Available in PDF, EPUB and Kindle. Book excerpt: An ontogenetic study of the central nervous system is an important tool for the under standing of its morphological and morpho-functional relations. Numerous qualitative results on the ontogenesis of the visual system can be found in the literature, but there are only very few quantitative results fulfilling the following parameters: (1) samples of sufficient size; (2) measurements considering results of stereology; (3) evaluation and interpretation performed with sound biomathematical methods; (4) quantitative of the shrinkage caused by the histological technic. The first three results independent demands can be fulfilled by using available computerized stereological and biomathe matical methods (Kretschmann and Wingert, 1968, 1969a, b, c, 1971; Wingert, 1969; Zilies and Wingert, 1972; Zilies et al., 1976a, c, d). The interdisciplinary cooperation between morphologists and mathematicians makes possible the analysis of the volume growth, the number of nerve-and glial cells in a whole brain region (Schleicher et al., 1975a, b; Zilies and Wingert, 1973a, b; Zilies et al., 1974, 1975a, b), the semi-automatic analysis of the nucleolar diameters in nerve cells (Zilies et al., 1976b) and computer aided compartment analysis with the point counting method (Zilies et al., in press b). Tupaia belangeri, an interesting animal for neurobiologists, was the experimental animal of choice because it combines the advan tages of a small brain (conducive to rapid processing) with many characteristics of the of the primate brain.
Download or read book Development of the Visual System written by Retina Research Foundation (U.S.). Symposium and published by MIT Press. This book was released on 1991 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: Development of the Visual System presents a selection of current studies that clearly illustrate principles of visual system development. These range from retinal development in fish and frogs to the effects of abnormal visual experience on the primary visual cortex of the cat. The book is unique in addressing four specific and fundamental aspects of development: cell lineage and cell fate, specificity and targeting of axons, specification of visual cortex, and correlates of the critical period. Encompassing technical advances in cellular and molecular biology and in video imaging and microscopy, contributions in each of these areas provide new information at the cellular and molecular levels to complement the now classic descriptions of visual development previously available at the level of neural systems.ContributorsKaren L.

Download or read book Vertebrate Photoreceptors written by Takahisa Furukawa and published by Springer. This book was released on 2016-08-23 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a series of comprehensive views on various important aspects of vertebrate photoreceptors. The vertebrate retina is a tissue that provides unique experimental advantages to neuroscientists. Photoreceptor neurons are abundant in this tissue and they are readily identifiable and easily isolated. These features make them an outstanding model for studying neuronal mechanisms of signal transduction, adaptation, synaptic transmission, development, differentiation, diseases and regeneration. Thanks to recent advances in genetic analysis, it also is possible to link biochemical and physiological investigations to understand the molecular mechanisms of vertebrate photoreceptors within a functioning retina in a living animal. Photoreceptors are the most deeply studied sensory receptor cells, but readers will find that many important questions remain. We still do not know how photoreceptors, visual pigments and their signaling pathways evolved, how they were generated and how they are maintained. This book will make clear what is known and what is not known. The chapters are selected from fields of studies that have contributed to a broad understanding of the birth, development, structure, function and death of photoreceptor neurons. The underlying common word in all of the chapters that is used to describe these mechanisms is “molecule”. Only with this word can we understand how these highly specific neurons function and survive. It is challenging for even the foremost researchers to cover all aspects of the subject. Understanding photoreceptors from several different points of view that share a molecular perspective will provide readers with a useful interdisciplinary perspective.

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.
Download or read book The Changing Visual System written by P. Bagnoli and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 414 pages. Available in PDF, EPUB and Kindle. Book excerpt: In late May and early June 1991, a NATO Advanced Study Institute was held at a hotel in the hilltop village of San Martino al Cimino a few kilometers from the city of Viterbo in the Lazio region of Italy. The title of the course was the same as this volume and brought together specialists working at all phases of the life span (embryology, infancy, childhood, middle life and senescence) in both animals and humans to exchange ideas, facts and theories in the search for common principles. Such principles could prove important for understanding developmental changes in the central nervous system and visual behavior within the context of a continuum of life-span processes rather than viewing them as events or mechanisms that occur only in a certain period. For example, changes that are associated with "aging" were considered as extensions or continuations of processes that began at an earlier stage of the life span, rather than being seen as processes that only began late in life.

This book was released on 2012-12-06 with total page 157 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a timely opus. Most of us now are too young to remember the unpleasant ring of a polemic between those who produced "hair-splitting" parcellations of the cortex (to paraphrase one of O. Vogt's favourite expressions) and those who saw the cortex as a homogeneous matrix sus taining the reverberations of EEG waves (to paraphrase Bailey and von Bonin). One camp accused the other of producing bogus preparations with a paint brush, and the other way around the accusation was that of poor eye-sight. Artefacts of various sorts were invoked to explain the opponent's error, ranging from perceptual effects (Mach bands crispening the areal borders) to poor fixation supposedly due to perfusion too soon (!) after death. I have heard most of this directly from the protagonists' mouths. The polemic was not resolved but it has mellowed with age and ultimately faded out. I was relieved to see that Professor Braak elegantly avoids dis cussion of an extrememist tenet, that of "hair-sharp" areal boundaries, which makes little sense in developmental biology and is irrelevant to neurophysiology. It was actually detrimental to cortical neuroanatomy, since its negation led to the idea that structurally distinct areas are not at all existent. Yet, nobody would deny the reality of five fingers on one hand even if the detailed assignment of every epidermal cell to one finger or another is obviously impossible.
Download or read book The Neocortex written by Wolf Singer and published by MIT Press. This book was released on 2019-10-29 with total page 449 pages. Available in PDF, EPUB and Kindle. Book excerpt: Experts review the latest research on the neocortex and consider potential directions for future research. Over the past decade, technological advances have dramatically increased information on the structural and functional organization of the brain, especially the cerebral cortex. This explosion of data has radically expanded our ability to characterize neural circuits and intervene at increasingly higher resolutions, but it is unclear how this has informed our understanding of underlying mechanisms and processes. In search of a conceptual framework to guide future research, leading researchers address in this volume the evolution and ontogenetic development of cortical structures, the cortical connectome, and functional properties of neuronal circuits and populations. They explore what constitutes “uniquely human” mental capacities and whether neural solutions and computations can be shared across species or repurposed for potentially uniquely human capacities.

This book was released on 2012-12-06 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: This century has witnessed the creation of new sciences extending the frontiers of knowledge to an unprecedented degree. We have seen the birth of cybernetics and bionics, bringing together such apparently distantly related branches of science as neurohistology and automation, synaptology and electronics. The electron microscope has resolved tissues almost down to the molecular level, and histochemistry has led to the fine analysis of brain structure. However, before these and other new sciences can develop properly and scientifically, a precise knowledge of the structure of the material with which they are concerned is absolutely essential. That is why the need exists at the present time for a detailed study of the larger units, i. e. , the neurons, their interrelationships and the pathways by which excitation is conducted. Biologists, neurologists, physicists, and specialists in other technical disci plines will find this study highly useful. During recent years many advances have been made in knowledge of the central visual system and its pathways. Above all, it has been found that the visual system is very extensive. The optic tract is connected, not only with the lateral geniculate body, but with the superior colliculus and the pulvinar. Besides the discovery of these principal pathways, connections have also been studied with the hypothalamus, the pretectal region, the medial geniculate body, subthalamus, and other parts of the brain stem. The visual system is thus connected with the reflex apparatus, the autonomic nervous system, and the auditory and reticular systems.
