While embracing the now classical theories of McCulloch and Pitts, the neuroidal model also accommodates state information in the neurons, more flexible timing mechanisms, a variety of assumptions about interconnectivity, and the possibility that different brain areas perform specialized functions. Programmable so that a wide range of algorithmic theories can be described and evaluated, the model provides a concrete computational language and a unified framework in which diverse cognitive phenomena - such as memory, learning, and reasoning - can be systematically and concurrently analyzed. Requiring no specialized knowledge, Circuits of the Mind masterfully offers an exciting new approach to brain science for students and researchers in computer science, neurobiology, neuroscience, artificial intelligence, and cognitive science.
Roger Sperry has made outstanding contributions to neuroscience. Here, he and over twenty of his contemporaries, review 50 years of both his work and their own in the context of Sperry's contribution to their fields. Sperry's challenging theories are still much alive in brain science, cognitive psychology and the philosophy of the mind.
This book covers recent advances in the understanding of brain structure, function and disorders based on the fundamental principles of physics. It covers a broad range of physical phenomena occurring in the brain circuits for perception, cognition, emotion and action, representing the building blocks of the mind. It provides novel insights into the devastating brain disorders of the mind such as schizophrenia, dementia, autism, aging or addictions, as well as into the new devices for brain repair. The book is aimed at basic researchers in the fields of neuroscience, physics, biophysics and clinicians in the fields of neurology, neurosurgery, psychology, psychiatry.
The authors review knowledge on the anatomy of the frontal-subcortical circuits, their connections to other brain regions, and their influences on motor, cognitive, affective, and behavioral functioning. Specific clinical problems are addressed, including Parkinson's disease, obsessive/compulsive disorder, ADHD, and more. of full-color illustrations.
The startling new science behind sudden acts of violence and the nine triggers this groundbreaking researcher has uncovered We all have a rage circuit we can’t fully control once it is engaged as R. Douglas Fields, PhD, reveals in this essential book for our time. The daily headlines are filled with examples of otherwise rational people with no history of violence or mental illness suddenly snapping in a domestic dispute, an altercation with police, or road rage attack. We all wish to believe that we are in control of our actions, but the fact is, in certain circumstances we are not. The sad truth is that the right trigger in the right circumstance can unleash a fit of rage in almost anyone. But there is a twist: Essentially the same pathway in the brain that can result in a violent outburst can also enable us to act heroically and altruistically before our conscious brain knows what we are doing. Think of the stranger who dives into a frigid winter lake to save a drowning child. Dr. Fields is an internationally recognized neurobiologist and authority on the brain and the cellular mechanisms of memory. He has spent years trying to understand the biological basis of rage and anomalous violence, and he has concluded that our culture’s understanding of the problem is based on an erroneous assumption: that rage attacks are the product of morally or mentally defective individuals, rather than a capacity that we all possess. Fields shows that violent behavior is the result of the clash between our evolutionary hardwiring and triggers in our contemporary world. Our personal space is more crowded than ever, we get less sleep, and we just aren't as fit as our ancestors. We need to understand how the hardwiring works and how to recognize the nine triggers. With a totally new perspective, engaging narrative, and practical advice, Why We Snap uncovers the biological roots of the rage response and how we can protect ourselves—and others.
In order to focus on principles, each chapter in this work is brief, organized around 1-3 wiring diagrams of the key circuits, with several pages of text that distil the functional significance of each microcircuit
Award Winner in the Science category of the 2020 Best Book Awards sponsored by American Book Fest Award-winning author and thought leader Dawson Church, Ph.D., blends cutting-edge neuroscience with intense firsthand experience to show you how you can rewire your brain for happiness-starting right now. Neural plasticity-the discovery that the brain is capable of rewiring itself-is now widely understood. But what few people have grasped yet is how quickly this is happening, how extensive brain changes can be, and how much control each of us has over the process. In Bliss Brain, famed researcher Dawson Church digs deep into leading-edge science, and finds stunning evidence of rapid and radical brain change. In just eight weeks of practice, 12 minutes a day, using the right techniques, we can produce measurable changes in our brains. These make us calmer, happier, and more resilient. When we cultivate these pleasurable states over time, they become traits. We don't just feel more blissful as a temporary state; the changes are literally hard-wired into our brains, becoming stable and enduring personality traits. The startling conclusions of Church's research show that neural remodeling goes much farther than scientists have previously understood, with stress circuits shriveling over time. Simultaneously, "The Enlightenment Circuit"-associated with happiness, compassion, productivity, creativity, and resilience-expands. During deep meditation, Church shows how "the 7 neurochemicals of ecstasy" are released in our brains. These include anandamide, a neurotransmitter that's been named "the bliss molecule" because it mimics the effects of THC, the active ingredient in cannabis. It boosts serotonin and dopamine; the first is an analog of psilocybin, the second of cocaine. He shows how cultivating these elevated emotional states literally produces a self-induced high. While writing Bliss Brain, Church went through a series of disasters, including escaping seconds ahead of a California wildfire that consumed his home and office and claimed 22 lives. The fire triggered a painful medical condition and a financial disaster. Through it all, Church steadily practiced the techniques of Bliss Brain while teaching them to thousands of other people. This book weaves his story of resilience into the fabric of neuroscience, producing a fascinating picture of just how happy we can make our brains, no matter what the odds.
Preeminent psychologist Lisa Barrett lays out how the brain constructs emotions in a way that could revolutionize psychology, health care, the legal system, and our understanding of the human mind. “Fascinating . . . A thought-provoking journey into emotion science.”—The Wall Street Journal “A singular book, remarkable for the freshness of its ideas and the boldness and clarity with which they are presented.”—Scientific American “A brilliant and original book on the science of emotion, by the deepest thinker about this topic since Darwin.”—Daniel Gilbert, best-selling author of Stumbling on Happiness The science of emotion is in the midst of a revolution on par with the discovery of relativity in physics and natural selection in biology. Leading the charge is psychologist and neuroscientist Lisa Feldman Barrett, whose research overturns the long-standing belief that emotions are automatic, universal, and hardwired in different brain regions. Instead, Barrett shows, we construct each instance of emotion through a unique interplay of brain, body, and culture. A lucid report from the cutting edge of emotion science, How Emotions Are Made reveals the profound real-world consequences of this breakthrough for everything from neuroscience and medicine to the legal system and even national security, laying bare the immense implications of our latest and most intimate scientific revolution.
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."
