Genes, Cells, and Brains


Book Description

Our fates lie in our genes and not in the stars, said James Watson, co-discoverer of the structure of DNA. But Watson could not have predicted the scale of the industry now dedicated to this new frontier. Since the launch of the multibillion-dollar Human Genome Project, the biosciences have promised miraculous cures and radical new ways of understanding who we are. But where is the new world we were promised? Now updated with a new afterword, Genes, Cells and Brains asks why the promised cornucopia of health benefits has failed to emerge and reveals the questionable enterprise that has grown out of bioethics. The authors, feminist sociologist Hilary Rose and neuroscientist Steven Rose, examine the establishment of biobanks, the rivalries between public and private gene sequencers, and the rise of stem cell research. The human body is becoming a commodity, and the unfulfilled promises of the science behind this revolution suggest profound failings in genomics itself.




Genes, Brains, and Human Potential


Book Description

For countless generations people have been told that their potential as humans is limited and fundamentally unequal. The social order, they have been assured, is arranged by powers beyond their control. More recently the appeal has been to biology, specifically the genes, brain sciences, the concept of intelligence, and powerful new technologies. Reinforced through the authority of science and a growing belief in bio-determinism, the ordering of the many for the benefit of a few has become more entrenched. Yet scientists are now waking up to the influence of ideology on research and its interpretation. In Genes, Brains, and Human Potential, Ken Richardson illustrates how the ideology of human intelligence has infiltrated genetics, brain sciences, and psychology, flourishing in the vagueness of basic concepts, a shallow nature-versus-nurture debate, and the overhyped claims of reductionists. He shows how ideology, more than pure science, has come to dominate our institutions, especially education, encouraging fatalism about the development of human intelligence among individuals and societies. Genes, Brains, and Human Potential goes much further: building on work being done in molecular biology, epigenetics, dynamical systems, evolution theory, and complexity theory, it maps a fresh understanding of intelligence and the development of human potential. Concluding with an upbeat message for human possibilities, this synthesis of diverse perspectives will engender new conversations among students, researchers, and other interested readers.







Innate


Book Description

"What makes you the way you are--and what makes each of us different from everyone else? In Innate, leading neuroscientist and popular science blogger Kevin Mitchell traces human diversity and individual differences to their deepest level: in the wiring of our brains. Deftly guiding us through important new research, including his own groundbreaking work, he explains how variations in the way our brains develop before birth strongly influence our psychology and behavior throughout our lives, shaping our personality, intelligence, sexuality, and even the way we perceive the world. We all share a genetic program for making a human brain, and the program for making a brain like yours is specifically encoded in your DNA. But, as Mitchell explains, the way that program plays out is affected by random processes of development that manifest uniquely in each person, even identical twins. The key insight of Innate is that the combination of these developmental and genetic variations creates innate differences in how our brains are wired--differences that impact all aspects of our psychology--and this insight promises to transform the way we see the interplay of nature and nurture. Innate also explores the genetic and neural underpinnings of disorders such as autism, schizophrenia, and epilepsy, and how our understanding of these conditions is being revolutionized. In addition, the book examines the social and ethical implications of these ideas and of new technologies that may soon offer the means to predict or manipulate human traits. Compelling and original, Innate will change the way you think about why and how we are who we are."--Provided by the publisher.




Discovering the Brain


Book Description

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."




The Secret Language of Cells


Book Description

Your cells are talking about you. Right now, both your inner and outer worlds are abuzz with chatter among living cells of every possible kind—from those in your body and brain to those in the environment around you. From electrical alerts to chemical codes, the greatest secret of modern biology, hiding in plain sight, is that all of life's activity boils down to one thing: conversation. While cells are commonly considered the building block of living things, it is actually the communication between cells that brings us to life, controlling our bodies and brains, determining whether we are healthy or sick, and directly influencing how we think, feel, and behave. In The Secret Language of Cells, doctor and neuroscientist Jon Lieff lets us listen in on these conversations, and reveals their significance for everything from mental health to cancer. He explains the surprising science of how very different cells—bacteria and brain cells, blood cells and viruses—all speak the same language. This overarching principle has been long overlooked because scientific journals use impenetrable jargon that makes it hard to be understood across disciplines, much less by the general public. Lieff presents a fascinating and accessible look into cellular communication science—a groundbreaking and comprehensive exploration of this biological phenomenon. In these pages, discover the intriguing lives of cells as they ask questions, get answers, give feedback, gather information, call for each other, and make complex decisions. During infections, immune T-cells tell brain cells that we should "feel sick" and lie down. Cancer cells warn their community about immune and microbe attacks. Gut cells talk with microbes to determine which are friends and which are enemies, and microbes talk with each other and with much more complicated human cells in ways that determine which medicines work and which will fail. With applications for immunity, chronic pain, weight loss, depression, cancer treatment, and virtually every aspect of health and biology, cellular communication is revolutionizing our understanding not just of disease, but of life itself. The Secret Language of Cells is required reading for anyone interested in following the conversation.




From Molecules to Minds


Book Description

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?




From Neurons to Neighborhoods


Book Description

How we raise young children is one of today's most highly personalized and sharply politicized issues, in part because each of us can claim some level of "expertise." The debate has intensified as discoveries about our development-in the womb and in the first months and years-have reached the popular media. How can we use our burgeoning knowledge to assure the well-being of all young children, for their own sake as well as for the sake of our nation? Drawing from new findings, this book presents important conclusions about nature-versus-nurture, the impact of being born into a working family, the effect of politics on programs for children, the costs and benefits of intervention, and other issues. The committee issues a series of challenges to decision makers regarding the quality of child care, issues of racial and ethnic diversity, the integration of children's cognitive and emotional development, and more. Authoritative yet accessible, From Neurons to Neighborhoods presents the evidence about "brain wiring" and how kids learn to speak, think, and regulate their behavior. It examines the effect of the climate-family, child care, community-within which the child grows.




The Birth of the Mind


Book Description

In The Birth of the Mind, award-winning cognitive scientist Gary Marcus irrevocably alters the nature vs. nurture debate by linking the findings of the Human Genome Project to the development of the brain. Scientists have long struggled to understand how a tiny number of genes could contain the instructions for building the human brain, arguably the most complex device in the known universe. Synthesizing up-to-the-minute research with his own original findings on child development, Marcus is the first to resolve this apparent contradiction. Vibrantly written and completely accessible to the lay reader, The Birth of the Mind will forever change the way we think about our origins and ourselves.




Connectome


Book Description

“Accessible, witty . . . an important new researcher, philosopher and popularizer of brain science . . . on par with cosmology’s Brian Greene and the late Carl Sagan” (The Plain Dealer). One of the Wall Street Journal’s 10 Best Nonfiction Books of the Year and a Publishers Weekly “Top Ten in Science” Title Every person is unique, but science has struggled to pinpoint where, precisely, that uniqueness resides. Our genome may determine our eye color and even aspects of our character. But our friendships, failures, and passions also shape who we are. The question is: How? Sebastian Seung is at the forefront of a revolution in neuroscience. He believes that our identity lies not in our genes, but in the connections between our brain cells—our particular wiring. Seung and a dedicated group of researchers are leading the effort to map these connections, neuron by neuron, synapse by synapse. It’s a monumental effort, but if they succeed, they will uncover the basis of personality, identity, intelligence, memory, and perhaps disorders such as autism and schizophrenia. Connectome is a mind-bending adventure story offering a daring scientific and technological vision for understanding what makes us who we are, as individuals and as a species. “This is complicated stuff, and it is a testament to Dr. Seung’s remarkable clarity of exposition that the reader is swept along with his enthusiasm, as he moves from the basics of neuroscience out to the farthest regions of the hypothetical, sketching out a spectacularly illustrated giant map of the universe of man.” —TheNew York Times “An elegant primer on what’s known about how the brain is organized and how it grows, wires its neurons, perceives its environment, modifies or repairs itself, and stores information. Seung is a clear, lively writer who chooses vivid examples.” —TheWashington Post
