Book Description
Connecting in vitro and in vivo studies of the mammalian brain. In this book Mircea Steriade cautions against the tendency of some neuroscientists to infer global brain functions such as arousal and sleep, epileptic events, and even conscious thinking from the properties of single cells. Based on his lifetime of research on intact brains, Steriade emphasizes the need to understand isolated networks within the context of the whole mammalian brain and to understand the brain of a behaving animal in terms of its fully dissected circuits. As much as knowledge of brain anatomy and function has progressed, Steriade is highly skeptical about the quest to relate consciousness to specific neuronal types. The book's sections are Changing Concepts of Localization of Brain Function, Evolution of Methods in Brain Studies, Similar and Contrasting Results from Studies in the Intact and Sliced Brain, Building Blocks of Synaptic Networks Underlying Normal and Paroxysmal States, and Of Neurons and Consciousness.

Book Description
In little less than a decade brain slices have gained prominence among neurobiologists as appropriate tools to study cellular electrophysiolog ical aspects of mammalian brain function. The purpose of this volume is to present in some detail several inquiries in the brain sciences that have benefited greatly by the use of brain slices. The book is directed primarily toward advanced students and researchers wishing to evaluate the impact these in vitro preparations of the mammalian brain are having on neurobiology. The term brain slice has come to refer to thin (100-700 j. Lm) sections of a brain region prepared from adult mammals and maintained for many hours in vitro, for either electrophysiological or biochemical stud ies. In addition to good accessibility, slices feature relatively intact syn aptic connections that allow a variety of experiments not feasible with standard in vivo or tissue culture preparations. Certain electrophysiol ogical studies once practical only with invertebrate models are becoming routine with mammalian brain slices. The ability to perform both bio chemical and electro physiological experiments on the same piece of CNS tissue provides additional bright prospects for future research. Although most of the electrophysiological studies have dealt with hippocampal slices, it should be evident from this book that slice methodology is not limited to the hippocampus. The Appendix, "Brain Slice Methods," is a multiauthored treatment of the technical aspects of brain slice work, collected into one document.

Book Description
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.

Book Description
Neuroscientist V.S. Ramachandran is internationally renowned for uncovering answers to the deep and quirky questions of human nature that few scientists have dared to address. His bold insights about the brain are matched only by the stunning simplicity of his experiments -- using such low-tech tools as cotton swabs, glasses of water and dime-store mirrors. In Phantoms in the Brain, Dr. Ramachandran recounts how his work with patients who have bizarre neurological disorders has shed new light on the deep architecture of the brain, and what these findings tell us about who we are, how we construct our body image, why we laugh or become depressed, why we may believe in God, how we make decisions, deceive ourselves and dream, perhaps even why we're so clever at philosophy, music and art. Some of his most notable cases: A woman paralyzed on the left side of her body who believes she is lifting a tray of drinks with both hands offers a unique opportunity to test Freud's theory of denial. A man who insists he is talking with God challenges us to ask: Could we be "wired" for religious experience? A woman who hallucinates cartoon characters illustrates how, in a sense, we are all hallucinating, all the time. Dr. Ramachandran's inspired medical detective work pushes the boundaries of medicine's last great frontier -- the human mind -- yielding new and provocative insights into the "big questions" about consciousness and the self.

Book Description
Why our human brains are awesome, and how we left our cousins, the great apes, behind: a tale of neurons and calories, and cooking. Humans are awesome. Our brains are gigantic, seven times larger than they should be for the size of our bodies. The human brain uses 25% of all the energy the body requires each day. And it became enormous in a very short amount of time in evolution, allowing us to leave our cousins, the great apes, behind. So the human brain is special, right? Wrong, according to Suzana Herculano-Houzel. Humans have developed cognitive abilities that outstrip those of all other animals, but not because we are evolutionary outliers. The human brain was not singled out to become amazing in its own exclusive way, and it never stopped being a primate brain. If we are not an exception to the rules of evolution, then what is the source of the human advantage? Herculano-Houzel shows that it is not the size of our brain that matters but the fact that we have more neurons in the cerebral cortex than any other animal, thanks to our ancestors' invention, some 1.5 million years ago, of a more efficient way to obtain calories: cooking. Because we are primates, ingesting more calories in less time made possible the rapid acquisition of a huge number of neurons in the still fairly small cerebral cortex—the part of the brain responsible for finding patterns, reasoning, developing technology, and passing it on through culture. Herculano-Houzel shows us how she came to these conclusions—making “brain soup” to determine the number of neurons in the brain, for example, and bringing animal brains in a suitcase through customs. The Human Advantage is an engaging and original look at how we became remarkable without ever being special.
