Ions, their transport across membranes, and their flow through specialized ion channels are central to the understanding of brain function, normal and pathological. The first part of this book deals with the regulation of ions in brain extra- and intracellular fluids. Regulation is effected by the blood-brain barrier, and by membrane ion pumps and other transport mechanisms of neurons and glial cells. Normally adjusted for optimal neural function, ion levels can change and alter the excitability of neurons and influence synaptic transmission in healthy and diseased brains. After an introduction to the electrophysiology of epilepsy, and a description of experimental seizure "models," the second part discusses the roles of the faulty regulation of ions and of the diseases of ion channels in generating epileptic seizures. The mechanisms of action of various anticonvulsant drugs are also considered. The third part is devoted to the phenomenon of spreading depression and its likely role in human diseases. The final chapters of the book deal with the role of ions in the devastation caused by lack of oxygen and by insufficient blood flow to brain tissue, and the reasons for the exceptional vulnerability of certain classes of central neurons in hypoxia and stroke. The book will be of interest to neuroscientists, neurobiologists, neurophysiologists, neurologists, neurosurgeons, and to their students and trainees.

This book contains the contributions and discussions of the second symposium on vascular smooth muscles held in Ttibingen in February, 1976. It provides an up-to-date review of the role of ions in the trans mission of signals from the perivascular space to the contractile ele ments of the smooth muscle cells. The various aspects are mainly discussed from a functional point of view and only few contributions concern the morphologic variations of cells .during varying ion activity. Special emphasis was placed on the significance of ion variations in the cerebral tissue and their rela tion to metabolic and nervous control of the brain vessels. It could be seen in this symposium that new techniques enabled the in vestigators to make considerable progress in the understanding of the actions and the interactions of ions on the membranes and on the inter nal structures of the smooth muscle cells if one compares the findings with the results of the previous symposium held in Ttibingen in 1972. It became evident that the insight into ionic actions enables the de velopment of powerful tools to be utilized in future therapy of dis turbances of local blood flow regulation. The participants of the symposium render thanks to the Dr. Thiemann GmbH in Ltinen, which supported the symposium and this publication in a generous way. Finally it is a pleasure of the Editor to thank the members of the Physiological Institute of Ttibingen for their encouragement in the ar rangement of the meeting.

Metal ions in the brain are a necessity as well as a poison. The presence of metal ions in the active sites of biological catalysts or metalloproteins and in the biological functioning of nucleic acids is very well documented and they are required for brain activity. On the other hand, metals are very effective in generating oxidative stress. This effect does not only play a role in immunology but also is the root of practically all neurodegenerative disorders by inducing disease via the death of neurons. Managing metal ions in the brain could therefore be an important strategy in the search for therapeutic agents used in the treatment of neurodegenerative diseases. This new title gives an overview to key topics in the area of metal ions in the brain. It focuses on the role of metal ions in neurological systems by describing their advantageous functions as well as their poisonous features. It is therefore of interest for scientists in biochemistry and biophysics, physiology, toxicology as well as for physicians focused on this topic.

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."

Ion channels generate bioelectricity. Recent findings have documented the biophysical properties, the structure, assembly and regulation, and function and dysfunction of nonclassical nervous system ion channels. This book reviews nonclassical ion channel research, ranging from the basic biology, structure, regulations to their functions not only in normal physiology but also neurological disorders, using a variety of cutting-edge techniques and novel animal models.
