. The overt scrutiny and hypervigilance with which Sokurov films museums affects the very mode of his filming: his camera operates as if it were a museum itself, each film becoming an attempt to save civilization from its own ruination, and from its own blindness. Every frame in Sokurov’s films is thus a freeze-frame, born out of the paralyzing tension between external historical nihilism and the beauty of art. (shrink)

Reality is two-fold, composed of the lighted world as revealed in Genesis, and the darker primordiality which preceded it. The illuminated represents that which the human mind can comprehend, manipulate and re-order to its will: a “designed” and mechanical universe of parts. But behind it, in the backspace of reality, remains the darkness. A formless state of pre-creation, the darkness exists as an endless series of intertwining “signatures” – single possibilities waiting to be created in the illuminated forefront of (...) reality. Permitting each and every part of the lighted world to be connected to the rest, it possesses a “design” all of its own. The question is, if we are blind in the dark, how could we ever come to know it? (shrink)

Readers beware! This book is other than it first seems. Ludwig Wittgenstein’s latest philosophical offering is unlike anything that we have had from him to date. Its preface warns that the Tractatus is no textbook. This is an extreme understatement; really it is a deep puzzle—one that must be handled with great care. As the first lines signal there has been a radical change in the author’s characteristic style. Gone are the ingenious, probing explorations of topics undertaken in his highly (...) fragmentary writings that have been Wittgenstein’s trademark to date. In his new book Wittgenstein abandons the interrogative that his signature vision of and approach to philosophy found in his many masterpieces—The Blue and Brown Books, The Philosophical Investigations, and On Certainty. His previous masterworks have prosecuted a continuous philosophical enterprise designed to expose, resist and reject certain deeply compelling pictures that attract, mesmerize and blind us when it comes to thinking ..

Ethical thought experiments such as the trolley dilemma have been investigated extensively in the past, showing that humans act in utilitarian ways, trying to cause as little overall damage as possible. These trolley dilemmas have gained renewed attention over the past few years, especially due to the necessity of implementing moral decisions in autonomous driving vehicles. We conducted a set of experiments in which participants experienced modified trolley dilemmas as drivers in virtual reality environments. Participants had to make decisions between (...) driving in one of two lanes where different obstacles came into view. Eventually, the participants had to decide which of the objects they would crash into. Obstacles included a variety of human-like avatars of different ages and group sizes. Furthermore, the influence of sidewalks as potential safe harbors and a condition implicating self-sacrifice were tested. Results showed that participants, in general, decided in a utilitarian manner, sparing the highest number of avatars possible with a limited influence by the other variables. Derived from these findings, which are in line with the utilitarian approach in moral decision making, it will be argued for an obligatory ethics setting implemented in ADVs. (shrink)

Wittgenstein’s first account of meaning was that sentences are pictures: the meaning of a sentence is a state of affairs it portrays. States of affairs are arrangements of some basic entities, the Objects. Sentences consist of names of Objects; an arrangement of such names, i.e., a sentence, shows how the named Objects are arranged. A sentence says that the state of affairs it thus pictures exists, hence it is true or false. That theory of meaning as picturing is based on (...) a primitive relation of naming, but what it is for an item to name another the Tractatus does not say. (shrink)

Predicates such as tall or to know Latin, which intuitively denote permanent properties, are called individual-level predicates. Many peculiar properties of this class of predicates have been noted in the literature. One such property is that we cannot say #John is sometimes tall. Here is a way to account for this property: this sentence sounds odd because it triggers the scalar implicature that the alternative John is always tall is false, which cannot be, given that, if John is sometimes tall, (...) then he always is. This intuition faces two challenges. First: this scalar implicature has a weird nature, since it must be surprisingly robust (otherwise, it could be cancelled and the sentence rescued) and furthermore blind to the common knowledge that tallness is a permanent property (since this piece of common knowledge makes the two alternatives equivalent). Second: it is not clear how this intuition could be extended to other, more complicated properties of individual-level predicates. The goal of this paper is to defend the idea of an implicature-based theory of individual-level predicates by facing these two challenges. In the first part of the paper, I try to make sense of the weird nature of these special mismatching implicatures within the recent grammatical framework for scalar implicatures of Chierchia (Structures and beyond, 2004) and Fox (2007). In the second part of the paper, I show how this implicature-based line of reasoning can be extended to more complicated properties of individual-level predicates, such as restrictions on the interpretation of their bare plural subjects, noted in Carlson (Reference to kinds in English. Doctoral dissertation, University of Massachusetts at Amherst, 1977), Milsark (Linguistic Analysis 3.1: 1–29, 1977), and Fox (Natural Language Semantics 3: 283–341, 1995); restrictions on German word order, noted in Diesing (Indefinites, 1992); and restrictions on Q-adverbs, noted in Kratzer (The Generic Book, ed. Carlson and Pelletier, 125–175, 1995). (shrink)

The process of dehumanization, or thinking of others as less than human, is a phenomenon with significant societal implications. According to Haslam's model, two concepts of humanness derive from comparing humans with either animals or machines: individuals may be dehumanized by likening them to either animals or machines, or humanized by emphasizing differences from animals or machines. Recent work in cognitive neuroscience emphasizes understanding cognitive processes in terms of interactions between distributed cortical networks. It has been found that reasoning about (...) internal mental states is associated with activation of the default mode network and deactivation of the task positive network ; whereas reasoning about mechanical processes produces the opposite pattern. We conducted two neuroimaging studies. The first examined the neural bases of dehumanization and its relation to these two brain networks, using images and voice-over social narratives which either implicitly contrasted or implicitly likened humans to either animals or machines. The second study addressed a discrepancy between findings from the first study and prior work on the neural correlates of dehumanization: using a design similar to prior work we examined neural responses to pictures of humans, animals and machines, presented without any social context. In both studies, human and humanizing conditions were associated with relatively high activity in the DMN and relatively low activity in the TPN. However, the non-human and dehumanizing conditions deviated in different ways: they demonstrated more marked changes either in the DMN or in the TPN. Notably, differences between the animal dehumanizing and humanizing conditions were most evident in regions associated with mechanistic reasoning, not in the mentalizing network. Conjunction analysis of contrasts from both paradigms revealed that only one region was consistently more active when participants saw human, a medial parietal region regarded as the central hub of the DMN. These findings provide a neural basis for Haslam's distinction between two types of dehumanization, and suggest that the DMN and TPN play opposing roles in creating a sense of moral concern.

In the current climate of high-stakes testing and performance-based accountability measures, there is a pressing need to reconsider the nature of teaching and what capacities one must develop to be a good teacher. Educational policy experts around the world have pointed out that policies focused disproportionately on student test outcomes can promote teaching practices that are reified and mechanical, and which lead to students developing mere memorisation skills, rather than critical thinking and conceptual understanding. Philosophers of dialogue and dialogic teaching (...) offer a different view of teaching, one that counters mechanical, transmissive or ‘monologic’ teaching. In this paper, I seek to extend the notion of dialogic teaching as a method of supporting social and moral learning processes. Specifically, my focus is on answering the question: What capacities must a teacher have to engage students dialogically? Drawing on Paulo Freire and other contemporary philosophers, I examine dialogic interaction as involving a way of ‘being with learners’ and put forth three teacher capacities necessary for dialogic teaching: self-critique, narrativity and building community. I then examine further what is concretely entailed in the practice of dialogic teaching using research in educational psychology. I aim to highlight how dialogic teaching, unlike monologic teaching, involves the teacher's active ability to support learners’ identification and exploration of their own blind spots—that is, the limits of knowledge and ability—and those of others. Following this, I consider implications of my discussion for international policy on teacher assessment. I close the paper with considerations for future research on teacher capacity and teacher evaluation. This paper contributes to our understanding of teacher capacity and the nature and aims of good teaching. (shrink)

Color-vision defects constitute a spectrum of disorders with varying degrees and types of departure from normal human color vision. One form of color-vision defect is dichromacy; by mixing together only two lights, the dichromat can match any light, unlike normal trichromatic humans, who need to mix three. In a philosophical context, our titular question may be taken in two ways. First, it can be taken at face value as a question about visible properties of external objects, and second, it may (...) be interpreted as the more intangible question of “what it’s like” to be color-blind.

Shoemaker (1996) presenteda prioriarguments against the possibility of ‘self‐blindness’, or the inability of someone, otherwise intelligent and possessed of mental concepts, to introspect any of her concurrent attitude states. Ironically enough, this seems to be a position that Gopnik (1993) and Carruthers (2006, 2008, 2009a,b) have proposed as not only possible, but as the actual human condition generally! According to this ‘Objectivist’ view, supposed introspection of one's attitudes is not ‘direct’, but an ‘inference’ of precisely the sort we make about (...) the attitudes of others, an inference that has the advantage in our own case ofonlyour own sensory data and memories, our behavior, and of the context we are in; i.e. we are all substantially self‐ blind. After sorting out a number of methodological and verbal issues, I argue, first, that thea prioriarguments against Objectivism don't succeed, and that Gopnik and Carruthers are right to regard the issue as an empirical one. On the other hand, I think they seriously underestimate the difficulty of establishing Objectivism. It is unlikely there is an inferential procedure from the data of pure sensation, behavior and context to the relevant self‐attributions that would be as spectacularly reliable as people manifestly seem to be. Moreover, there is a simpler model: the mind very likely consists of a panoply of sub‐routines some of whose outputs are ‘tagged’ for their having been so processed, rather in the way that software ‘documents’ are on standard computers. Introspection plausibly consists in a person's simply attending to distinctive constellations of these tags, even though they may lack phenomenal feels. This draws attention to an important independent fact: that much of phenomenology (or ‘what it's like’ to be in a certain state) may be constituted by facts that are not phenomenal. (shrink)

If the sight of cortically blind people were restored, could they visually recognize a cube or a sphere? This is Molyneux’s question. I argue that the answer to this question depends on the specificities of the mental setup of these cortically blind people. Some cortically blind people have (sometimes quite vivid) visual imagery. Others don’t. The answer to Molyneux’s question depends on whether the blind subjects have had visual imagery before their sight was restored. If they (...) did, the answer to Molyneux’s question is yes, if they didn’t, the answer is no. There is no generic answer to Molyneux’s question. (shrink)

The study has two objectives: to introduce grip force recording as a new technique for studying embodied numerical processing; and to demonstrate how three competing accounts of numerical magnitude representation can be tested by using this new technique: the Mental Number Line, A Theory of Magnitude and Embodied Cognition account. While 26 healthy adults processed visually presented single digits in a go/no-go n-back paradigm, their passive holding forces for two small sensors were recorded in both hands. Spontaneous and unconscious grip (...) force changes related to number magnitude occurred in the left hand already 100–140 ms after stimulus presentation and continued systematically. Our results support a two-step model of number processing where an initial stage is related to the automatic activation of all stimulus properties whereas a later stage consists of deeper conscious processing of the stimulus. This interpretation generalizes previous work with linguistic stimuli and elaborates the timeline of embodied cognition. We hope that the use of grip force recording will advance the field of numerical cognition research. (shrink)

Two recent novels, Ian McEwan’s Atonement and Margaret Atwood’s The Blind Assassin, are philosophically instructive. These books are interesting, I argue, because they reveal something about understanding and appreciating narrative. They show us that audience’s participation in narrative is much more subtle and complex than philosophers generally acknowledge. An analysis of these books reveals that narrative imagining is not static or unified, but dynamic and multipolar. I argue that once the complexity of narrative engagement is better understood, some prominent (...) philosophical problems and debates concerning narrative dissolve. (shrink)

Contemporary debates about scientific institutions and practice feature many proposed reforms. Most of these require increased efforts from scientists. But how do scientists’ incentives for effort interact? How can scientific institutions encourage scientists to invest effort in research? We explore these questions using a game-theoretic model of publication markets. We employ a base game between authors and reviewers, before assessing some of its tendencies by means of analysis and simulations. We compare how the effort expenditures of these groups interact in (...) our model under a variety of settings, such as double-blind and open review systems. We make a number of findings, including that open review can increase the effort of authors in a range of circumstances and that these effects can manifest in a policy-relevant period of time. However, we find that open review’s impact on authors’ efforts is sensitive to the strength of several other influences. (shrink)

This paper addresses the question what the fundamental nature and mode of being of institutional reality is. Besides the recent debate with Tony Lawson, Barry Smith is also one of the relatively few authors to have explicitly challenged John Searle's social ontology on this metaphysical question, with Smith's realism requirement for institutions conflicting with Searle's requirement of a one-world naturalism. This paper proposes that an account of institutions as powers or dispositions is not only congenial to Searle's general account, but (...) can also satisfy both the realism and the one world requirements. Searle's worry that such a dispositional account is unable to account for the deontic nature of institutions is countered by an appeal to higher-order powers as well as Searle's notion of the gap and desire-independent reasons for action.

Background: There is a growing interest in using cognitive behavioural therapy with people who have Asperger Syndrome and comorbid mental health problems. Aims: To examine whether modified group CBT for clinically significant anxiety in an AS population is feasible and likely to be efficacious. Method: Using a randomised assessor-blind trial, 52 individuals with AS were randomised into a treatment arm or a waiting-list control arm. After 24 weeks, those in the waiting-list control arm received treatment, while those initially randomised (...) to treatment were followed-up for 24 weeks. Results: The conversion rate for this trial was high, while attrition was 13%. After 24 weeks, there was no significant difference between those randomised to the treatment arm compared to those randomised to the waiting-list control arm on the primary outcome measure, the Hamilton Rating Scale for Anxiety. Conclusions: Trials of psychological therapies with this population are feasible. Larger definitive trials are now needed.

Dance – as a ritual, therapy, and leisure activity – has been known for thousands of years. Today, dance is increasingly used as therapy for cognitive and neurological disorders such as dementia and Parkinson’s disease. Surprisingly, the effects of dance training on the healthy young brain are not well understood despite the necessity of such information for planning successful clinical interventions. Therefore, this study examined actively performing, expert-level trained college students as a model of long-term exposure to dance training. To (...) study the long-term effects of dance training on the human brain, we compared 20 young expert female Dancers with normal body mass index with 20 age- and education-matched Non-Dancers with respect to brain structure and function. We used diffusion tensor, morphometric, resting state and task-related functional MRI, a broad cognitive assessment, and objective measures of selected dance skill (Dance Central video game and a balance task). Dancers showed superior performance in the Dance Central video game and balance task, but showed no differences in cognitive abilities. We found little evidence for training-related differences in brain volume in Dancers. Dancers had lower anisotropy in the corticospinal tract. They also activated the action observation network (AON) to greater extent than Non-Dancers when viewing dance sequences. Dancers showed altered functional connectivity of the AON, and of the general motor learning network. These functional connectivity differences were related to dance skill and balance and training-induced structural characteristics. Our findings have the potential to inform future study designs aiming to monitor dance training-induced plasticity in clinical populations. (shrink)
