It summarizes research on the neuroscience of consciousness, particularly from recent decades. Dehaene reviews historical intuitions that consciousness must be separate from matter.

During the last three decades our understanding of the brain processes underlying consciousness and attention has significantly improved, mainly because of the advances in functional neuroimaging techniques. Still, caution is needed for the correct interpretation of these empirical findings, as both research and theoretical proposals are hampered by a number of conceptual difficulties. We review some of the most significant theoretical issues concerning the concepts of consciousness and attention in the neuroscientific literature, and put forward the implications of these reflections for a coherent model of the neural correlates of these brain functions. Even though consciousness and attention have an overlapping pattern of neural activity, they should be considered as essentially separate brain processes.

The Neural Correlates of Consciousness and Attention: Two Sister Processes of the Brain

Cognition, Brain, and Consciousness, Second Edition , provides students and readers with an overview of the study of the human brain and its cognitive development. It discusses brain molecules and their primary function, which is to help carry brain signals to and from the different parts of the human body. These molecules are also essential for understanding language, learning, perception, thinking, and other cognitive functions of our brain. The book also presents the tools that can be used to view the human brain through brain imaging or recording. New to this edition are Frontiers in Cognitive Neuroscience text boxes, each one focusing on a leading researcher and their topic of expertise.

Conscious experience in humans depends on brain activity, so neuroscience will contribute to explaining consciousness. What would it be for neuroscience to explain consciousness? How much progress has neuroscience made in doing so? What challenges does it face? How can it meet those challenges? What is the philosophical significance of its findings? This entry addresses these and related questions.

This volume of essays examines the problem of mind, looking at how the problem has appeared to neuroscientists in the widest sense from classical antiquity through to contemporary times. The volume offers a chapter on the 19th century Ottoman perspective on western thinking. The book covers significant work from the twentieth century, including an examination of Alfred North Whitehead and the history of consciousness, and particular attention is given to the development of quantum consciousness. Chapters on slavery and the self and the development of an understanding of Dualism bring this examination up to date on the latest 21st century work in the field. At the heart of this book is the matter of how we define the problem of consciousness itself: has there been any progress in our understanding of the working of mind and brain?

Mind, Brain, and Consciousness: The Organization of Competence and Conduct

The Psychobiology of Consciousness pp Cite as. The history of psychology in this century can be charted in terms of the issue that dominated each decade of exploration. Early studies on classical conditioning and Gestalt principles of perception were followed subsequently by two decades of behaviorism. In the s information measurement took the stage to be supplanted in the s by an almost frenetic endeavor to catalogue memory processes, an endeavor which culminated in the new concepts of a cognitive psychology. Currently, the study of consciousness as central to the mind-brain problem has emerged from the explorations of altered and alternative states produced by drugs, meditation, and a variety of other techniques designed to promote psychological growth.

Look Inside. 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. It is essential reading for those who want to experience the excitement of the search for the mind in the brain.

Charles Siewert presents a distinctive approach to consciousness that emphasizes our first-person knowledge of experience and argues that we should grant consciousness, understood in this way, a central place in our conception of mind and intentionality. Written in an engaging manner that makes its recently controversial topic accessible to the thoughtful general reader, this book challenges theories that equate consciousness with a functional role or with the mere availability of sensory information to cognitive capacities. Siewert argues that the notion of phenomenal consciousness, slighted in some recent theories, can be made evident by noting our reliance on first-person knowledge and by considering, from the subject's point of view, the difference between having and lacking certain kinds of experience. This contrast is clarified by careful attention to cases, both actual and hypothetical, indicated by research on brain-damaged patients' ability to discriminate visually without conscious visual experience--what has become known as "blindsight. Experiences that are conscious in Siewert's sense differ from each other in ways that only what is conscious can--in phenomenal character--and having this character gives them intentionality.

Decoding the neuroscience of consciousness

How is consciousness created? When did it first appear on Earth, and how did it evolve? What constitutes consciousness, and which animals can be said to be sentient? In this book, Todd Feinberg and Jon Mallatt draw on recent scientific findings to answer these questions—and to tackle the most fundamental question about the nature of consciousness: how does the material brain create subjective experience?
