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 Cerebral Circulation


Book Description

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.




Galen on the Brain


Book Description

This book is a study of the ways in which Galen sought to establish the brain as the regent part (hegemonikon) of the body, utilising a rigorous anatomical epistemology and an often sophisticated (but perforce limited) set of physiological arguments Part One surveys the medical and philosophical past in which the study of the brain occured, and looks at the materials and methods which Galen employs to legitimate his hegemonic argumentation. Part Two examines Galen's anatomical understanding of the brain, especially the ventricles. Part Three offers a critical evaluation of Galen's physiolgy of the brain. This is the first monograph to offer a detailed account of this subject, setting it within the cultural and intellectual contexts of its era, and will be of interest to those in classics, medical history, history andphilosophy of science and the history of ideas.




The Brain and Behavior


Book Description

New edition building on the success of previous one. Retains core aim of providing an accessible introduction to behavioral neuroanatomy.




The Brain Book


Book Description

This science ebook of award-wiining print edition uses the latest findings from neuroscience research and brain-imaging technology to take you on a journey into the human brain. CGI artworks and brain MRI scans reveal the brain's anatomy in unprecedented detail. Step-by-step sequences unravel and simplify the complex processes of brain function, such as how nerves transmit signals, how memories are laid down and recalled, and how we register emotions. The book answers fundamental and compelling questions about the brain: what does it means to be conscious, what happens when we're asleep,and are the brains of men and women different? Written by award-winning author Rita Carter, this is an accessible and authoritative reference book to a fascinating part of the human body. Thanks to improvements in scanning technology, our understanding of the brain is changing fast. Now in its third edition, the Brain Book provides an up-to-date guide to one of science's most exciting frontiers. With its coverage of over 50 brain-related diseases and disorders - from strokes to brain tumours and schizophrenia - it is also an essential manual for students and healthcare professionals.




The Parietal Lobe


Book Description

The Parietal Lobe, Volume 151, the latest release from the Handbook of Clinical Neurology series, provides a foundation on the neuroanatomy, neurophysiology and clinical neurology/neuropsychology of the parietal lobe that is not only applicable to both basic researchers and clinicians, but also to students and specialists who are interested in learning more about disorders brought on by damage or dysfunction. Topics encompass the evolution, anatomy, connections, and neurophysiology, the major neurological and neuropsychological deficits and syndromes caused by damage, the potential for improvement via transcranial stimulation, and the role of the parietal in the cerebral networks for perception and action. - Provides a broad overview of the neuroanatomy, neurophysiology and clinical neurology of this region of the cortex - Offers additional insights regarding the role of the parietal in the cerebral networks for perception and action - Addresses the most frequent complications associated with damage, including somatosensory, perceptual, language, and memory, deficits, pain, optic ataxia, spatial neglect, apraxia, and more - Edited work with chapters authored by global leaders in the field - Presents the broadest, most expert coverage available




Essential Clinical Anatomy of the Nervous System


Book Description

Essential Clinical Anatomy of the Nervous System is designed to combine the salient points of anatomy with typical pathologies affecting each of the major pathways that are directly applicable in the clinical environment. In addition, this book highlights the relevant clinical examinations to perform when examining a patient's neurological system, to demonstrate pathology of a certain pathway or tract. Essential Clinical Anatomy of the Nervous System enables the reader to easily access the key features of the anatomy of the brain and main pathways which are relevant at the bedside or clinic. It also highlights the typical pathologies and reasoning behind clinical findings to enable the reader to aid deduction of not only what is wrong with the patient, but where in the nervous system that the pathology is. - Anatomy of the brain and neurological pathways dealt with as key facts and summary tables essential to clinical practice. - Succinct yet comprehensive format with quick and easy access facts in clearly laid out key regions, common throughout the different neurological pathways. - Includes key features and hints and tips on clinical examination and related pathologies, featuring diagnostic summaries of potential clinical presentations.
