Book excerpt: One of the nation's leading neuroscientists presents a radically new view of the function of the brain and the nervous system. Its central idea is that the nervous system in each individual operates as a selective system resembling natural selection in evolution, but operating by different mechanisms. This far-ranging theory of brain functions is bound to stimulate renewed discussion of such philosophical issues as the mind-body problem, the origins of knowledge and the perceptual bases of language. Notes and Index.

Available in PDF, EPUB and Kindle. Book excerpt: Burgeoning advances in brain science are opening up new perspectives on how we acquire knowledge. Indeed, it is now possible to explore consciousness - the very centre of human concern - by scientific means. In this illuminating book, Dr. Gerald M. Edelman offers a new theory of knowledge based on striking scientific findings about how the brain works. And he addresses the related compelling question: does the latest research imply that all knowledge can be reduced to scientific description? Edelman's brain-based approach to knowledge has rich implications for our understanding of creativity, of the normal and abnormal functioning of the brain, and of the connections among the different ways we have of knowing. While the gulf between science and the humanities and their respective views of the world has seemed enormous in the past, the author shows that their differences can be dissolved by considering their origins in brain functions. He foresees a day when brain-based devices will be conscious, and he reflects on this and other fascinating ideas about how we come to know the world and ourselves.
Download or read book The Neural Basis of Free Will written by Peter Tse and published by MIT Press. This book was released on 2013 with total page 473 pages. Available in PDF, EPUB and Kindle. Book excerpt: The issues of mental causation, consciousness, and free will have vexed philosophers since Plato. This book examines these unresolved issues from a neuroscientific perspective. In contrast with philosophers who use logic rather than data to argue whether mental causation or consciousness can exist given unproven first assumptions, Tse proposes that we instead listen to what neurons have to say. Because the brain must already embody a solution to the mind--body problem, why not focus on how the brain actually realizes mental causation? Tse draws on exciting recent neuroscientific data concerning how informational causation is realized in physical causation at the level of NMDA receptors, synapses, dendrites, neurons, and neuronal circuits. He argues that a particular kind of strong free will and downward mental causation are realized in rapid synaptic plasticity. Recent neurophysiological breakthroughs reveal that neurons function as criterial assessors of their inputs, which then change the criteria that will make other neurons fire in the future. Such informational causation cannot change the physical basis of information realized in the present, but it can change the physical basis of information that may be realized in the immediate future. This gets around the standard argument against free will centered on the impossibility of self-causation. Tse explores the ways that mental causation and qualia might be realized in this kind of neuronal and associated information-processing architecture, and considers the psychological and philosophical implications of having such an architecture realized in our brains.

Download or read book Discovering the Brain written by National Academy of Sciences and published by National Academies Press. This book was released on 1992-01-01 with total page 195 pages. Available in PDF, EPUB and Kindle. Book excerpt: The brain ... There is no other part of the human anatomy that is so intriguing. How does it develop and function and why does it sometimes, tragically, degenerate? The answers are complex. In Discovering the Brain, science writer Sandra Ackerman cuts through the complexity to bring this vital topic to the public. The 1990s were declared the "Decade of the Brain" by former President Bush, and the neuroscience community responded with a host of new investigations and conferences. Discovering the Brain is based on the Institute of Medicine conference, Decade of the Brain: Frontiers in Neuroscience and Brain Research. Discovering the Brain is a "field guide" to the brainâ€"an easy-to-read discussion of the brain's physical structure and where functions such as language and music appreciation lie. Ackerman examines: How electrical and chemical signals are conveyed in the brain. The mechanisms by which we see, hear, think, and pay attentionâ€"and how a "gut feeling" actually originates in the brain. Learning and memory retention, including parallels to computer memory and what they might tell us about our own mental capacity. Development of the brain throughout the life span, with a look at the aging brain. Ackerman provides an enlightening chapter on the connection between the brain's physical condition and various mental disorders and notes what progress can realistically be made toward the prevention and treatment of stroke and other ailments. Finally, she explores the potential for major advances during the "Decade of the Brain," with a look at medical imaging techniquesâ€"what various technologies can and cannot tell usâ€"and how the public and private sectors can contribute to continued advances in neuroscience. This highly readable volume will provide the public and policymakersâ€"and many scientists as wellâ€"with a helpful guide to understanding the many discoveries that are sure to be announced throughout the "Decade of the Brain."
Download or read book Body and Brain written by Dale Purves and published by Harvard University Press. This book was released on 1988 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: The major goal of developmental neurobiology is to understand how the nervous system is put together. A central theme that has emerged from research in this field over the last several decades is the crucial role of trophic interactions in neural assembly, and indeed throughout an animal's life. Trophic--which means nutritive--refers to long-term interdependencies between nerve cells and the cells they innervate. The theory of trophic effects presented in this book offers an explanation of how the vertebrate nervous system is related to--and regulated by--the body it serves. The theory rationalizes the nervous system's accommodation, throughout life, to the changing size and form of the body it tenants, indicating the way connections between nerve cells change in response to stimuli as diverse as growth, injury, experience, and natural selection. Dale Purves, a leading neurobiologist best known for his work on the formation and maintenance of synaptic connections, presents this theory within the historical setting of earlier ideas about neural organization--from Weiss's theory of functional reorganization to the chemoaffinity theory championed by Sperry. In addition to illuminating eighty years of work on trophic interactions, this book asks its own compelling questions: Are trophic interactions characteristic of all animals or only of those with complex nervous systems? Are trophic interactions related to learning? What does the trophic theory of neural connections imply about the currently fashionable view that the nervous system operates according to Darwinian principles? Purves lays the theoretical foundation for practical exploration of trophic interactions as they apply to neural connections, a pursuit that will help us understand how our own nervous systems generate change. The ideas in this book not only enrich neurobiology but also convey the profound relevance of neuroscience to other fields of life science.
Download or read book The Mindful Brain written by Gerald M. Edelman and published by MIT Press. This book was released on 1982-03-30 with total page 107 pages. Available in PDF, EPUB and Kindle. Book excerpt: A proposal by two eminent biological scientists for a mechanism whereby mind becomes manifest from the operations of brain tissue. This significant contribution to neuroscience consists of two papers, the first by Mountcastle an, the second by Edelman. Between them, they examine from different but complementary directions the relationships that connect the higher brain—memory, learning, perception, thinking—with what goes on at the most basic levels of neural activity, with particular stress on the role of local neuronal circuits.Edelman's major hypothesis is that "the conscious state results from phasic reentrant signaling occurring in parallel processes that involve associations between stored patterns and current sensory or internal input." This selective process occurs by the polling of degenerate primary repertoires of neuronal groups that are formed during embryogenesis and development. Edelman's theory extrapolates to the brain the selectionistic immunological theories for which he was awarded the 1972 Nobel Prize in Physiology or Medicine. Mountcastle's paper reviews what is known about the actual structure of various parts of the neo cortex. He relates the large entities of the neocortex to their component modules—the local neuronal circuits—and shows how the complex interrelationships of such a distributed system can yield dynamic distributed functioning. There are strong conceptual parallels between Mountcastle's idea of cortical columns and their functional subunits and Edelman's concept of populations of neurons functioning as processors in a brain system based on selectional rather than instructional principles. These parallels are traced and put into perspective in Francis Schmitt's Introduction.

Download or read book The Seductions of Darwin written by Matthew Rampley and published by Penn State Press. This book was released on 2017-01-12 with total page 201 pages. Available in PDF, EPUB and Kindle. Book excerpt: The surge of evolutionary and neurological analyses of art and its effects raises questions of how art, culture, and the biological sciences influence one another, and what we gain in applying scientific methods to the interpretation of artwork. In this insightful book, Matthew Rampley addresses these questions by exploring key areas where Darwinism, neuroscience, and art history intersect. Taking a scientific approach to understanding art has led to novel and provocative ideas about its origins, the basis of aesthetic experience, and the nature of research into art and the humanities. Rampley’s inquiry examines models of artistic development, the theories and development of aesthetic response, and ideas about brain processes underlying creative work. He considers the validity of the arguments put forward by advocates of evolutionary and neuroscientific analysis, as well as its value as a way of understanding art and culture. With the goal of bridging the divide between science and culture, Rampley advocates for wider recognition of the human motivations that drive inquiry of all types, and he argues that our engagement with art can never be encapsulated in a single notion of scientific knowledge. Engaging and compelling, The Seductions of Darwin is a rewarding look at the identity and development of art history and its complicated ties to the world of scientific thought.
Download or read book After Phrenology written by Michael L. Anderson and published by MIT Press. This book was released on 2014-12-12 with total page 411 pages. Available in PDF, EPUB and Kindle. Book excerpt: A proposal for a fully post-phrenological neuroscience that details the evolutionary roots of functional diversity in brain regions and networks. The computer analogy of the mind has been as widely adopted in contemporary cognitive neuroscience as was the analogy of the brain as a collection of organs in phrenology. Just as the phrenologist would insist that each organ must have its particular function, so contemporary cognitive neuroscience is committed to the notion that each brain region must have its fundamental computation. In After Phrenology, Michael Anderson argues that to achieve a fully post-phrenological science of the brain, we need to reassess this commitment and devise an alternate, neuroscientifically grounded taxonomy of mental function. Anderson contends that the cognitive roles played by each region of the brain are highly various, reflecting different neural partnerships established under different circumstances. He proposes quantifying the functional properties of neural assemblies in terms of their dispositional tendencies rather than their computational or information-processing operations. Exploring larger-scale issues, and drawing on evidence from embodied cognition, Anderson develops a picture of thinking rooted in the exploitation and extension of our early-evolving capacity for iterated interaction with the world. He argues that the multidimensional approach to the brain he describes offers a much better fit for these findings, and a more promising road toward a unified science of minded organisms.

Book excerpt: With New York Times bestselling author, Dr. Hanson's four steps, you can counterbalance your brain's negativity bias and learn to hardwire happiness in only a few minutes each day. Why is it easier to ruminate over hurt feelings than it is to bask in the warmth of being appreciated? Because your brain evolved to learn quickly from bad experiences and slowly from good ones, but you can change this. Life isn’t easy, and having a brain wired to take in the bad and ignore the good makes us worried, irritated, and stressed, instead of confident, secure, and happy. But each day is filled with opportunities to build inner strengths and Dr. Rick Hanson, an acclaimed clinical psychologist, shows what you can do to override the brain’s default pessimism. Hardwiring Happiness lays out a simple method that uses the hidden power of everyday experiences to build new neural structures full of happiness, love, confidence, and peace. You’ll learn to see through the lies your brain tells you. Dr. Hanson’s four steps build strengths into your brain to make contentment and a powerful sense of resilience the new normal. In just minutes a day, you can transform your brain into a refuge and power center of calm and happiness.
Download or read book Neural Networks and Animal Behavior written by Magnus Enquist and published by Princeton University Press. This book was released on 2005-09-04 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: How can we make better sense of animal behavior by using what we know about the brain? This is the first book that attempts to answer this important question by applying neural network theory. Scientists create Artificial Neural Networks (ANNs) to make models of the brain. These networks mimic the architecture of a nervous system by connecting elementary neuron-like units into networks in which they stimulate or inhibit each other's activity in much the same way neurons do. This book shows how scientists can employ ANNs to analyze animal behavior, explore the general principles of the nervous systems, and test potential generalizations among species. The authors focus on simple neural networks to show how ANNs can be investigated by math and by computers. They demonstrate intuitive concepts that make the operation of neural networks more accessible to nonspecialists. The first chapter introduces various approaches to animal behavior and provides an informal introduction to neural networks, their history, and their potential advantages. The second chapter reviews artificial neural networks, including biological foundations, techniques, and applications. The following three chapters apply neural networks to such topics as learning and development, classical instrumental condition, and the role of genes in building brain networks. The book concludes by comparing neural networks to other approaches. It will appeal to students of animal behavior in many disciplines. It will also interest neurobiologists, cognitive scientists, and those from other fields who wish to learn more about animal behavior.
