The Boundaries Of Consciousness Neurobiology And Neuropathology

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.

The second edition of The Neurology of Consciousness is a comprehensive update of this ground-breaking work on human consciousness, the first book in this area to summarize the neuroanatomical and functional underpinnings of consciousness by emphasizing a lesional approach offered by the study of neurological patients. Since the publication of the first edition in 2009, new methodologies have made consciousness much more accessible scientifically, and, in particular, the study of disorders, disruptions, and disturbances of consciousness has added tremendously to our understanding of the biological basis of human consciousness. The publication of a new edition is both critical and timely for continued understanding of the field of consciousness. In this critical and timely update, revised and new contributions by internationally renowned researchers—edited by the leaders in the field of consciousness research—provide a unique and comprehensive focus on human consciousness. The new edition of The Neurobiology of Consciousness will continue to be an indispensable resource for researchers and students working on the cognitive neuroscience of consciousness and related disorders, as well as for neuroscientists, psychologists, psychiatrists, and neurologists contemplating consciousness as one of the philosophical, ethical, sociological, political, and religious questions of our time. New chapters on the neuroanatomical basis of consciousness and short-term memory, and expanded coverage of comas and neuroethics, including the ethics of brain death The first comprehensive, authoritative collection to describe disorders of consciousness and how they are used to study and understand the neural correlates of conscious perception in humans. Includes both revised and new chapters from the top international researchers in the field, including Christof Koch, Marcus Raichle, Nicholas Schiff, Joseph Fins, and Michael Gazzaniga

By examining various aspects of human awareness, including the sense of touch, deafness and the constraints of language, this volume aims to define the essence of the material world in neurological rather than psychological or psychiatric terms.

A fascinating exploration of the nature of consciousness This engaging and readable book provides an introduction to consciousness that does justice both to the science and to the philosophy of consciousness, that is, the mechanics of the mind and the experience of awareness. The book opens with a general discussion of the brain and of consciousness itself. Then, exploring the areas of brain science most likely to illuminate the basis of awareness, Zeman focuses on the science of sleep and waking and on the science of vision. He describes healthy states and disorders--epilepsy, narcolepsy, blindsight and hallucinations after stroke--that provide insights into the capacity for consciousness and into its contents. And he tracks the evolution of the brain, the human species, and human culture and surveys the main current scientific theories of awareness, pioneering attempts to explain how the brain gives rise to experience. Zeman concludes by examining philosophical arguments about the nature of consciousness. A practicing neurologist, he animates his text with examples from the behavioral and neurological disorders of his patients and from the expanding mental worlds of young children, including his own. His book is an accessible and enlightening explanation of why we are conscious.

Consciousness is undoubtedly one of the last remaining scientific mysteries and hence one of the greatest contemporary scientific challenges. How does the brain's activity result in the rich phenomenology that characterizes our waking life? Are animals conscious? Why did consciousness evolve? How does science proceed to answer such questions? Can we define what consciousness is? Can we measure it? Can we use experimental results to further our understanding of disorders of consciousness, such as those seen in schizophrenia, delirium, or altered states of consciousness? These questions are at the heart of contemporary research in the domain. Answering them requires a fundamentally interdisciplinary approach that engages not only philosophers, but also neuroscientists and psychologists in a joint effort to develop novel approaches that reflect both the stunning recent advances in imaging methods as well as the continuing refinement of our concepts of consciousness. In this light, the Oxford Companion to Consciousness is the most complete authoritative survey of contemporary research on consciousness. Five years in the making and including over 250 concise entries written by leaders in the field, the volume covers both fundamental knowledge as well as more recent advances in this rapidly changing domain. Structured as an easy-to-use dictionary and extensively cross-referenced, the Companion offers contributions from philosophy of mind to neuroscience, from experimental psychology to clinical findings, so reflecting the profoundly interdisciplinary nature of the domain. Particular care has been taken to ensure that each of the entries is accessible to the general reader and that the overall volume represents a comprehensive snapshot of the contemporary study of consciousness. The result is a unique compendium that will prove indispensable to anyone interested in consciousness, from beginning students wishing to clarify a concept to professional consciousness researchers looking for the best characterization of a particular phenomenon.

This introduction to these and many of the other problems posed by consciousness discusses the most important work of cognitive science, neurophysiology and philosophy of the past thirty years and presents an up-to-date assessment of the issues and debates.

In this important and controversial new book, William Hirstein argues that it is possible for one person to directly experience the conscious states of another, by way of what he calls mindmelding. Drawing on a range of research from neuroscience, psychology, and philosophy, he presents a highly original new account of consciousness.
