Book excerpt: Comparative Neurochemistry, a collection of papers presented at the Fifth International Symposium of Comparative Neurochemistry, held at St. Wolfgang, Austria in 1962, deals with variations in neurochemical mechanisms in different animal species. The book integrates the data derived from comparative studies in different disciplines and assesses their significance in relation to the understanding of nervous mechanisms in animals, including human. The papers are grouped into sections, which cover general topics on functional organization in different species; lipids, proteins, and ribonucleic acid; amino acids in different species; energy metabolism and function; neurosecretory mechanisms; and comparative neuropharmacology. The text will be of interest to biologists, zoologists, pharmacologists, chemists, neurologists, and researchers in the pharmaceutical and chemical industries.

Available in PDF, EPUB and Kindle. Book excerpt: The attractions of invertebrate nervous systems have long been appreciated by neurophysiologists. Indeed some of the milestones in our understanding of nervous systems have their foundations in experiments done on invertebrate preparations, typified by the role of the squid axon in dissect ing the events that constitute the action potential. More recently we have seen how the relatively simple nervous system of Aplysia has permitted new insights into the molecular mechanisms of memory and learning. Neurochemists, however, have not been enthusiastic about invertebrate tissues as their experimental material. Much of the biochemical information on invertebrate nervous systems that has accrued has been incidental, almost as a by-product of what were primarily physiological investigations. Fortunately the field is changing, and research groups are making a positive choice to turn to invertebrate tissues. Two important factors have contributed to this. First, the study of analogous systems in invertebrates and vertebrates can tell us much about the evolution of nervous systems. The application of the techniques of molecular genetics to the study of such molecules as receptors and ion channels can provide detailed information about their composition that, in turn, allows us to better understand their function. By extending such studies to the invertebrates we should be able to understand how such systems have developed. Secondly, invertehrate pests are responsible for enormous losses of agricultural crops and are major vectors of disease in man.

This book was released on 2013-12-14 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: Comparative neurological studies of the evolutionary development of struc tures within the central nervous system of vertebrates have depended to a large extent upon morphological rather than functional criteria. Classical comparative anatomical studies, which have attempted to demonstrate homologies between parts of the brain in representatives of different vertebrate classes may be grouped under three general headings: 1. comparison of the embryological development of brain structures; 2. comparison in adult forms of the topographical relations of neuron groupings and fiber tracts, and of the morphology of cell types ( cyto architectonics); and 3. analysis and comparison of fiber connections between particular cell groupings or regions. Of these three, the third encompasses func tional relationships most directly, but even in well-defined fiber tracts the direction of conduction often remains indefinite, and the extent and activity of more diffuse systems is poorly known. In recent years a nurober of investigations applying electrophysiological and degeneration methods to submammalian forms have been reported. Those most pertinent to the present studies include the papers of . ARMSTRONG et al. (1953), KRUGERand associates (e. g. HERIC and KRUGER, 1966; KRUGERand BERKOWITZ, 1960; PowELL and KRUG ER, 1960}, GusEL'NIKov and SUPIN (1964) and KARA MYAN and BELEKJIOVA (1964) on various reptiles, and of PowELL and CowAN (1961), KARTEN and REVZIN (1966) and REVZIN and KARTEN (1967) on the pigeon.

Available in PDF, EPUB and Kindle. Book excerpt: It is generally accepted that all living organisms present on earth derive from one single primordial cell born several billion years ago. One important step in the evolution occurred some 1. 5 billion years ago with the transition from small procaryote cells with relatively simple internal structures such as bacteria to larger and more compleX: eucaryotic cells such as those found in higher animals and plants. Large membrane proteins which enable the cells to communicate appeared early in evolution, and it is believed that the nerve membrane receptors and ionic channels which are observed today in both invertebrate and vertebrate species derive from a common ancestor. Basically, the three identified superfamilies, 1) ionotropic receptors (i. e. receptors containing an integral ionic channel), 2) metabotropic receptors (receptors coupled to G proteins) and 3) voltage-dependent ionic channels (Na+, K + and Ca2+ channels) were already well differentiated when vertebrates separated from invertebrate species. The large number of subtypes which are observed in each superfamily may be of more recent evolutionary origin. To understand how this happened, the best approach was to compare the sequences and the properties of the receptors and ionic channels in species sufficiently distant in the evolutionary tree. In the present volume, many of the best specialists in the field of comparative molecular neurobiology, several of them working on vertebrate and invertebrate species, have accepted to report their most recent findings.

Available in PDF, EPUB and Kindle. Book excerpt: This application of comparative neurobiology examines a variety of vertebrates and invertebrates to delineate the neural processes of each in relation to its environment. Focusing on modes of communication within the nervous system itself and between the organism and its environment, the contributors address the fundamental topics of how nervous systems are constructed and organized, the interactions among their components, and how behavior is generated. Beginning with the development and plasticity of the nervous system, it covers modes of communication between cells processing data in the brain, as well as integrative brain processes that generate and control motor activity and behavior.

Book excerpt: This volume is one of those published from the proceedings of the invited lectures to the First International Congress of Comparative Physiology and Biochemistry I organized at Liege (Belgium) in August 1984 under the auspices of the Section of Comparative Physiology and Biochemistry of the International Union of Biological Sciences. In a general foreword to these different volumes, it seems to me appropriate to consider briefly what may be the comparative approach. Living organisms, beyond the diversity of their morphological forms, have evolved a widespread range of basic solutions to cope with the different problems, both organismal and environmental with which they are faced. Soon after the turn of the century, some biologists realized that these solutions can be best comprehended in the frame work of a comparative approach integrating results of physiological and biochemical studies done at the organismic, cellular and molecular levels. The development of this approach amongst both physiologists and biochemists remained, however, extremely slow until recently.

Available in PDF, EPUB and Kindle. Book excerpt: The Scientific Basis of Drug Therapy in Psychiatry is a collection of papers that covers the therapeutic effects and the mode of action of the various psychotropic drugs. The materials in the title are organized thematically based on the topic they tackle. The text first covers the articles on the basic concepts, such as anatomy and physiology of the emotions and their relation to psychoactive drugs, as well as the methods of assessment of psychological effects of drugs. The next three chapters cover the concerns with the psychotropic drugs that include clinical use, mode of actions, and pharmacology. The remaining paper talks about some of the considerations that need to be taken when administering psychotropic drugs. The book will be of great use to researchers and practitioners in behavioral science related disciplines, such as psychology, psychiatry, and neurology. Pharmacologists and medicinal chemists will also benefit from the text.
Download or read book Frog Neurobiology written by R. Llinas and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 1056 pages. Available in PDF, EPUB and Kindle. Book excerpt: In review, the amount of information available on the morphological and func tional properties of the frog nervous system is very extensive indeed and in certain areas is the only available source of information in vertebrates. Further more, much of the now classical knowledge in neurobiology was originally ob tained and elaborated in depth in this vertebrate. To cite only a few examples, studies of nerve conduction, neuromuscular transmission, neuronal integration, sense organs, development, and locomotion have been developed with great detail in the frog and in conjunction provide the most complete holistic descrip tion of any nervous system. Added to the above considerations, the ease with which these animals may be maintained (both as adults and during development) and the advantage of their lower cost as compared with other vertebrate forms make the frog one of the most important laboratory animals in neurobiology. With these thoughts in mind, we decided to compile this volume. Our goal in doing so was to assemble as much as possible of the information available on frog neurobiology and to have the different topics covered by authorities in each of the fields represented. To keep the handbook restricted to one volume, we found it necessary to omit the large field of amphibian muscle neurobiology, which has already been summarized in various other publications.

Book excerpt: Biochemistry of Brain is a collection of articles dealing with the developments in the biochemistry of the brain. This book gives a comprehensive and critical discussion of important developments in studies concerning the above subject. This text discusses the structure, function, and metabolism of glycosphingolipids, which are related to the study of sphingolipid storage diseases. Inborn defects of metabolism are found in Gaucher's and Fabry's disease, which are characterized by lipid accumulation in the brain. Another paper reviews the chemical and genetics of critically lysosomal hydrolase deficiencies that can cause the storage of sphingolipids. This book then explains the role of myelin basic protein in lipids in vivo that the weak bonding of the protein is not a major component of myelin stability. Another paper discusses the procedures for isolating subfractions of myelin and myelin-related membranes, with some attention given on the alterations in the subfractionation of myelin in pathological hypomyelinating and demyelinating conditions. Another article discusses the biochemical and enzymatic composition of lysosomes and the biosynthesis, intracellular transport, storage, and the degradation of lysosomal constituents. This collection of papers will benefit scientists doing research in microbiology, microchemistry, molecular genetics, and neurochemistry.

This book was released on 2012-12-06 with total page 724 pages. Available in PDF, EPUB and Kindle. Book excerpt: Few can deny the paramount importance of the neurosciences, undoubtedly one of the most challenging fields in contemporary science. Recent years have witnessed the awakening of interest in brain research by many dis tinguished investigators from other branches of science, which has made possible the multidisciplinary approach needed for the complex problems of this field. The present book, which deals with one aspect of this research, is the result of the symposium held under the auspices of the New York State Research Institute for Neurochemistry and Drug Addiction in April 1968. It has become clear that brain proteins are involved in all aspects of mental function and dysfunction, and the present volume documents the latest advances in our knowledge (advances made to a large extent by con tributors to this volume). The chapters not only convey some of the enthu siasm and wonderful, cooperative spirit of the many excellent scientists ex ploring the brain, and their wealth of ideas; they also illustrate the many approaches from which cerebral proteins can be studied in a meaningful manner. In some areas even preliminary evidence is worth discussing: e.g., it is an exciting achievement that we can begin to apply the disciplines of bio chemistry to phenomena of learned behavior and information handling.
