Book excerpt: Your brain is shrinking. Does it matter? Rethinking the Brain challenges us to explore how much brain we really need. Rather than just concentrating on the many wonderful things it can do, this entertaining insight into the complexities and contradictions of the human brain asks whether in fact we can live satisfactorily without some of it. The bad news is that our brains start to shrink from our mid-thirties. But the good news is that we still seem to generally muddle along and our brain is able to adapt in extraordinary ways when things go wrong. Alexis Willett and Jennifer Barnett shed light on what the human brain can do - in both optimal and suboptimal conditions - and consider what it can manage without. Through fascinating facts and figures, case studies and hypothetical scenarios, expert interviews and scientific principles, they take us on a journey from the ancient mists of time to the far reaches of the future, via different species and lands. Is brain training the key to healthy ageing? Do women really experience 'baby brain'? Is our brain at its evolutionary peak or do we have an even more brilliant future to look forward to? We discover the answers to these questions and more. Alexis Willett, PhD is a science communicator and specialist in biomedical science who spends much of her time turning cutting-edge research and health policy jargon into something meaningful for patients, doctors, policy makers and the public. Jennifer Barnett, PhD is a neuroscientist, psychologist and author working at the intersection of academic and industrial research into brain health and mental illness; designing new technologies to help detect, diagnose and treat brain disorders.

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."

Available in PDF, EPUB and Kindle. Book excerpt: People are endlessly fascinated with the brain and the mind - whether to seek greater understanding about themselves or those around them or to just marvel at the brain's intricacy and the many secrets it still seems to hold. This book takes a global view of the brain and its history and future, challenging us to think differently about the brain by focusing on one key question - How Much Brain Do We Really Need? The human brain is five times larger than would be expected for our body size. To allow for such a large brain, human babies must be born earlier than other species; defenceless and unable to feed themselves or even move out of harm's way. What evolutionary advantage does all this extra brain bring? Contrary to the popular myth, we do use more than ten percent of our brains, but even modern neuroscience cannot accurately tell us how much of our brain we use at any one time, or ever. Surprisingly large amounts of brain can be lost or damaged without losing functions like language, thinking, and emotions which seem to be the core of the human experience. Does this mean we don't really need all of our brain? The brain is the most complex system we know, a piece of hardware that trebles in size over the first year of birth and then constantly reshapes and reprograms at the microscopic level in response to every new life experience. Some experiences, like education, result in more neurons and a larger brain. With others, like drinking alcohol, heading a football, and in normal aging, cells die and cannot be replaced. People with larger brains function better on average, and they live longer. There is great variation within our species: men's brains are around 10% bigger than women's and people whose ancestors developed in colder climates tend to have a larger, rounder head and brain, in order to better conserve heat. The impact of these differences in 'hardware' is mitigated by differences in 'software': peak brain function depends not only on the size of the brain, but on how efficiently it is used. This book tackles many topical issues, such as whether brain training is the key to healthy ageing and whether new mums really experience the 'baby brain'. The authors examine evidence from evolution, development across the human lifespan, and medical reports of the effects of brain injuries, abnormal development, and degenerative diseases. They explore what normal variation in brain size and structure between the sexes, and within populations, means for the relationship between brain biology and intelligence and other cognitive functions. They also look to the future and ponder what the upper limit of human brain function might be, given optimal nutrition, education, medical care, and the ability to potentially replace or re-engineer faulty or aging brain cells.

Available in PDF, EPUB and Kindle. Book excerpt: First released in the Spring of 1999, How People Learn has been expanded to show how the theories and insights from the original book can translate into actions and practice, now making a real connection between classroom activities and learning behavior. This edition includes far-reaching suggestions for research that could increase the impact that classroom teaching has on actual learning. Like the original edition, this book offers exciting new research about the mind and the brain that provides answers to a number of compelling questions. When do infants begin to learn? How do experts learn and how is this different from non-experts? What can teachers and schools do-with curricula, classroom settings, and teaching methods--to help children learn most effectively? New evidence from many branches of science has significantly added to our understanding of what it means to know, from the neural processes that occur during learning to the influence of culture on what people see and absorb. How People Learn examines these findings and their implications for what we teach, how we teach it, and how we assess what our children learn. The book uses exemplary teaching to illustrate how approaches based on what we now know result in in-depth learning. This new knowledge calls into question concepts and practices firmly entrenched in our current education system. Topics include: How learning actually changes the physical structure of the brain. How existing knowledge affects what people notice and how they learn. What the thought processes of experts tell us about how to teach. The amazing learning potential of infants. The relationship of classroom learning and everyday settings of community and workplace. Learning needs and opportunities for teachers. A realistic look at the role of technology in education.

Book excerpt: We are profoundly social creatures--more than we know. In Social, renowned psychologist Matthew Lieberman explores groundbreaking research in social neuroscience revealing that our need to connect with other people is even more fundamental, more basic, than our need for food or shelter. Because of this, our brain uses its spare time to learn about the social world--other people and our relation to them. It is believed that we must commit 10,000 hours to master a skill. According to Lieberman, each of us has spent 10,000 hours learning to make sense of people and groups by the time we are ten. Social argues that our need to reach out to and connect with others is a primary driver behind our behavior. We believe that pain and pleasure alone guide our actions. Yet, new research using fMRI--including a great deal of original research conducted by Lieberman and his UCLA lab--shows that our brains react to social pain and pleasure in much the same way as they do to physical pain and pleasure. Fortunately, the brain has evolved sophisticated mechanisms for securing our place in the social world. We have a unique ability to read other people’s minds, to figure out their hopes, fears, and motivations, allowing us to effectively coordinate our lives with one another. And our most private sense of who we are is intimately linked to the important people and groups in our lives. This wiring often leads us to restrain our selfish impulses for the greater good. These mechanisms lead to behavior that might seem irrational, but is really just the result of our deep social wiring and necessary for our success as a species. Based on the latest cutting edge research, the findings in Social have important real-world implications. Our schools and businesses, for example, attempt to minimalize social distractions. But this is exactly the wrong thing to do to encourage engagement and learning, and literally shuts down the social brain, leaving powerful neuro-cognitive resources untapped. The insights revealed in this pioneering book suggest ways to improve learning in schools, make the workplace more productive, and improve our overall well-being.

Book excerpt: 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.

Book excerpt: This book reveals a remarkable paradox: what your brain wants is frequently not what your brain needs. In fact, much of what makes our brains "happy" leads to errors, biases, and distortions, which make getting out of our own way extremely difficult. Author David DiSalvo presents evidence from evolutionary and social psychology, cognitive science, neurology, and even marketing and economics. And he interviews many of the top thinkers in psychology and neuroscience today. From this research-based platform, DiSalvo draws out insights that we can use to identify our brains’ foibles and turn our awareness into edifying action. Ultimately, he argues, the research does not serve up ready-made answers, but provides us with actionable clues for overcoming the plight of our advanced brains and, consequently, living more fulfilled lives.

Available in PDF, EPUB and Kindle. Book excerpt: Neuroscience has made phenomenal advances over the past 50 years and the pace of discovery continues to accelerate. On June 25, 2008, the Institute of Medicine (IOM) Forum on Neuroscience and Nervous System Disorders hosted more than 70 of the leading neuroscientists in the world, for a workshop titled "From Molecules to Minds: Challenges for the 21st Century." The objective of the workshop was to explore a set of common goals or "Grand Challenges" posed by participants that could inspire and rally both the scientific community and the public to consider the possibilities for neuroscience in the 21st century. The progress of the past in combination with new tools and techniques, such as neuroimaging and molecular biology, has positioned neuroscience on the cusp of even greater transformational progress in our understanding of the brain and how its inner workings result in mental activity. This workshop summary highlights the important issues and challenges facing the field of neuroscience as presented to those in attendance at the workshop, as well as the subsequent discussion that resulted. As a result, three overarching Grand Challenges emerged: How does the brain work and produce mental activity? How does physical activity in the brain give rise to thought, emotion, and behavior? How does the interplay of biology and experience shape our brains and make us who we are today? How do we keep our brains healthy? How do we protect, restore, or enhance the functioning of our brains as we age?

Available in PDF, EPUB and Kindle. Book excerpt: Most of us have no idea what’s really going on inside our heads. Yet brain scientists have uncovered details every business leader, parent, and teacher should know—like the need for physical activity to get your brain working its best. How do we learn? What exactly do sleep and stress do to our brains? Why is multi-tasking a myth? Why is it so easy to forget—and so important to repeat new knowledge? Is it true that men and women have different brains? In Brain Rules, Dr. John Medina, a molecular biologist, shares his lifelong interest in how the brain sciences might influence the way we teach our children and the way we work. In each chapter, he describes a brain rule—what scientists know for sure about how our brains work—and then offers transformative ideas for our daily lives. Medina’s fascinating stories and infectious sense of humor breathe life into brain science. You’ll learn why Michael Jordan was no good at baseball. You’ll peer over a surgeon’s shoulder as he proves that most of us have a Jennifer Aniston neuron. You’ll meet a boy who has an amazing memory for music but can’t tie his own shoes. You will discover how: Every brain is wired differently Exercise improves cognition We are designed to never stop learning and exploring Memories are volatile Sleep is powerfully linked with the ability to learn Vision trumps all of the other senses Stress changes the way we learn In the end, you’ll understand how your brain really works—and how to get the most out of it.
