Finding Consciousness In The Brain

How does the brain go about the business of being conscious? Though we cannot yet provide a complete answer, this book explains what is now known about the neural basis of human consciousness.The last decade has witnessed the dawn of an exciting new era of cognitive neuroscience. For example, combination of new imaging technologies and experimental study of attention has linked brain activity to specific psychological functions. The authors are leaders in psychology and neuroscience who have conducted original research on consciousness. They wish to communicate the highlights of this research to both specialists and interested others, and hope that this volume will be read by students concerned with the neuroscientific underpinnings of subjective experience. As a whole, the book progresses from an overview of conscious awareness, through careful explanation of identified neurocognitive systems, and extends to theories which tackle global aspects of consciousness.

WINNER OF THE 2014 BRAIN PRIZE From the acclaimed author of Reading in the Brain and How We Learn, 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.

From one of the world’s leading neuroscientists: a succinct, illuminating, wholly engaging investigation of how biology, neuroscience, psychology, and artificial intelligence have given us the tools to unlock the mysteries of human consciousness “One thrilling insight after another ... Damasio has succeeded brilliantly in narrowing the gap between body and mind.” —The New York Times Book Review In recent decades, many philosophers and cognitive scientists have declared the problem of consciousness unsolvable, but Antonio Damasio is convinced that recent findings across multiple scientific disciplines have given us a way to understand consciousness and its significance for human life. In the forty-eight brief chapters of Feeling & Knowing, and in writing that remains faithful to our intuitive sense of what feeling and experiencing are about, Damasio helps us understand why being conscious is not the same as sensing, why nervous systems are essential for the development of feelings, and why feeling opens the way to consciousness writ large. He combines the latest discoveries in various sciences with philosophy and discusses his original research, which has transformed our understanding of the brain and human behavior. Here is an indispensable guide to understand­ing how we experience the world within and around us and find our place in the universe.

Consciousness is our gateway to experience: it enables us to recognize Van Gogh’s starry skies, be enraptured by Beethoven’s Fifth, and stand in awe of a snowcapped mountain. Yet consciousness is subjective, personal, and famously difficult to examine: philosophers have for centuries declared this mental entity so mysterious as to be impenetrable to science. In The Ravenous Brain, neuroscientist Daniel Bor departs sharply from this historical view, and builds on the latest research to propose a new model for how consciousness works. Bor argues that this brain-based faculty evolved as an accelerated knowledge gathering tool. Consciousness is effectively an idea factory—that choice mental space dedicated to innovation, a key component of which is the discovery of deep structures within the contents of our awareness. This model explains our brains’ ravenous appetite for information—and in particular, its constant search for patterns. Why, for instance, after all our physical needs have been met, do we recreationally solve crossword or Sudoku puzzles? Such behavior may appear biologically wasteful, but, according to Bor, this search for structure can yield immense evolutionary benefits—it led our ancestors to discover fire and farming, pushed modern society to forge ahead in science and technology, and guides each one of us to understand and control the world around us. But the sheer innovative power of human consciousness carries with it the heavy cost of mental fragility. Bor discusses the medical implications of his theory of consciousness, and what it means for the origins and treatment of psychiatric ailments, including attention-deficit disorder, schizophrenia, manic depression, and autism. All mental illnesses, he argues, can be reformulated as disorders of consciousness—a perspective that opens up new avenues of treatment for alleviating mental suffering. A controversial view of consciousness, The Ravenous Brain links cognition to creativity in an ingenious solution to one of science’s biggest mysteries.

Synthesizing decades of research, this book advances a theory of the psychological and neurophysiological correlates of conscious experience. Prinz argues that consciousness always arises at a particular stage of perceptual processing, the intermediate level, and that consciousness depends on attention.

Modern medicine enables us to keep many people alive after they have suffered severe brain damage and show no reliable outward signs of consciousness. Many such patients are misdiagnosed as being in a permanent vegetative state when they are actually in a minimally conscious state. This mistake has far-reaching implications for treatment and prognosis. To alleviate this problem, neuroscientists have recently developed new brain-scanning methods to detect consciousness in some of these patients and even to ask them questions, including "Do you want to stay alive?" Finding Consciousness: The Neuroscience, Ethics, and Law of Severe Brain Damage addresses many questions regarding these recent neuroscientific methods: Is what these methods detect really consciousness? Do patients feel pain? Should we decide whether or not to let them die or are they competent to decide for themselves? And which kinds of treatment should governments and hospitals make available? This edited volume provides contextual information, surveys the issues and positions, and takes controversial stands from a wide variety of prominent contributors in fields ranging from neuroscience and neurology to law and policy to philosophy and ethics. Finding Consciousness should interest not only neuroscientists, clinicians, and ethicists but anyone who might suffer brain damage, which includes us all.

A bestselling author, neuroscientist, and computer engineer unveils a theory of intelligence that will revolutionize our understanding of the brain and the future of AI. For all of neuroscience's advances, we've made little progress on its biggest question: How do simple cells in the brain create intelligence? Jeff Hawkins and his team discovered that the brain uses maplike structures to build a model of the world—not just one model, but hundreds of thousands of models of everything we know. This discovery allows Hawkins to answer important questions about how we perceive the world, why we have a sense of self, and the origin of high-level thought. A Thousand Brains heralds a revolution in the understanding of intelligence. It is a big-think book, in every sense of the word.

“The father of cognitive neuroscience” illuminates the past, present, and future of the mind-brain problem How do neurons turn into minds? How does physical “stuff”—atoms, molecules, chemicals, and cells—create the vivid and various worlds inside our heads? The problem of consciousness has gnawed at us for millennia. In the last century there have been massive breakthroughs that have rewritten the science of the brain, and yet the puzzles faced by the ancient Greeks are still present. In The Consciousness Instinct, the neuroscience pioneer Michael S. Gazzaniga puts the latest research in conversation with the history of human thinking about the mind, giving a big-picture view of what science has revealed about consciousness. The idea of the brain as a machine, first proposed centuries ago, has led to assumptions about the relationship between mind and brain that dog scientists and philosophers to this day. Gazzaniga asserts that this model has it backward—brains make machines, but they cannot be reduced to one. New research suggests the brain is actually a confederation of independent modules working together. Understanding how consciousness could emanate from such an organization will help define the future of brain science and artificial intelligence, and close the gap between brain and mind. Captivating and accessible, with insights drawn from a lifetime at the forefront of the field, The Consciousness Instinct sets the course for the neuroscience of tomorrow.
