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."




Clinical Neuroembryology


Book Description

Progress in developmental neurobiology and advances in (neuro) genetics have been spectacular. The high resolution of modern imaging techniques applicable to developmental disorders of the human brain and spinal cord have created a novel insight into the developmental history of the central nervous system (CNS). This book provides a comprehensive overview of the development of the human CNS in the context of its many developmental disorders. It provides a unique combination of data from human embryology, animal research and developmental neuropathology, and there are more than 400 figures in over a hundred separate illustrations.




The Embryology of the Human Locomotor System


Book Description

In this Atlas I want to share with my fellow clinicians the fascina tion I experienced while discovering the marvels of embryonic development. Why haven't these marvels excited me before? I believe that the use of schemata and drawings or photographs of animal embryos, commonly used in textbooks of embryology, simply did not appeal to me as a clinician. Only actual photo graphs of human embryos can establish the bond necessary for interaction. Just imagine the excitement when you find out how many struc tures you can recognize in a 5-week-old embryo, barely measuring 1 cm in length. But our fascination does not stop here. The pro gression of changes taking place during the next 3 weeks is so rapid that at the time when the embryo measures 3 cm, all structures familiar to us are not only easily recognizable, but also already in their anatomical position. How can we hide our amazement when we realize that such a state of perfection is present in an embryo a bit longer than the distal phalanx of our little finger? At 8 weeks the embryonic period ends and the fetal one starts. Although the shape and the relative size of bones, joints, muscles, nerves, and vessels will undergo changes, the basic elements are all in place. This implies that major malformations must develop during the embryonic period.




From Neurons to Neighborhoods


Book Description

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.




The Spinal Cord


Book Description




The Circuitry of the Human Spinal Cord


Book Description

Studies of human movement have proliferated in recent years, and there have been many studies of spinal pathways in humans, their role in movement, and their dysfunction in neurological disorders. This comprehensive reference surveys the literature related to the control of spinal cord circuits in human subjects, showing how they can be studied, their role in normal movement, and how they malfunction in disease states. Chapters are highly illustrated and consistently organised, reviewing, for each pathway, the experimental background, methodology, organisation and control, role during motor tasks, and changes in patients with CNS lesions. Each chapter concludes with a helpful resume that can be used independently of the main text to provide practical guidance for clinical studies. This will be essential reading for research workers and clinicians involved in the study, treatment and rehabilitation of movement disorders.




Atlas of Human Central Nervous System Development -5 Volume Set


Book Description

The publication of the fifth volume completes this historic series of atlases. Available for the first time as a set, this award winning series provides the only complete record of the development of the human central nervous system from spinal cord gestation through the third trimester. The contents of the atlases are organized by coronal, sagittal, and horizontal planes of sectioning to ensure that nearly every structure in the developing brain is represented pictorially. Each volume provides two page spreads containing high resolution black and white images on one side and ghost images on the other with unabbreviated labels to apprise readers of the exact structures identified. The final volume provides a concluding essay that summarizes major events of CNS development, while offering a theoretical account of the morphogenetic processes involved. For more details, readers can access information specific to each volume: Vol. 1: Cat. No. 1420 The Spinal Cord from Gestational Week 4 to the 4th Postnatal Month Vol. 2: Cat. No. 1421 The Human Brain During the Second Trimester Vol. 3: Cat. No. 1422 The Human Brain During the Third Trimester Vol. 4: Cat. No. 1423 The Human Brain During the Late First Trimester Vol. 5: Cat. No. 1424 The Human Brain During the Early First Trimester From the 1960s through the 1980s, the work of legendary pioneers, Shirley Bayer and Joseph Altman chronicled the development of the rat nervous system. In the 1990s, they shifted their attention to humans when they realized how little was known about the development of the human central nervous system. Many disorders resulting from abnormal neural deficits could be better understood if normal development was itself better known. Bayer and Altman decided to apply their knowledge of rat nervous system development to humans by directly examining histological sections of normal human specimens. Funding their own work, they took over 10,000 photographs of the best preserved specimens available. Each of the photos was then scanned to create digitalized files that could be further examined with sophisticated equipment, including 3- dimensional reconstruction software. This set of atlases is the result of this effort. "We embarked on this ambitious project for two reasons. First, to fill a gaping void in the literature. ...Second, we hoped that by extrapolating from the experimental data obtained in animals, we could go beyond a mere narrative account of developmental landmarks in human CNS development to a dynamic analysis of some of the morphogenetic processes involved. What we were surprised to find is that our detailed examination of the full course of CNS development in normal human embryos and fetuses has come to shed new light on some of the basic mechanisms involved in the production, migration, differentiation, and assembly of CNS neurons...." This information is included in an extended monograph in Volume 5 that will no doubt serve as a launching pad for future research. Altman and Bayer, working for three decades at Purdue and Indiana Universities, revolutionized the research methods and pioneered the results that are available today.
