The human brain is made up of 85 billion neurons, which are connected by over 100 trillion synapses. For more than a century, a diverse array of researchers searched for a language that could be used to capture the essence of what these neurons do and how they communicate – and how those communications create thoughts, perceptions and actions. The language they were looking for was mathematics, and we would not be able to understand the brain as we do today without it. In Models of the Mind, author and computational neuroscientist Grace Lindsay explains how mathematical models have allowed scientists to understand and describe many of the brain's processes, including decision-making, sensory processing, quantifying memory, and more. She introduces readers to the most important concepts in modern neuroscience, and highlights the tensions that arise when the abstract world of mathematical modelling collides with the messy details of biology. Each chapter of Models of the Mind focuses on mathematical tools that have been applied in a particular area of neuroscience, progressing from the simplest building block of the brain – the individual neuron – through to circuits of interacting neurons, whole brain areas and even the behaviours that brains command. In addition, Grace examines the history of the field, starting with experiments done on frog legs in the late eighteenth century and building to the large models of artificial neural networks that form the basis of modern artificial intelligence. Throughout, she reveals the value of using the elegant language of mathematics to describe the machinery of neuroscience.
This book is about the "neuroscience of you" and the mind-body connection. Starting with the evolution of awareness, the book will explain the theory of mind and how it relates to our ability to recognize ourselves in the mirror. In the second part, the book will discuss the philosophy of consciousness and how we could create consciousness with artificial intelligence. Who is this for? What is it about? What will it do for me? This book is for anyone interested in the inner mechanisms that make up "you", your consciousness, your perception of self, and your awareness. While it raises significant philosophic and scientific questions, it is an introductory book and can be read and understood by anyone new to the topic. The book explains how our brain evolved over millions of years, what damage to our brain can do to our conscious experience of the world, and how we could recreate human consciousness in a mechanical system. For you, the reader, the book will provide you with a new perspective on free will, consciousness, and philosophy. Imagine one of our ancestors in the distant past, sitting near a lake, lost in thought. She looks into the water and sees her reflection. Then, for the first time in the evolutionary history of humans, the question is asked, "What is this experience I have of myself?" Unbeknownst to her, that question would vex humanity through modern times. Today, there is again an entity looking into a proverbial lake and examining its reflection: while artificial intelligence is still in its infancy, it is on the verge of recognizing itself and asking the same question, "Who am I?" The closer we come to a machine that seems to be as intelligent as a human being, the more we start to worry about our own subjective experience. If a computer eventually becomes indistinguishable from us, what makes humans special? What is our role in the universe if we are so similar to a computer program? Does your brain need "you" at all? In this book, I will examine, from the ground up, questions about consciousness. Many steps toward the understanding of the self will tell you nothing about the self—until your right hemisphere connects everything into one idea as you understand the concept. Such an insight is also called an epiphany. Using a brain scanner, we can actually observe someone having an epiphany when the brain's right hemisphere suddenly buzzes with activity. While the left hemisphere deals with concrete entities, the right hemisphere helps with looking for alternative meanings. For example, the left hemisphere might identify a "bank" as a financial institution, while the right hemisphere also considers it to be the edge of a river ("riverbank"). In the Old Indo-Aryan language Sanskrit, an epiphany leading you to the answer about who you are is called "bodhi," which literally means "awakening" or "enlightenment." Similarly, the name "Buddha" means the "Awakened One" or the "Enlightened One." A similar idea can be found in Zen Buddhism as Satori which corresponds to a very sudden insight. This book shows some of the steps leading to Satori, combining the insights of philosophers and scientists into a new idea of what the "self" means. With this knowledge, we can better reflect on our own values and act according to reality rather than just blindly following someone else's beliefs. My goal with the book is to give you an introduction to neuroscience that is not scattered into different parts. I aim to focus on helping you to answer the following questions: What is the self? Does your brain even need a "self"? Is there a consciousness beyond the body? What is this seemingly mysterious subjective experience we share? How can we think, dream, plan, feel, and make decisions?
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.
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.
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.
Establishing the parameters and goals of the new field of mind, brain, and education science. A groundbreaking work, Mind, Brain, and Education Science explains the new transdisciplinary academic field that has grown out of the intersection of neuroscience, education, and psychology. The trend in “brain-based teaching” has been growing for the past twenty years and has exploded in the past five to become the most authoritative pedagogy for best learning results. Aimed at teachers, teacher trainers and policy makers, and anyone interested in the future of education in America and beyond, Mind, Brain, and Education Science responds to the clamor for help in identifying what information could and should apply in classrooms with confidence, and what information is simply commercial hype. Combining an exhaustive review of the literature, as well as interviews with over twenty thought leaders in the field from six different countries, this book describes the birth and future of this new and groundbreaking discipline. Mind, Brain, and Education Science looks at the foundations, standards, and history of the field, outlining the ways that new information should be judged. Well-established information is elegantly separated from “neuromyths” to help teachers split the wheat from the chaff in classroom planning, instruction and teaching methodology.
Is there a theory that explains the essence of consciousness? Or is consciousness itself an illusion? Am I conscious now? Now considered the 'last great mystery of science', consciousness was once viewed with extreme scepticism and rejected by mainstream scientists. It is now a significant area of research, albeit a contentious one, as well as a rapidly expanding area of study for students of psychology, philosophy, and neuroscience. This edition of Consciousness, revised by author team Susan Blackmore and Emily Troscianko, explores the key theories and evidence in consciousness studies ranging from neuroscience and psychology to quantum theories and philosophy. It examines why the term ‘consciousness’ has no recognised definition and provides an opportunity to delve into personal intuitions about the self, mind, and consciousness. Featuring comprehensive coverage of all core topics in the field, this edition includes: Why the problem of consciousness is so hard Neuroscience and the neural correlates of consciousness Why we might be mistaken about our own minds The apparent difference between conscious and unconscious Theories of attention, free will, and self and other The evolution of consciousness in animals and machines Altered states from meditation to drugs and dreaming Complete with key concept boxes, profiles of well-known thinkers, and questions and activities suitable for both independent study and group work, Consciousness provides a complete introduction to this fascinating field.

BRILLIANTLY EXPLORING TODAY'S CUTTING-EDGE BRAIN RESEARCH, MIND WIDE OPEN IS AN UNPRECEDENTED JOURNEY INTO THE ESSENCE OF HUMAN PERSONALITY, ALLOWING READERS TO UNDERSTAND THEMSELVES AND THE PEOPLE IN THEIR LIVES AS NEVER BEFORE. Using a mix of experiential reportage, personal storytelling, and fresh scientific discovery, Steven Johnson describes how the brain works -- its chemicals, structures, and subroutines -- and how these systems connect to the day-to-day realities of individual lives. For a hundred years, he says, many of us have assumed that the most powerful route to self-knowledge took the form of lying on a couch, talking about our childhoods. The possibility entertained in this book is that you can follow another path, in which learning about the brain's mechanics can widen one's self-awareness as powerfully as any therapy or meditation or drug. In Mind Wide Open, Johnson embarks on this path as his own test subject, participating in a battery of attention tests, learning to control video games by altering his brain waves, scanning his own brain with a $2 million fMRI machine, all in search of a modern answer to the oldest of questions: who am I? Along the way, Johnson explores how we "read" other people, how the brain processes frightening events (and how we might rid ourselves of the scars those memories leave), what the neurochemistry is behind love and sex, what it means that our brains are teeming with powerful chemicals closely related to recreational drugs, why music moves us to tears, and where our breakthrough ideas come from. Johnson's clear, engaging explanation of the physical functions of the brain reveals not only the broad strokes of our aptitudes and fears, our skills and weaknesses and desires, but also the momentary brain phenomena that a whole human life comprises. Why, when hearing a tale of woe, do we sometimes smile inappropriately, even if we don't want to? Why are some of us so bad at remembering phone numbers but brilliant at recognizing faces? Why does depression make us feel stupid? To read Mind Wide Open is to rethink family histories, individual fates, and the very nature of the self, and to see that brain science is now personally transformative -- a valuable tool for better relationships and better living.
The Cambridge Handbook of Consciousness is the first of its kind in the field, and its appearance marks a unique time in the history of intellectual inquiry on the topic. After decades during which consciousness was considered beyond the scope of legitimate scientific investigation, consciousness re-emerged as a popular focus of research towards the end of the last century, and it has remained so for nearly 20 years. There are now so many different lines of investigation on consciousness that the time has come when the field may finally benefit from a book that pulls them together and, by juxtaposing them, provides a comprehensive survey of this exciting field. An authoritative desk reference, which will also be suitable as an advanced textbook.
