Consciousness and Neuroscience

We should be suspicious of the idea that experiencing pain could enable animals to trade off different motivations in a common currency. It is not even clear that humans have a common motivational currency reflected in evaluative experience. Instead, pain may capture attention, inhibiting attention to competing motivations and needs, thereby making genuine trade-offs harder. Our criteria for pain in invertebrates should be part of a more subtle theory of the relationship between pain and decision-making.

What is the temporal structure of conscious experience? While it is popular to think that our most basic conscious experiences are temporally extended, we will be arguing against this view, on the grounds that it makes our conscious experiences depend on the future in an implausible way. We then defend an alternative view of the temporal structure of experience from a variety of different objections. Along the way, we hope to illustrate the wider philosophical ramifications of the relationship between experience (...) and time. What one thinks about the temporal structure of experience is, we believe, deeply interconnected with issues concerning whether consciousness is vague or precise, whether conscious states can be reduced to physical states, whether phenomenal properties are intrinsic properties, and whether phenomenal consciousness can “overflow” access consciousness. As we will see, even seemingly unrelated metaphysical questions, such as the debate between Humean and Non-Humean accounts of natural necessity, bear on questions about the relationship between experience and time.

We suggest that there is confusion between why consciousness developed and what additional functions, through continued evolution, it has co-opted. Consider episodic memory. If we believe that episodic memory evolved solely to accurately represent past events, it seems like a terrible system—prone to forgetting and false memories. However, if we believe that episodic memory developed to flexibly and creatively combine and rearrange memories of prior events in order to plan for the future, then it is quite a good system. We (...) argue that consciousness originally developed as part of the episodic memory system—quite likely the part needed to accomplish that flexible recombining of information. We posit further that consciousness was subsequently co-opted to produce other functions that are not directly relevant to memory per se, such as problem-solving, abstract thinking, and language. We suggest that this theory is compatible with many phenomena, such as the slow speed and the after-the-fact order of consciousness, that cannot be explained well by other theories. We believe that our theory may have profound implications for understanding intentional action and consciousness in general. Moreover, we suggest that episodic memory and its associated memory systems of sensory, working, and semantic memory as a whole ought to be considered together as the conscious memory system in that they, together, give rise to the phenomenon of consciousness. Lastly, we suggest that the cerebral cortex is the part of the brain that makes consciousness possible, and that every cortical region contributes to this conscious memory system. (shrink)

Reflection on the relationship between free will and consciousness has mainly revolved around Libet-style experiments, for example by criticizing the claim that conscious intentions never cause what we do. Less attention has been paid to whether this response captures the sense in which consciousness is relevant for free will, however. In this paper I argue that scholars seem to accept two assumptions they should reject: (1) that the relationship between free will and consciousness is best characterized in terms of conscious (...) states and/or processes being part of the causal chain leading up to the action, and (2) that the third-person perspective is a suitable means to capturing the relationship between free will and consciousness. I provide an alternative proposal of how free will and consciousness may be related, in which an agent’s self-understanding of what she is doing and why, while acting, takes center stage. In order to capture the relationship between the two, I argue, the first-person perspective should be investigated instead of explained away. (shrink)

This paper pursues two lines of inquiry. First, drawing on evidence from clinical literature on borderline states of consciousness, I propose a new categorical framework for liminal states of consciousness associated with certain forms of meditative attainment; second, I argue for dissociating phenomenal character from phenomenal content in accounting for the etiology of nonconceptual states of awareness. My central argument is that while the idea of nonconceptual awareness remains problematic for Buddhist philosophy of mind, our linguistic and categorizing practices cannot (...) be adequately explained without considering the ways in which the first-person phenomenology grounds a more basic level of cognitive and affective sensing.

Laura Specker Sullivan (2022) makes a fairly compelling case for the value of the perspectives of Buddhist practitioners in neuroethics. In this study, Tibetan Buddhist monks have been asked, among other things, whether consciousness, in brain-injured patients in a minimally conscious state, entails a duty to preserve life. In our view, some of the participants’ responses could be used to inform the bioethical debate on death determination.

A breathtaking look at the new science that can track consciousness deep in the brain How does our brain generate a conscious thought? And why does so much of our knowledge remain unconscious? Thanks to clever psychological and brain-imaging experiments, scientists are closer to cracking this mystery than ever before. In this lively book, Stanislas Dehaene describes the pioneering work his lab and the labs of other cognitive neuroscientists worldwide have accomplished in defining, testing, and explaining the brain events behind (...) a conscious state. We can now pin down the neurons that fire when a person reports becoming aware of a piece of information and understand the crucial role unconscious computations play in how we make decisions. The emerging theory enables a test of consciousness in animals, babies, and those with severe brain injuries. A joyous exploration of the mind and its thrilling complexities, Consciousness and the Brain will excite anyone interested in cutting-edge science and technology and the vast philosophical, personal, and ethical implications of finally quantifying consciousness.

The human brain is the first computer to which all others are compared. Yet we know painfully little about how a brain accomplishes its peculiar computations. In particular, consciousness is at once familiar and mysterious, and needs to be understood both for science and for medicine. Boldly, but gently this book introduces a reader to the neural circuitry that achieves consciousness. This amazing interconnection enables consciousness to flow like a stream, intimately relevant to the outside world; and for this to (...) happen, fundamental cues emerge from mental images to bring forth associated recalls. Alas cues can be inconsistent, causing memory failure; fortunately a subliminal cue editor encourages remembering forgotten items. Furthermore, cues generally address several memories, forcing the brain to make a selection. This necessitates another special circuit whose purpose is subliminal editing. The simplified explanations provided in this book make it clear that neurons do far more than ordinary devices, since a single neuron is capable of remarkably dense combinational and sequential logic. Beginning with their interesting and unexpected logical behavior, the reader will genuinely enjoy Dr. Burger's synthesis of a system for biological consciousness, a system that may someday result in credible artificial consciousness.

Contrasting conditions with and without conscious experience has served consciousness research well. However, research based on this simple contrast has led to controversies about the neural basis of conscious experience. One key reason for these ongoing debates seems to be that the simple contrast between conditions with and without consciousness is not specific for unraveling the neural basis of conscious experience, but rather also leads to other processes that precede or follow it. Acknowledging this methodological problem implies that some of (...) the previous research findings about the neural underpinnings of conscious experience are actually reflecting the prerequisites and consequences rather than the direct correlates of conscious perception. Thus, it is required to re-evaluate the previous results to find out which of them are telling us anything about the neural basis of consciousness. But first and foremost, to overcome this methodological problem we need new experimental paradigms that go beyond the simple contrastive analysis or find the ways how some older but well forgotten paradigms may foster a new look at this emerging problem. Accordingly, this research topic is looking for empirical and theoretical contributions that: 1) envision new and suitable experimental approaches to study consciousness that are free from the limitations of the simple contrastive analysis; 2) provide empirical data that help to separate the neural correlates of conscious experience from the prerequisites and consequences of it; 3) help to re-assess previous research findings about the neural correlates of conscious perception in the light of the methodological problems with the traditional contrastive analysis. We hope that the theoretical insights and experimental approaches collected within this Research Topic help us to gain a more refined understanding of the neural basis of conscious experience.

Aims to show that the brain is not responsible for consciousness, and uses this assertion to explore profound love and human connection.

When celebrated neuropsychologist Paul Broks's wife died of cancer, it sparked a journey of grief and reflection that traced a lifelong attempt to understand how the brain gives rise to the soul. The result of that journey is a gorgeous, evocative meditation on fate, death, consciousness, and what it means to be human. The Darker the Night, The Brighter the Stars weaves a scientist's understanding of the mind - its logic, its nuance, how we think about what makes a person (...) - with a poet's approach to humanity, that crucial and ever-elusive why. It's a story that unfolds through the centuries, along the path of humankind's constant quest to discover what makes us human, and the answers that consistently slip out of our grasp. It's modern medicine and psychology and ancient tales; history and myth combined; fiction and the stranger truth. But, most importantly, it's Broks' story, grounded in his own most fascinating cases as a clinician--patients with brain injuries that revealed something fundamental about the link between the raw stuff of our bodies and brains and the ineffable selves we take for who we are.Tracing a loose arc of loss, acceptance, and renewal, he unfolds striking, imaginative stories of everything from Schopenhauer to the Greek philosophers to jazz guitarist Pat Martino in order to sketch a multifaceted view of humanness that is as heartbreaking at it is affirming.

How making up our minds and the makeup of our minds can help us live better and die better. We live in a climate where feelings trump reason and evidence. Lies are treated as "alternative facts." At the same time, it seems our culture does not want us to treat altered or higher states of consciousness seriously. Focusing both on evidence and on such states of consciousness can reorient our attitudes. Jack Crittenden asks the reader to think about life after (...) death, about the basis of morality and the essence of spirituality, about the meaning of happiness, about the path of dying, and about the proper role of work in our lives and how education connects to that role. What if our memories, thoughts, and whole personality lived on after we died? What if morality were based on reasons and evidence and not on God and sacred texts? What if happiness lies not in what we think, how we feel, and what we long for, but in living in the present and in the dying of the self itself? Experiences of and the evidence on altered and higher states of consciousness can lead us to better lives and better deaths. (shrink)

In Sherrington's Loom, Alan McComas provides a historical account of the research that has led to recognition of key mechanisms underlying consciousness. Evidence is assembled from a rich variety of sources--neurological patients, animal behavior, laboratory studies, and especially brain stimulation and recording in humans and animals. Among the remarkable advances in the field has been the ability to identify nerve cells in the human brain that store memories of specific people, places, and objects. In addition to dealing with the issue (...) of "free will," the book assembles the information into possible working models for sensations, intentions, and actions. McComas concludes by considering the possibility of consciousness in artificially intelligent systems. (shrink)

The Problem of Consciousness This chapter will introduce you to consciousness and its most important characteristics. We will look at definitions of consciousness, and examine what it means to say that consciousness is a private experience. We will look at the idea that it is like something to be you or me. The chapter mentions ideas and themes that will be covered in more detail in the rest of the book, and explains why the topic is an important one. Research (...) on consciousness is big on questions but shorter on answers. Nevertheless these questions are central to what it means to be human, or indeed at the heart of what it's like to be anything - what it's like to be conscious. Think of yourself just now. What does it feel like you to be you right at this moment? Think of a loved one. What do you think it is like to be them? Do they know exactly what they're feeling, and do you know just what they're feeling? We might have some idea, but the answer in both cases is no, and not only "no", we can't see how we ever could know for sure. It's my consciousness and your consciousness. (shrink)

Feinberg and Mallatt, in their presentation of neurobiological naturalism, have suggested that visual consciousness was acquired by early vertebrates and inherited by a wide range of descendants, and that its neural basis has shifted to nonhomologous nervous structures during evolution. However, their evolutionary scenario of visual consciousness relies on the assumption that visual consciousness is closely linked with survival, which is not commonly accepted in current consciousness research. We suggest an alternative idea that visual consciousness is linked to a specific (...) class of agency, consequently justifying their phylogenetic claim. We also examine the implication of their phylogenetic claim: visual consciousness is homologous across vertebrates, but its neural basis is not. This apparent incongruence illustrates a general phenomenon of homology, and that the resulting hierarchical view of visual consciousness and its neural basis can be straightforwardly accommodated by neurobiological naturalism. Throughout these discussions, we aim to address the potential theoretical issues in neurobiological naturalism and refine the picture illustrated by Feinberg and Mallatt regarding phylogenetic distribution and trajectories of visual consciousness.

Proponents of the higher-order (HO) theory of consciousness (e.g., Lau and Rosenthal) have recently appealed to brain lesion evidence to support their thesis that mental states are conscious when and only when represented by other mental states. This article argues that this evidence fails to support HO theory, doing this by first determining what kinds of conscious deficit should result when HO state-producing areas are damaged, then arguing that these kinds of deficit do not occur in the studies to which (...) HO theorists appeal. The article also develops an apparatus that can be used to evaluate whether other lesion evidence con- firms or disconfirms HO theory. (shrink)

The Hippocratic Oath is a code of ethics defining correct behaviour by physicians they are required to commit themselves to before being accepted into the profession. It was the first code of ethics for any profession. While originating in Ancient Greece, it subsequently evolved, but the current code still embodies many of the core injunctions of the original code. The most widely accepted current form is the 2006 The Declaration of Geneva by the World Medical Association to be taken before (...) being admitted as a member of the medical profession. The most important of its injunctions are: ‘The health of my patient will be my first consideration’ and ‘I will maintain the utmost respect for human life’. The first is a rewording of the injunction from Epidemics, Book I, of the Hippocratic school: ‘Practice two things in your dealings with disease: either help or do not harm the patient.’ This was later simplified to the most basic precept of the Hippocratic Oath: ‘First, do no harm.’ It is one of the principal precepts of bioethics that all students in healthcare that, given an existing problem, it may be better not to do something, or even to do nothing, than to risk causing more harm than good. The development of neurotechnology could be subsumed with little modification under the Geneva formulation of the Hippocratic Oath, extending this precept to a commitment not to damage people’s psychological health.

Nowadays, physicalism is arguably the received view on the nature of mental states. Among the arguments that have been provided in its favour, the inductive one seems to play a pivotal role in the debate. Leveraging the past success of materialistic science, the physicalist argues that a materialistic account of consciousness will eventually be provided, hence that physicalism is true. This article aims at evaluating whether this strategy can provide support for physicalism. According to the standard objection raised against the (...) inductive line of reasoning, the argument would beg the question by assuming some sort of metaphysical uniformity between consciousness and the rest of the natural domain. Here, I concede that there is a way to avoid this criticism. However, I argue that the argument still fails to support physicalism due to a structural problem of justification transmission. (shrink)

The possibility of AI consciousness depends much on the correct answer to the mind–body problem: how our materialistic brain generates subjective consciousness? If a materialistic answer is valid, machine consciousness must be possible, at least in principle, though the actual instantiation of consciousness may still take a very long time. If a non-materialistic one (either mentalist or dualist) is valid, machine consciousness is much less likely, perhaps impossible, as some mental element may also be required. Some recent advances in neurology (...) (despite the separation of the two hemispheres, our brain as a whole is still able to produce only one conscious agent; the negation of the absence of a free will, previously thought to be established by the Libet experiments) and many results of parapsychology (on medium communications, memories of past lives, near-death experiences) suggestive of survival after our biological death, strongly support the non-materialistic position and hence the much lower likelihood of AI consciousness. Instead of being concern about AI turning conscious and machine ethics, and trying to instantiate AI consciousness soon, we should perhaps focus more on making AI less costly and more useful to society.

In a new study, Ben-Haim et al. use subliminal stimuli to separate conscious and unconscious perception in macaques. A programme of this type, using a range of cognitive tasks, is a promising way to look for conscious perception in more controversial cases.

The article deals with the problem of cognition in the framework of the biogenetic structuralist neurophenomenology of Charles Laughlin. The aim of the article is to study the possibilities of applying the biogenetic structuralist theory as a theoretical and methodological basis for the study of consciousness in Laughlin’s theory. A feature of biogenetic structuralism is the interdisciplinary fusion of anthropology, psychology, and neuroscience. The methodology of biogenetic structuralism allows exploring universal structures of consciousness, which are caused by the genetically predisposed (...) organization of the human nervous system. Universal structures of consciousness include structures that mediate human language, knowledge of time and space. It is shown that the problem of cognition is realized in neurognostic models, which are compared with the operational environment. Neurognostic models include both the real nature of man as an organism and the external environment of the organism. Laughlin introduces the concept of a cognitive environment to designate a set of neurognostic models that can potentially be captured by the area of consciousness. He relies on the idea of a cognitive environment, which is essentially intentional in its organization. The polar interaction between the prefrontal cortex and the sensory cortex of the human brain gives rise to the intentionality of consciousness. Laughlin explains the work of the human cerebral cortex neurognostically as omnipresent for human consciousness, and independent of the cultural background. The cerebral cortex is a field of neural activity that arises and dissolves in temporal sequences and coordinates with cognitive processes that connect meaning and form into a single structure in consciousness. The experience of consciousness suggests a sensitive sphere of the cerebral cortex ascertains the meaningful, phenomenal world. The biogenetic structuralist methodology allows to development of an idea of the intentional structure and uniqueness of consciousness. The biogenetic structuralist approach is heuristic for modern science because, firstly, this approach creates the maximum opportunity to include data obtained from naturalistic, ethnographic, anatomical, clinical, and experimental sources; secondly, biogenetic data have the widest empirical and phenomenological rationale; thirdly, biogenetic concepts are defined in the context of a holistic understanding of the phenomenon through the uniqueness of consciousness.

Changes that occurred in science in the second half of the twentieth century, led to the emergence of a number of Sciences, the subject of study of which requires the involvement of interdisciplinary methodology and theory of neuroscience, for example, neurobiology, neurolinguistics, neuroanthropology, neurophilosophy, neurophenomenology, etc. One of the features of modern anthropology is that the subject of its research involves an interdisciplinary dialogue, the involvement of methods and theories of socio-human and natural Sciences, which led to the formation of (...) neuroanthropology as a science. One of the trends in the development of neuroanthropological theory is the introduction of biogenetic structuralism in the field of research. The article is devoted to the analysis of the biogenetic structuralism as an example of an interdisciplinary dialogue in which transpersonal and phenomenological approaches are integrated in neuroanthropology. Appeal to the main areas ofneuroanthropologic research allows going beyond the framework of Cartesian dualism and considering issues of the relationship between body and mind in terms of an integrative approach. The biogenetic structuralist neurophenomenological theory is of great importance as a theoretical and methodological basis for cross-cultural studies of consciousness. (shrink)

In this chapter, I aim to examine the two central properties that are said to underlie the theory of mirror neurons, namely action execution and action observation. I shall call these the functional properties of mirror neurons. I will argue that attributing the functional properties of mirror cognition, as many neuroscientists do, to the so-called ‘mirror neurons’ suffers from the problem of misidentification. This is the problem of incorrectly identifying an object or a property of one sort with some other (...) object or property. In light of this, I will propose that the most promising solution for the problem of misidentification is to ground the functional properties of mirror neurons squarely in consciousness and its bearer.

“What is consciousness?” “What is the relationship between consciousness and the world?” Contemporary consciousness studies are dominated by a neurocentric paradigm that tends to reduce our mind to a mere product of the brain, thus impeding the complete understanding of the multifaceted nature of consciousness. It is therefore necessary to change the direction of research, focusing no more on the isolated brain or on the disembodied mind, rather on an interdisciplinary and nonreductive approach to experience that intertwines philosophy, phenomenology, and (...) neuroscience. This neurophilosophical and neuroethical perspective will reconsider consciousness not merely in terms of the brain- or mind-relationship, but as intrinsically world-related. (shrink)

Philosophers of mind have been arguing for decades about the nature of phenomenal consciousness and the relation between brain and mind. More recently, neuroscientists and philosophers of science have entered the discussion. Which neural activities in the brain constitute phenomenal consciousness, and how could science distinguish the neural correlates of consciousness from its neural constitution? At what level of neural activity is consciousness constituted in the brain and what might be learned from well-studied phenomena like binocular rivalry, attention, memory, affect, (...) pain, dreams and coma? What should the science of consciousness want to know and what should explanation look like in this field? How should the constitution relation be applied to brain and mind and are other relations like identity, supervenience, realization, emergence and causation preferable? Building on a companion volume on the constitution of visual consciousness, this volume addresses these questions and related empirical and conceptual territory. It brings together, for the first time, scientists and philosophers to discuss this engaging interdisciplinary topic. (shrink)

What is consciousness? Although some philosophical approaches propose that could be some kind of emergent property of matter, the integration of different neurobiological and psychological evidence allow us to suggest that there is a simpler explanation: consciousness is an inescapable loop of stimuliresponse, a process that brains with very specific characteristics do. Through the integration of the theoretical frameworks of the Neurobiological Naturalism, the Two-Stage Model of perception and the Neuronal Global Workspace, the INMC tries to support the scientific conceptualization (...) of consciousness and its ethical, physicalist and non-anthropocentric approach.

BackgroundSevere brain injury is a leading cause of death and disability. Diagnosis and prognostication are difficult, and errors occur often. Novel neuroimaging methods can improve diagnostic and prognostic accuracy, especially in patients with prolonged disorders of consciousness. Yet it is currently unknown how family caregivers understand this information, raising ethical concerns that disclosure of neuroimaging results could result in therapeutic misconception or false hope.MethodsTo examine these ethical concerns, we conducted semi-structured interviews with caregivers of patients with PDoC who were enrolled (...) in a concurrent neuroimaging research program designed to detect covert consciousness following severe brain injury. Caregivers held surrogate decision-making status for a patient. Interviews were conducted at two time points for each caregiver. The first interview occurred before the disclosure of neuroimaging results. The second occurred after disclosure. Descriptive analysis was applied to the data of four interview topics: expectations for neuroimaging; reactions to evidence of preserved cognition; reactions to null results; and understanding of the results and study.ResultsTwelve caregivers participated in the study; two caregivers shared surrogate decision-making status for one patient with PDoC. Twenty-one interviews were completed; one caregiver declined to participate in the post-disclosure interview. Three patients with PDoC associated with the study displayed evidence of covert consciousness. Overall, caregivers understood the neuroimaging research and results. Caregivers who received results of covert consciousness were generally pleased. However, there was some variation in expectations and reactions to these data and null results.ConclusionThis study, for the first time, reveals caregiver expectations for and reactions to neuroimaging evidence of covert consciousness in patients with PDoC. Caregivers understood the neuroimaging research and results, casting doubt on speculative ethical concerns regarding therapeutic misconception and false hope. However, disclosure of neuroimaging result could be improved. Pre-disclosure consultations might assist professionals in shaping caregiver expectations. Standardization of disclosure might also improve comprehension of the results. (shrink)

X and X articulate, and, therefore, conserve, an uber-simple, circle. Providing the background (and the foreground) for everything (Nature) (reality).

Our access to computer-generated worlds changes the way we feel, how we think, and how we solve problems. In this review, we explore the utility of different types of virtual reality, immersive or non-immersive, for providing controllable, safe environments that enable individual training, neurorehabilitation, or even replacement of lost functions. The neurobiological effects of virtual reality on neuronal plasticity have been shown to result in increased cortical gray matter volumes, higher concentration of electroencephalographic beta-waves, and enhanced cognitive performance. Clinical application (...) of virtual reality is aided by innovative brain-computer interfaces, which allow direct tapping into the electric activity generated by different brain cortical areas for precise voluntary control of connected robotic devices. Virtual reality is also valuable to healthy individuals as a narrative medium for redesigning their individual stories in an integrative process of self-improvement and personal development. Future upgrades of virtual reality-based technologies promise to help humans transcend the limitations of their biological bodies and augment their capacity to mold physical reality to better meet the needs of a globalized world.

This paper argues that severe and ongoing trauma (SOT) can lead to impairment at the level of the minimal self (MS), which is the core element in the structure of subjectivity. In the long-term, such impairments can result in complex post-traumatic stress disorder (CPTSD) and schizophrenia. The paper tackles this issue while trying to create meaningful bridges between phenomenology and neuroscience.

Uncovering the neural basis of consciousness is a major challenge to neuroscience. In this Perspective, Tononi and colleagues describe the integrated information theory of consciousness and how it might be used to answer outstanding questions about the nature of consciousness.

When does a human being cease to exist? For millennia, the answer to this question had remained largely unchanged: death had been diagnosed when heartbeat and breathing were permanently absent. Only comparatively recently, in the 1950s, rapid developments in intensive-care medicine called into question this widely accepted criterion. What had previously been deemed a permanent cessation of vital functions suddenly became reversible. -/- A new criterion of death was needed. It was suggested that the destruction of the brain could indicate (...) the death of the organism in the presence of external life support. Soon the so-called brain death became the new worldwide standard. In recent years, however, doubts about this neurological criterion have been growing. Is brain death really our death? -/- This is the question that this thesis seeks to answer. To this end, we shall connect the medical debate about the definition of death to the philosophical debate about personal identity. While we will find that the destruction of its brain does in fact not correspond to an organism’s death, we shall also ask whether the assumption that we are essentially organisms is correct. May brain death be the ceasing to exist of a different entity? -/- Substituting clinical case reports and considerations about human physiology for the use of thought experiments, the thesis takes a novel and philosophically unconventional approach to the problem of what we essentially are. We shall analyse various pathological conditions and their respective effects on the bodily and mental characteristics of our existence. We will conclude that brain death is indeed our death – but for reasons entirely different from those cited in the original justification of this criterion. (shrink)
