Connecting in vitro and in vivo studies of the mammalian brain.
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.
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.

A pioneering neuroscientist shows how the long-sought merger of brains with machines is about to become a paradigm-shifting reality Imagine living in a world where people use their computers, drive their cars, and communicate with one another simply by thinking. In this stunning and inspiring work, Duke University neuroscientist Miguel Nicolelis shares his revolutionary insights into how the brain creates thought and the human sense of self—and how this might be augmented by machines, so that the entire universe will be within our reach. Beyond Boundaries draws on Nicolelis's ground-breaking research with monkeys that he taught to control the movements of a robot located halfway around the globe by using brain signals alone. Nicolelis's work with primates has uncovered a new method for capturing brain function—by recording rich neuronal symphonies rather than the activity of single neurons. His lab is now paving the way for a new treatment for Parkinson's, silk-thin exoskeletons to grant mobility to the paralyzed, and breathtaking leaps in space exploration, global communication, manufacturing, and more. Beyond Boundaries promises to reshape our concept of the technological future, to a world filled with promise and hope.
This e-book will review special features of the cerebral circulation and how they contribute to the physiology of the brain. It describes structural and functional properties of the cerebral circulation that are unique to the brain, an organ with high metabolic demands and the need for tight water and ion homeostasis. Autoregulation is pronounced in the brain, with myogenic, metabolic and neurogenic mechanisms contributing to maintain relatively constant blood flow during both increases and decreases in pressure. In addition, unlike peripheral organs where the majority of vascular resistance resides in small arteries and arterioles, large extracranial and intracranial arteries contribute significantly to vascular resistance in the brain. The prominent role of large arteries in cerebrovascular resistance helps maintain blood flow and protect downstream vessels during changes in perfusion pressure. The cerebral endothelium is also unique in that its barrier properties are in some way more like epithelium than endothelium in the periphery. The cerebral endothelium, known as the blood-brain barrier, has specialized tight junctions that do not allow ions to pass freely and has very low hydraulic conductivity and transcellular transport. This special configuration modifies Starling's forces in the brain microcirculation such that ions retained in the vascular lumen oppose water movement due to hydrostatic pressure. Tight water regulation is necessary in the brain because it has limited capacity for expansion within the skull. Increased intracranial pressure due to vasogenic edema can cause severe neurologic complications and death.
In this “riveting read, meshing memoir with scientific explication” (Nature), a world-renowned neuroscientist reveals how he learned to communicate with patients in vegetative or “gray zone” states and, more importantly, he explains what those interactions tell us about the working of our own brains. “Vivid, emotional, and thought-provoking” (Publishers Weekly), Into the Gray Zone takes readers to the edge of a dazzling, humbling frontier in our understanding of the brain: the so-called “gray zone” between full consciousness and brain death. People in this middle place have sustained traumatic brain injuries or are the victims of stroke or degenerative diseases, such as Alzheimer’s and Parkinson’s. Many are oblivious to the outside world, and their doctors believe they are incapable of thought. But a sizeable number—as many as twenty percent—are experiencing something different: intact minds adrift deep within damaged brains and bodies. An expert in the field, Adrian Owen led a team that, in 2006, discovered this lost population and made medical history. Scientists, physicians, and philosophers have only just begun to grapple with the implications. Following Owen’s journey of exciting medical discovery, Into the Gray Zone asks some tough and terrifying questions, such as: What is life like for these patients? What can their families and friends do to help them? What are the ethical implications for religious organizations, politicians, the Right to Die movement, and even insurers? And perhaps most intriguing of all: in defining what a life worth living is, are we too concerned with the physical and not giving enough emphasis to the power of thought? What, truly, defines a satisfying life? “Strangely uplifting…the testimonies of people who have returned from the gray zone evoke the mysteries of consciousness and identity with tremendous power” (The New Yorker). This book is about the difference between a brain and a mind, a body and a person. Into the Gray Zone is “a fascinating memoir…reads like a thriller” (Mail on Sunday).
Conventional wisdom assumes that sleep is a resting state of the brain, with negligible activity of cortical neurons. Here, the author brings new evidence favoring the idea that during sleep, memory traces acquired while awake are consolidated. Mircea Steriade focuses on the coalescence of different sleep rhythms in interacting corticothalamic networks and on three types of paroxysmal disorders: spike-wave seizures as in absence epilepsy, Lennox-Gastaut seizures, and temporal-lobe epilepsy. Many physiological correlates of waking and sleep states as well as diverse types of epileptic seizures are also discussed.
