Available in PDF, EPUB and Kindle. Book excerpt: Our knowledge of cholinergic synaptic transmission in the peripheral nervous system (PNS) has expanded enormously since the early 1930's, at which time O. Loewi discovered chemical neurotransmission through acetylcholine (ACh) and the pharmacological actions of ACh were described by H. Dale and his colleagues. Description of ACh's actions and receptors in various parts of the brain was followed by a detailed analysis of ACh's synthesis, release mechanism, removal from the synaptic cleft, modes of agonist-receptor interactions, properties of regulated conductances and of the pre-and postsynaptic modulation of cholinergic synapses. Our knowledge has been increasingly consolidat ing, leading us to the recent clarification of the structure of the periph eral nicotinic receptor-ion channel and its functional properties. It is appropriate to maintain the claim that the fundamentals of our under standing of synaptic transmission come from studies on cholinergic synapses in the PNS. Contrastingly, views held on the role of cholinergic synapses in the mammalian central nervous system (CNS) are extremely controversial, although it has been clear for some time that ACh is present in the brain. Illustrating this, no unanimous view is held on the role of nicotinic receptors in the CNS. There is one notable exception to this confusion: Studies begun by J. C. Eccles and associates in the 1960's and completed by D. R. Curtis and R. W.

This book was released on 2007-04-05 with total page 698 pages. Available in PDF, EPUB and Kindle. Book excerpt: Even if the “weapons of mass destruction” (WMD) and, among them, stocks of organoph- phorus (OP) agents (also referred to as war gases and nerve gases) were not found in Iraq following the US-Iraq war, the relative ease with which these substances can be made from harmless precursors and the low cost of their manufacture will continue to fascinate pow- hungry, ruthless dictators, as well as multinational and international terrorists, particularly as the close relationship between the OP agents and useful insecticides makes it easy to disguise the importation and purchase of small amounts of the precursors. Indeed, the use by Saddam Hussein of a nerve gas against the Kurds and his possible employment of the OP agents during his war with Iran, and the Sarin attack in the Tokyo underground by an extremist religious set magnetized the world with respect to the OP drugs. As these drugs exert their toxicity via their cholinergic action on the nervous, particularly central nervous, system, it is no wonder that the research in the cholinergic ? eld attracts, and merits, our intense attention. These considerations underlie the signi? cance of this book, as Alex Karczmar devotes an entire chapter of Exploring the Vertebrate Central Cholinergic Nervous System to anticholinest- ases (antiChEs), and as he is an acknowledged expert in the ? eld of cholinergic toxicity as well as a consultant to the Surgeon General of the U. S. Army.

This book was released on 2012-12-06 with total page 610 pages. Available in PDF, EPUB and Kindle. Book excerpt: Herbert Henri Jasper is a scientist whose research activities have initiated and encompassed many of the major themes of neuroscience. He has pioneered in single unit recording, chronic neuronal studies, neurochemistry, electroencephalography, and many other disciplines. His students now hold important positions in universities and hospitals around the world. From July 21 to 23, 1986, a symposium entitled Neurotransmitters and Cortical Function: From Molecules to Mind was held in Montreal to honor Professor Jasper and to continue his pioneering efforts. The following chapters originated in that meeting. They summarize the current v vi PREFACE status of our knowledge in some of the fields influenced by Professor Jasper. They share a focus on neurotransmitters in cortical function, where we presume higher mental events originate. Professor Jasper has made contributions to the understanding of three different classes of neuro transmitters: GABA, acetylcholine, and catecholamines. It is an interest in trying to link neu rochemical events to some aspects of complex brain function and behavior that has characterized his work, and it is this philosophy that led to the present symposium to honor him. We dedicate this volume to Professor Jasper and the integrative approach that he has fostered. The Editors Montreal Contents 1. H. H.

Available in PDF, EPUB and Kindle. Book excerpt: This volume contains the scientific papers and abstracts of posters presented at the International Symposium on Molecular Insect Science held in Tucson, Arizona, October 22-27, 1989. This meeting was organized by the Center for Insect Science at the University of Arizona in response to the growing need for a forum dedicated to the impact of modern biology on insect science. While scientific studies of a few insects, notably Drosophila melanogaster, have always had a central role in the development of biology, it is only recently that tools have become available to extend these studies to other insects, including those having economic and medical importance. The Tucson meeting was evidence of how far we have come in extending modern biological tools to the study of insects. It is also evident from the contents of this book that the study of insects is making an increasingly important contribution to the advancement of biology generally. Given the large impact of insects on human life, such a development has considerable importance for human welfare, and of the welfare of the ecosystem as a whole. It should be noted that several of the participants who presented posters were invited to prepare full length papers to ensure that the book covered the major areas of insect science. The financial support of the National Science Foundation and the Monsanto Corporation is gratefully acknowledged. Thanks are also due to Sharon Richards for her dedicated work on the manuscripts.

Download or read book Mechanisms of Synaptic Transmission written by Joseph D. Robinson and published by Oxford University Press. This book was released on 2001-05-17 with total page 469 pages. Available in PDF, EPUB and Kindle. Book excerpt: Synaptic transmission plays a central role in the nervous system as the mechanism that allows for chemical and electrical communication between cells and thus connects discrete elements into the functioning whole. This is a broad account of anatomical, biochemical, embryological, medical, pathological, pharmacological, and physiological studies on synaptic transmission during the hundred years beginning in 1890. During this century, the process of synaptic transmission came to be recognized not only as the most fundamental neurophysiological process, but also as a seat of pathological changes, and as the predominant site of action for drugs used to treat a wide range of psychiatric and neurological disorders. At the same time, research from these various disciplines was transformed into a new and unifying field, neuroscience. The course of these investigations reveals ingenious experiments, powerful new techniques, and imaginative insights. The author describes broadly who did what, when, where, and how (and, in cases where it is apparent, why) and uses experimental results and interpretations to display the evolutionary course to our current understanding of how nerve cells communicate: the basic principle of neural functioning. The book will be of interest to basic and clinical neuroscientists, pharmacologists, and physiologists, to historians and philosophers of the life sciences and medicine, and to their respective students.
Download or read book The Cholinergic Synapse written by Victor P. Whittaker and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 766 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the most impressive works of scholarship in the field of experimental pharmacology has been the Heffter-Heubner Handbuch der experimentellen Pharmakologie, internationalized some years ago under the title Handbook 0/ Experimental Pharmacology and kept up to date by a series of numbered Ergiin zungswerke or supplementary volumes which have now replaced in importance the original Handbuch. These volumes constitute a valuable and continuously up dated multi author review series of topics important in modern pharmacology and allied sciences. The Editorial Board of the Handbook invited me 2 years ago to undertake, as subeditor, the preparation of a new volume entitled The Cholinergic Synapse. A previous volume in this series, vol. 15, Cholinesterases and Anticholinesterase Agents, edited by GEORGE KOELLE, was published in 1963 and was far wider in scope than its title suggested: it was, in fact an authoritative summing up of the whole subject of cholinergic function and still has some value today as an account of the state of the art as it was at that time. Since then another excellent review, of a specific cholinergic synapse, has appeared in this series: this was vol. 42, Neuromuscular Junction, edited by ELEANOR ZAIMIS and published in 1976. A third volume, vol. 53, Pharmacology o/Ganglionic Transmission, which appeared in 1980 and was edited by D. A. KHARKEVICH, includes important aspects of autonomic cholinergic function.

Download or read book Insect Nicotinic Acetylcholine Receptors written by Steeve Hervé Thany and published by Springer Science & Business Media. This book was released on 2011-01-11 with total page 127 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this book is to summarize our understanding on the insect nicotinic acetylcholine receptors. This area of research received great impetus from the identification of the first subunit sequences to be used as neonicotinoid insecticide target sites. Although a book of this nature can provide the details only of commonly published results, it is hoped that it may provide a useful guide to the newcomer to the field as well as to point out some of the future challenges. For example, we need to determine the precise subunit nomenclature of insect nicotinic receptors. This nomenclature varies amongst species and this led to some of the early confusion that persists. We need to be precise in identifying the subunit composition of native insect nicotinic receptor subtypes, their functional properties and physiological roles.
Download or read book Pharmacology of Central Synapses written by V. V. Zakusov and published by Elsevier. This book was released on 2013-10-22 with total page 243 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pharmacology of Central Synapses deals with the pharmacology of the central nervous system and the mode of action of neurotropic drugs based on their influence on synaptic transmission. The neuronal structure of the nervous system, the structure of the synapses, and the phenomena of electrochemical transmission are discussed in this context. The main propositions of the synaptic theory of the action of neurotropic drugs, based on morphological, physiological, and biochemical findings, form the conceptual basis of this book. Comprised of eight chapters, this book examines the effect of neurotropic drugs on the synaptic transmission in reflex, projection, and association (commissural) tracts. The specific effects of various narcotics, neuroleptics, tranquillizers, analgesics, antidepressants, and stimulants on synaptic transmission in various structures of the central nervous system and at its different levels are described. This text also considers the differences in the sensitivity to such drugs of various synapses and their influence on the selectivity of drug action. This book explains the influence of neurotropic drugs on such aspects of nervous activity as impulse summation, after-discharge and functional lability, central inhibition, and the neurochemical mechanisms, particularly those involving monoaminergic, cholinergic, serotoninergic, and GABA-ergic components of synaptic transmission. The final chapter focuses on the effect of psychotropic drugs on behavior. This book will be helpful to scientists representing all the major areas of pharmacology, including clinical pharmacology and toxicology, as well as to internists, psychiatrists, neurologists, and anesthesiologists.

Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this book is to describe the memory system of the brain, taking into account all the levels of neural organization: molecule, cell, small network, and anatomical circuit. This synthetic approach is necessary for determining the real mechanisms among the potential ones, that is the neural bases of learning and memory in intact organisms functioning under normal conditions. For this purpose, data from molecular, cellular and behavioral neurobiology, neuropsychology, animal and human psychology, and neural modellization are comprehensively reviewed by leading specialists and brought together in an original synthesis.
Download or read book Magnesium in the Central Nervous System written by Robert Vink and published by University of Adelaide Press. This book was released on 2011 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: The brain is the most complex organ in our body. Indeed, it is perhaps the most complex structure we have ever encountered in nature. Both structurally and functionally, there are many peculiarities that differentiate the brain from all other organs. The brain is our connection to the world around us and by governing nervous system and higher function, any disturbance induces severe neurological and psychiatric disorders that can have a devastating effect on quality of life. Our understanding of the physiology and biochemistry of the brain has improved dramatically in the last two decades. In particular, the critical role of cations, including magnesium, has become evident, even if incompletely understood at a mechanistic level. The exact role and regulation of magnesium, in particular, remains elusive, largely because intracellular levels are so difficult to routinely quantify. Nonetheless, the importance of magnesium to normal central nervous system activity is self-evident given the complicated homeostatic mechanisms that maintain the concentration of this cation within strict limits essential for normal physiology and metabolism. There is also considerable accumulating evidence to suggest alterations to some brain functions in both normal and pathological conditions may be linked to alterations in local magnesium concentration. This book, containing chapters written by some of the foremost experts in the field of magnesium research, brings together the latest in experimental and clinical magnesium research as it relates to the central nervous system. It offers a complete and updated view of magnesiums involvement in central nervous system function and in so doing, brings together two main pillars of contemporary neuroscience research, namely providing an explanation for the molecular mechanisms involved in brain function, and emphasizing the connections between the molecular changes and behavior. It is the untiring efforts of those magnesium researchers who have dedicated their lives to unraveling the mysteries of magnesiums role in biological systems that has inspired the collation of this volume of work.
