In the end, the author suggests that as more is learned about the working of the brain, philosophical problems that have caused centuries of speculation will simply be resolved by the facts of neurophysiology. --Book Jacket.
A leading neuroscientist explores with authority, with imagination, and with unparalleled mastery how the brain constructs the mind and how the brain makes that mind conscious. Antonio Damasio has spent the past thirty years researching and and revealing how the brain works. Here, in his most ambitious and stunning work yet, he rejects the long-standing idea that consciousness is somehow separate from the body, and presents compelling new scientific evidence that posits an evolutionary perspective. His view entails a radical change in the way the history of the conscious mind is viewed and told, suggesting that the brain’s development of a human self is a challenge to nature’s indifference. This development helps to open the way for the appearance of culture, perhaps one of our most defining characteristics as thinking and self-aware beings.
The problem of consciousness continues to be a subject of great debate in cognitive science. Synthesizing decades of research, The Conscious Brain advances a new theory of the psychological and neurophysiological correlates of conscious experience. Prinz's account of consciousness makes two main claims: first consciousness always arises at a particular stage of perceptual processing, the intermediate level, and, second, consciousness depends on attention. Attention changes the flow of information allowing perceptual information to access memory systems. Neurobiologically, this change in flow depends on synchronized neural firing. Neural synchrony is also implicated in the unity of consciousness and in the temporal duration of experience. Prinz also explores the limits of consciousness. We have no direct experience of our thoughts, no experience of motor commands, and no experience of a conscious self. All consciousness is perceptual, and it functions to make perceptual information available to systems that allows for flexible behavior. Prinz concludes by discussing prevailing philosophical puzzles. He provides a neuroscientifically grounded response to the leading argument for dualism, and argues that materialists need not choose between functional and neurobiological approaches, but can instead combine these into neurofunctional response to the mind-body problem. The Conscious Brain brings neuroscientific evidence to bear on enduring philosophical questions, while also surveying, challenging, and extending philosophical and scientific theories of consciousness. All readers interested in the nature of consciousness will find Prinz's work of great interest.
"Brain-Mind presents a unified, brain-based theory of cognition and emotion, with applications to the most complex kinds of thinking, right up to consciousness and creativity. Unification comes from systematic application of Chris Eliasmith's powerful new Semantic Pointer Architecture, a highly original synthesis of neural network and symbolic ideas about how the mind works. Thagard will show the relevance of semantic pointers to a full range of important kinds of mental representations, from sensations and imagery to concepts, rules, analogies, and emotions. Neural mechanisms can then be used to explain many phenomena concerning consciousness, action, intention, language, creativity, and the self. Because of their broad importance, Thagard has tried to make Eliasmith's ideas accessible to a broad audience with no special background in neuroscience or mathematics. The value of a unified theory of thinking goes well beyond psychology, neuroscience, and the other cognitive sciences"--
What is consciousness and how can a brain, a mere collection of neurons, create it? In Consciousness and the Social Brain, Princeton neuroscientist Michael Graziano lays out an audacious new theory to account for the deepest mystery of them all. The human brain has evolved a complex circuitry that allows it to be socially intelligent. This social machinery has only just begun to be studied in detail. One function of this circuitry is to attribute awareness to others: to compute that person Y is aware of thing X. In Graziano's theory, the machinery that attributes awareness to others also attributes it to oneself. Damage that machinery and you disrupt your own awareness. Graziano discusses the science, the evidence, the philosophy, and the surprising implications of this new theory.
Alva Noë is one of a new breed—part philosopher, part cognitive scientist, part neuroscientist—who are radically altering the study of consciousness by asking difficult questions and pointing out obvious flaws in the current science. In Out of Our Heads, he restates and reexamines the problem of consciousness, and then proposes a startling solution: Do away with the two hundred-year-old paradigm that places consciousness within the confines of the brain. Our culture is obsessed with the brain—how it perceives; how it remembers; how it determines our intelligence, our morality, our likes and our dislikes. It's widely believed that consciousness itself, that Holy Grail of science and philosophy, will soon be given a neural explanation. And yet, after decades of research, only one proposition about how the brain makes us conscious—how it gives rise to sensation, feeling, and subjectivity—has emerged unchallenged: We don't have a clue. In this inventive work, Noë suggests that rather than being something that happens inside us, consciousness is something we do. Debunking an outmoded philosophy that holds the scientific study of consciousness captive, Out of Our Heads is a fresh attempt at understanding our minds and how we interact with the world around us.
A highly original theory of how the mind-brain works, based on the author's study of single neuronal cells. In I of the Vortex, Rodolfo Llinas, a founding father of modern brain science, presents an original view of the evolution and nature of mind. According to Llinas, the "mindness state" evolved to allow predictive interactions between mobile creatures and their environment. He illustrates the early evolution of mind through a primitive animal called the "sea squirt." The mobile larval form has a brainlike ganglion that receives sensory information about the surrounding environment. As an adult, the sea squirt attaches itself to a stationary object and then digests most of its own brain. This suggests that the nervous system evolved to allow active movement in animals. To move through the environment safely, a creature must anticipate the outcome of each movement on the basis of incoming sensory data. Thus the capacity to predict is most likely the ultimate brain function. One could even say that Self is the centralization of prediction. At the heart of Llinas's theory is the concept of oscillation. Many neurons possess electrical activity, manifested as oscillating variations in the minute voltages across the cell membrane. On the crests of these oscillations occur larger electrical events that are the basis for neuron-to-neuron communication. Like cicadas chirping in unison, a group of neurons oscillating in phase can resonate with a distant group of neurons. This simultaneity of neuronal activity is the neurobiological root of cognition. Although the internal state that we call the mind is guided by the senses, it is also generated by the oscillations within the brain. Thus, in a certain sense, one could say that reality is not all "out there," but is a kind of virtual reality.
INTERNATIONAL BESTSELLER A Best Book of 2021—Bloomberg Businessweek; A Best Science Book of 2021—The Guardian; A Best Science Book of 2021—Financial Times; A Best Philosophy Book of 2021—Five Books; A Best Book of 2021—The Economist Anil Seth's quest to understand the biological basis of conscious experience is one of the most exciting contributions to twenty-first-century science. What does it mean to “be you”—that is, to have a specific, conscious experience of the world around you and yourself within it? There may be no more elusive or fascinating question. Historically, humanity has considered the nature of consciousness to be a primarily spiritual or philosophical inquiry, but scientific research is now mapping out compelling biological theories and explanations for consciousness and selfhood. Now, internationally renowned neuroscience professor, researcher, and author Anil Seth is offers a window into our consciousness in BEING YOU: A New Science of Consciousness. Anil Seth is both a leading expert on the neuroscience of consciousness and one of most prominent spokespeople for this relatively new field of science. His radical argument is that we do not perceive the world as it objectively is, but rather that we are prediction machines, constantly inventing our world and correcting our mistakes by the microsecond, and that we can now observe the biological mechanisms in the brain that accomplish this process of consciousness. Seth has been interviewed for documentaries aired on the BBC, Netflix, and Amazon and podcasts by Sam Harris, Russell Brand, and Chris Anderson, and his 2017 TED Talk on the topic has been viewed over 11 million times, a testament to his uncanny ability to make unimaginably complex science accessible and entertaining.
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.
How consciousness appeared much earlier in evolutionary history than is commonly assumed, and why all vertebrates and perhaps even some invertebrates are conscious. 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? After assembling a list of the biological and neurobiological features that seem responsible for consciousness, and considering the fossil record of evolution, Feinberg and Mallatt argue that consciousness appeared much earlier in evolutionary history than is commonly assumed. About 520 to 560 million years ago, they explain, the great “Cambrian explosion” of animal diversity produced the first complex brains, which were accompanied by the first appearance of consciousness; simple reflexive behaviors evolved into a unified inner world of subjective experiences. From this they deduce that all vertebrates are and have always been conscious—not just humans and other mammals, but also every fish, reptile, amphibian, and bird. Considering invertebrates, they find that arthropods (including insects and probably crustaceans) and cephalopods (including the octopus) meet many of the criteria for consciousness. The obvious and conventional wisdom–shattering implication is that consciousness evolved simultaneously but independently in the first vertebrates and possibly arthropods more than half a billion years ago. Combining evolutionary, neurobiological, and philosophical approaches allows Feinberg and Mallatt to offer an original solution to the “hard problem” of consciousness.
