Book Description
Primary cortical areas receive a defmed input which makes them especially appropria te for investigating cortical functions. The striate area is the only isocortical field which can be delineated unequivocally in the human brain. Nevertheless, there have been only a few morphological studies of this particular area (cytoarchitectonic studies: Bailey and Von Bonin 1951, Beck 1934, Von Economo and Koskinas 1925, Filimo noff 1932; myeloarchitectonic studies: Sanides and Vitzthum 1965, Vogt and Vogt 1919; pigmentoarchitectonic studies: Braak H 1976, 1977). For Golgi impregnations, Ramon y Cajal (1900, 1909-1911), Conel (1939-1967), and Shkol'nik-Yarros (1971) preferred the incompletely myelinated material taken from brains of young childre- a fact that somewhat restricts their descriptions of the human striate area. Pigment preparations (Braak H 1978) provide a detailed view of the lamination of cortical areas. Furthermore, many types of cortical nerve cells reveal a typicallipofus cin-pigment pattern (Braak H 1974a). Thus, a correlation can be drawn between the type of neuron as classified in Golgi preparations and the characteristic number and distribution of lipofuscin granules found in the cell body. Neurolipofuscin granules can therefore be considered the internal markers. In this study several cell types of the striate area have been identified under light and electron microscopes by means of their characteristic pigmentation.

Book Description
Neurology of Vision and Visual Disorders, Volume 178 in the Handbooks of Neurology series provides comprehensive summaries of recent research on the brain and nervous system. This volume reviews alterations in vision that stem from the retina to the cortex. Coverage includes content on vision and driving derived from the large amount of time devoted in clinics to determining who is safe to drive, along with research on the interplay between visual loss, attention and strategic compensations that may determine driving suitability. The title concludes with vision therapies and the evidence behind these approaches. Each chapter is co-written by a basic scientist collaborating with a clinician to provide a solid underpinning of the mechanisms behind the clinical syndromes. - Reviews the neurological underpinnings of visual perception disorders - Encompasses the cortex to the retina - Covers functional organization, electrophysiology and subcortical visual pathways - Discusses assessment, diagnosis and management of visual perception disorders - Includes international experts from Australia, Canada, Denmark, Germany, Singapore, and the UK and US

Book Description
Evolution of Nervous Systems, Second Edition, Four Volume Set is a unique, major reference which offers the gold standard for those interested both in evolution and nervous systems. All biology only makes sense when seen in the light of evolution, and this is especially true for the nervous system. All animals have nervous systems that mediate their behaviors, many of them species specific, yet these nervous systems all evolved from the simple nervous system of a common ancestor. To understand these nervous systems, we need to know how they vary and how this variation emerged in evolution. In the first edition of this important reference work, over 100 distinguished neuroscientists assembled the current state-of-the-art knowledge on how nervous systems have evolved throughout the animal kingdom. This second edition remains rich in detail and broad in scope, outlining the changes in brain and nervous system organization that occurred from the first invertebrates and vertebrates, to present day fishes, reptiles, birds, mammals, and especially primates, including humans. The book also includes wholly new content, fully updating the chapters in the previous edition and offering brand new content on current developments in the field. Each of the volumes has been carefully restructured to offer expanded coverage of non-mammalian taxa, mammals, primates, and the human nervous system. The basic principles of brain evolution are discussed, as are mechanisms of change. The reader can select from chapters on highly specific topics or those that provide an overview of current thinking and approaches, making this an indispensable work for students and researchers alike. Presents a broad range of topics, ranging from genetic control of development in invertebrates, to human cognition, offering a one-stop resource for the evolution of nervous systems throughout the animal kingdom Incorporates the expertise of over 100 outstanding investigators who provide their conclusions in the context of the latest experimental results Presents areas of disagreement and consensus views that provide a holistic view of the subjects under discussion

Book Description
A Physiological Approach to Clinical Neurology deals with the mechanism of various neurological symptoms and signs in terms of disordered physiology. Topics covered by this book include pain and other sensations; weakness; the tendon jerk and the stretch reflex; and disordered control of motor neurons. The disorders of basal ganglia and cerebellum are also considered, along with consciousness and unconsciousness; the mechanism of epilepsy; and the relationship between brain and mind. This book is comprised of 11 chapters and begins by introducing the reader to the clinical analysis of sensory and motor disorders. The discussion then turns to the perception of pain and other kinds of sensation; the clinical approach to the problem of weakness; and the clinical significance of the tendon jerk. In the chapters that follow, appraisal of a neurophysiological thought is applied to common neurological disorders such as Parkinson's disease, hemiballismus, epilepsy, and developmental anomalies like platybasia. The last chapter explores the phenomena of mind and its connection to the brain as well as its influence on the body, paying particular attention to perception, memory, and emotion. This monograph is intended for those who are proceeding into the clinical years of a medical course, to those who are studying for senior qualifications in internal medicine or neurology, and to those who are merely curious about the cause of neurological phenomena that they observe daily in their patients.

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."
