Book Description
This book brings together an international group of neuroscientists and philosophers who are investigating how the content of subjective experience is correlated with events in the brain. The fundamental methodological problem in consciousness research is the subjectivity of the target phenomenon--the fact that conscious experience, under standard conditions, is always tied to an individual, first-person perspective. The core empirical question is whether and how physical states of the human nervous system can be mapped onto the content of conscious experience. The search for the neural correlates of consciousness (NCC) has become a highly active field of investigation in recent years. Methods such as single-cell recording in monkeys and brain imaging and electrophysiology in humans, applied to such phenomena as blindsight, implicit/explicit cognition, and binocular rivalry, have generated a wealth of data. The same period has seen the development of a number of theories about NCC location. This volume brings together the leading experimentalists and theoreticians in the field. Topics include foundational and evolutionary issues, global integration, vision, consciousness and the NMDA receptor complex, neuroimaging, implicit processes, intentionality and phenomenal volition, schizophrenia, social cognition, and the phenomenal self. Contributors Jackie Andrade, Ansgar Beckermann, David J. Chalmers, Francis Crick, Antonio R. Damasio, Gerald M. Edelman, Dominic ffytche, Hans Flohr, N.P. Franks, Vittorio Gallese, Melvyn A. Goodale, Valerie Gray Hardcastle, Beena Khurana, Christof Koch, W.R. Lieb, Erik D. Lumer, Thomas Metzinger, Kelly J. Murphy, Romi Nijhawan, Joëlle Proust, Antti Revonsuo, Gerhard Roth, Thomas Schmidt, Wolf Singer, Giulio Tononi

Book Description
Drawing on neuroscientific research and metacognitive theory, this groundbreaking volume examines the theoretical implications that are elicited when neural correlates of consciousness (NCC) are identified. The relationship between consciousness and the brain has concerned philosophers for centuries, yet a tacit assumption in much empirically minded consciousness research seems to be that if we can only develop a map of correlations, no further questions remain to be asked. Beyond Neural Correlates of Consciousness starts where others stop, by asking what these correlations may tell us about the nature of consciousness. The book contains chapters considering the upshots of finding the neural correlates of consciousness in light of the most prominent contemporary theories in the field. This illuminates the theoretical consequences of succeeding in the quest for the neural correlates of consciousness from the perspective of global workspace theory, higher-order thought theory, local recurrency theory, and REFCON models, in addition to considering how this quest is shaped by different conscious phenomena, such as dreaming, altered states of consciousness, and different levels of consciousness. This insightful text features sophisticated theories that goes beyond correlational inferences and neural mapping, and will be of interest to students and researchers of consciousness, particularly those interested in interpreting neural correlates.

Book Description
This pioneering book explores in depth the role of neurotransmitters in conscious awareness. The central aim is to identify common neural denominators of conscious awareness, informed by the neurochemistry of natural, drug induced and pathological states of consciousness. Chemicals such as acetylcholine and dopamine, which bridge the synaptic gap between neurones, are the 'neurotransmitters in mind' that form the substance of the volume, which is essential reading for all who believe that unravelling mechanisms of consciousness must include these vital systems of the brain.Up-to-date information is provided on: Psychological domains of attention, motivation, memory, sleep and dreaming that define normal states of consciousness. Effects of chemicals that alter or abolish consciousness, including hallucinogens and anaesthetics. Disorders of the brain such as dementia, schizophrenia and depression considered from the novel perspective of the way these affect consciousness, and how this might relate to disturbances in neurotransmission.

Book Description
Consciousness is one of the most significant scientific problems today. Renewed interest in the nature of consciousness - a phenomenon long considered not to be scientifically explorable, as well as increasingly widespread availability of multimodal functional brain imaging techniques (EEG, ERP, MEG, fMRI and PET), now offer the possibility of detailed, integrated exploration of the neural, behavioral, and computational correlates of consciousness. The present volume aims to confront the latest theoretical insights in the scientific study of human consciousness with the most recent behavioral, neuroimaging, electrophysiological, pharmacological and neuropathological data on brain function in altered states of consciousness such as: brain death, coma, vegetative state, minimally conscious state, locked-in syndrome, dementia, epilepsy, schizophrenia, hysteria, general anesthesia, sleep, hypnosis, and hallucinations. The interest of this is threefold. First, patients with altered states of consciousness continue to represent a major clinical problem in terms of clinical assessment of consciousness and daily management. Second, the exploration of brain function in altered states of consciousness represents a unique lesional approach to the scientific study of consciousness and adds to the worldwide effort to identify the "neural correlate of consciousness". Third, new scientific insights in this field have major ethical and social implications regarding our care for these patients.

Book Description
A thought-provoking argument that consciousness—more widespread than previously assumed—is the feeling of being alive, not a type of computation or a clever hack In The Feeling of Life Itself, Christof Koch offers a straightforward definition of consciousness as any subjective experience, from the most mundane to the most exalted—the feeling of being alive. Psychologists study which cognitive operations underpin a given conscious perception. Neuroscientists track the neural correlates of consciousness in the brain, the organ of the mind. But why the brain and not, say, the liver? How can the brain—three pounds of highly excitable matter, a piece of furniture in the universe, subject to the same laws of physics as any other piece—give rise to subjective experience? Koch argues that what is needed to answer these questions is a quantitative theory that starts with experience and proceeds to the brain. In The Feeling of Life Itself, Koch outlines such a theory, based on integrated information. Koch describes how the theory explains many facts about the neurology of consciousness and how it has been used to build a clinically useful consciousness meter. The theory predicts that many, and perhaps all, animals experience the sights and sounds of life; consciousness is much more widespread than conventionally assumed. Contrary to received wisdom, however, Koch argues that programmable computers will not have consciousness. Even a perfect software model of the brain is not conscious. Its simulation is fake consciousness. Consciousness is not a special type of computation—it is not a clever hack. Consciousness is about being.

Book Description
A fascinating exploration of the human brain that combines “the leading edge of consciousness science with surprisingly personal and philosophical reflection . . . shedding light on how scientists really think”—this is “science writing at its best” (Times Higher Education). In which a scientist searches for an empirical explanation for phenomenal experience, spurred by his instinctual belief that life is meaningful. What links conscious experience of pain, joy, color, and smell to bioelectrical activity in the brain? How can anything physical give rise to nonphysical, subjective, conscious states? Christof Koch has devoted much of his career to bridging the seemingly unbridgeable gap between the physics of the brain and phenomenal experience. This engaging book—part scientific overview, part memoir, part futurist speculation—describes Koch’s search for an empirical explanation for consciousness. Koch recounts not only the birth of the modern science of consciousness but also the subterranean motivation for his quest—his instinctual (if “romantic”) belief that life is meaningful. Koch describes his own groundbreaking work with Francis Crick in the 1990s and 2000s and the gradual emergence of consciousness (once considered a “fringy” subject) as a legitimate topic for scientific investigation. Present at this paradigm shift were Koch and a handful of colleagues, including Ned Block, David Chalmers, Stanislas Dehaene, Giulio Tononi, Wolf Singer, and others. Aiding and abetting it were new techniques to listen in on the activity of individual nerve cells, clinical studies, and brain-imaging technologies that allowed safe and noninvasive study of the human brain in action. Koch gives us stories from the front lines of modern research into the neurobiology of consciousness as well as his own reflections on a variety of topics, including the distinction between attention and awareness, the unconscious, how neurons respond to Homer Simpson, the physics and biology of free will, dogs, Der Ring des Nibelungen, sentient machines, the loss of his belief in a personal God, and sadness. All of them are signposts in the pursuit of his life's work—to uncover the roots of consciousness.

Book Description
An argument for a Copernican revolution in our consideration of mental features—a shift in which the world-brain problem supersedes the mind-body problem. Philosophers have long debated the mind-body problem—whether to attribute such mental features as consciousness to mind or to body. Meanwhile, neuroscientists search for empirical answers, seeking neural correlates for consciousness, self, and free will. In this book, Georg Northoff does not propose new solutions to the mind-body problem; instead, he questions the problem itself, arguing that it is an empirically, ontologically, and conceptually implausible way to address the existence and reality of mental features. We are better off, he contends, by addressing consciousness and other mental features in terms of the relationship between world and brain; philosophers should consider the world-brain problem rather than the mind-body problem. This calls for a Copernican shift in vantage point—from within the mind or brain to beyond the brain—in our consideration of mental features. Northoff, a neuroscientist, psychiatrist, and philosopher, explains that empirical evidence suggests that the brain's spontaneous activity and its spatiotemporal structure are central to aligning and integrating the brain within the world. This spatiotemporal structure allows the brain to extend beyond itself into body and world, creating the “world-brain relation” that is central to mental features. Northoff makes his argument in empirical, ontological, and epistemic-methodological terms. He discusses current models of the brain and applies these models to recent data on neuronal features underlying consciousness and proposes the world-brain relation as the ontological predisposition for consciousness.

Book Description
It was not long ago when the consciousness was not considered a problem for science. However, this has now changed and the problem of consciousness is considered the greatest challenge to science. In the last decade, a great number of books and articles have been published in the field, but very few have focused on the how consciousness evolves and develops, and what characterizes the transitions between different conscious states, in animals and humans. This book addresses these questions. Renowned researchers from different fields of science (including neurobiology, evolutionary biology, ethology, cognitive science, computational neuroscience and philosophy) contribute with their results and theories in this book, making it a unique collection of the state-of-the-art of this young field of consciousness studies. First book on the topic Focus on different levels of consciousness, including: Evolutionary, developmental, and functional Highly interdisciplinary

Book Description
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 (AiCR 90), 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.
