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."

An essential reconsideration of one of the most far-reaching theories in modern neuroscience and psychology. In 1992, a group of neuroscientists from Parma, Italy, reported a new class of brain cells discovered in the motor cortex of the macaque monkey. These cells, later dubbed mirror neurons, responded equally well during the monkey’s own motor actions, such as grabbing an object, and while the monkey watched someone else perform similar motor actions. Researchers speculated that the neurons allowed the monkey to understand others by simulating their actions in its own brain. Mirror neurons soon jumped species and took human neuroscience and psychology by storm. In the late 1990s theorists showed how the cells provided an elegantly simple new way to explain the evolution of language, the development of human empathy, and the neural foundation of autism. In the years that followed, a stream of scientific studies implicated mirror neurons in everything from schizophrenia and drug abuse to sexual orientation and contagious yawning. In The Myth of Mirror Neurons, neuroscientist Gregory Hickok reexamines the mirror neuron story and finds that it is built on a tenuous foundation—a pair of codependent assumptions about mirror neuron activity and human understanding. Drawing on a broad range of observations from work on animal behavior, modern neuroimaging, neurological disorders, and more, Hickok argues that the foundational assumptions fall flat in light of the facts. He then explores alternative explanations of mirror neuron function while illuminating crucial questions about human cognition and brain function: Why do humans imitate so prodigiously? How different are the left and right hemispheres of the brain? Why do we have two visual systems? Do we need to be able to talk to understand speech? What’s going wrong in autism? Can humans read minds? The Myth of Mirror Neurons not only delivers an instructive tale about the course of scientific progress—from discovery to theory to revision—but also provides deep insights into the organization and function of the human brain and the nature of communication and cognition.

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.

If humans are purely physical, and if it is the brain that does the work formerly assigned to the mind or soul, then how can it fail to be the case that all of our thoughts and actions are determined by the laws of neurobiology? If this is the case, then free will, moral responsibility, and, indeed, reason itself would appear to be in jeopardy. Nancey Murphy and Warren S. Brown here defend a non-reductive version of physicalism whereby humans are (sometimes) the authors of their own thoughts and actions. Did My Neurons Make Me Do It? brings together insights from both philosophy and the cognitive neurosciences to defeat neurobiological reductionism. One resource is a 'post-Cartesian' account of mind as essentially embodied and constituted by action-feedback-evaluation-action loops in the environment, and 'scaffolded' by cultural resources. Another is a non-mysterious account of downward (mental) causation explained in terms of a complex, higher-order system exercising constraints on lower-level causal processes. These resources are intrinsically related: the embeddedness of brain events in action-feedback loops is the key to their mentality, and those broader systems have causal effects on the brain itself. With these resources Murphy and Brown take on two problems in philosophy of mind: a response to the charges that physicalists cannot account for the meaningfulness of language nor the causal efficacy of the mental qua mental. Solutions to these problems are a prerequisite to addressing the central problem of the book: how can biological organisms be free and morally responsible? The authors argue that the free-will problem is badly framed if it is put in terms of neurobiological determinism; the real issue is neurobiological reductionism. If it is indeed possible to make sense of the notion of downward causation, then the relevant question is whether humans exert downward causation over some of their own parts and processes. If all organisms do this to some extent, what needs to be added to this animalian flexibility to constitute free and responsible action? The keys are sophisticated language and hierarchically ordered cognitive processes allowing (mature) humans to evaluate their own actions, motives, goals, and rational and moral principles.

At the crossroads of art and science, Beautiful Brain presents Nobel Laureate Santiago Ramón y Cajal’s contributions to neuroscience through his groundbreaking artistic brain imagery. Santiago Ramón y Cajal (1852–1934) was the father of modern neuroscience and an exceptional artist. He devoted his life to the anatomy of the brain, the body’s most complex and mysterious organ. His superhuman feats of visualization, based on fanatically precise techniques and countless hours at the microscope, resulted in some of the most remarkable illustrations in the history of science. Beautiful Brain presents a selection of his exquisite drawings of brain cells, brain regions, and neural circuits with accessible descriptive commentary. These drawings are explored from multiple perspectives: Larry W. Swanson describes Cajal’s contributions to neuroscience; Lyndel King and Eric Himmel explore his artistic roots and achievement; Eric A. Newman provides commentary on the drawings; and Janet M. Dubinsky describes contemporary neuroscience imaging techniques. This book is the companion to a traveling exhibition opening at the Weisman Art Museum in Minneapolis in February 2017, marking the first time that many of these works, which are housed at the Instituto Cajal in Madrid, have been seen outside of Spain. Beautiful Brain showcases Cajal’s contributions to neuroscience, explores his artistic roots and achievement, and looks at his work in relation to contemporary neuroscience imaging, appealing to general readers and professionals alike.

The aim of this book is to bring together social scientists, cognitive scientists, psychologists, neuroscientists, neuropsychologists and others to promote a dialogue about the variety of processes involved in social cognition, as well as the relevance of mirroring neural systems to those processes. Social cognition is a broad discipline that encompasses many issues not yet adequately addressed by neurobiologists. Yet, it is a strong belief that framing these issues in terms of the neural basis of social cognition, especially within an evolutionary perspective, can be a very fruitful strategy. This book includes some of the leading thinkers in the nascent field of mirroring processes and reflects the authors’ attempts to till common ground from a variety of perspectives. The book raises contrary views and addresses some of the most vexing yet core questions in the field – providing the basis for extended discussion among interested readers and laying down guidelines for future research. It has been argued that interaction with members of one’s own social group enhances cognitive development in primates and especially humans (Barrett & Henzi, 2005). Byrne and Whiten (1988), Donald (1991), and others have speculated that abilities such as cooperation, deception, and imitation led to increasingly complex social interactions among primates resulting in a tremendous expansion of the cerebral cortex. The evolutionary significance of an imitation capability in primates is matched by its ontological consequences.
