Original study and a review of the pertinent literature are presented in this monograph on the early development of the neopallial wall and the choroidal area in vertebrates before the appearance of nerve cells. In the pre-neural period the telencephalic wall is a cohesive, non-stratified epithelial sheet of elongated, radially oriented, polarized cells. Although these cells, including the radial glial cells, differ from each other in various regions and change in shape, internal structure and phenotypic expression during development, they have a basic unity. The book draws attention to this unity and discusses the cells' morphogenesis and functions, and the mechanisms which help to shape the early cerebral hemispheres. The pre-neural period is of fundamental importance for the development of the cerebrum. The knowledge presented here of how cells differentiate during the early stages will help neuroscientists by providing a basis for comparisons with cultured cells and explants, and with cells seen in lineage studies and with microscopic observations of living animals in which dynamic events in the CNS can be seen directly. This work will improve our understanding of many developmental abnormalities of the nervous system.

It is well established that glial cells represent more than mere passive cytoskeletal support elements of the central and peripheral nervous system. A reciprocal relationship exists between neurons and glia that is vital for mutual differentiation, development, and functioning of both cell types. It also has become apparent that perturbations in glial function may lead to deleterious consequences in juxtaposed neurons. It is therefore possible that neuronal damage induced by chemicals or neuropathic disease involves dissociation of glial-neuronal interactions. The Role of Glia in Neurotoxicity brings together experts in the neurosciences to provide a more complete understanding of the effects of chemicals on nervous system function. This book explores potential sites of glial-neuronal interactions both in the central and peripheral nervous system, focusing on potential sites of neurotoxicant actions. Text introduces basic aspects of neuroscience, the first step toward understanding the mechanisms at work in normal physiology. The ways in which these processes are disturbed in pathological conditions are discussed. Distinguished authors examine the functional interactions between glial cells and neurons during development, adulthood, and senescence. The roles of glia in the normal CNS and PNS are described. The book offers specific, in-depth examples of directly (via diffusive and cell surface signals) or indirectly (via effects on the extracellular fluid or the blood-brain barrier) mediated glial neurotoxicity. This reference includes different techniques, conceptual frameworks, and approaches that are currently used in the study of the role of glia in neurotoxicity. This timely review not only presents an excellent overview of the state of the science but also provides direction for future research into the consequences of an altered glial-neuronal unit.

In the present work, processes of cell proliferation, cell death, neurogenesis, and gliogenesis in the mouse hippocampus were studied. The mapping of distribution of hippocampal mitoses and counting of their number allowed a more precise definition of the data concerning the disposition and age reduction of proliferative sites in Ammon's horn and the dentate gyrus in the mouse. As a result, the following generalized scheme of development and age reduction of the germinal zones in the mouse hippocampus has been suggested. 1. Ammon's horn a) The ventricular zone, from the beginning of formation of the hippocampus (Ell) until E20 b) The suprafimbrial zone, from El6 until P7 2. Dentate gyrus a) The prime germinal zone ("the anlage of the dentate gyrus" of Stanfield and CowanI979b), from E15 until P3 b) The proliferative zone of the hilus, from P3 until Pl4 c) The subgranular zone, from P3 until adult age The adduced scheme needs some comments: 1. In the hippocampus (as well as in other formations of the developing brain), primary precursors of all types of cells of neuroectodermal origin are represented by cells of the ventricular zone. They give rise to cells of secondary germinal zones in the dentate gyrus and Ammon's horn and are direct precursors of the majority (if not of all) neuronal cells in Ammon's horn, the earliest originating generations of neurons in the dentate gyrus, hippocampal radial glial cells, and, evidently, of a considerable part of astroblasts and oligodendroblasts in Ammon's horn.

Astrocytes: Cell Biology and Pathology of Astrocytes, Volume 3 deals with the involvement of astrocytes in neurological and neuropathological states of brain function. This volume discusses the expression of astrocyte-specific immunological markers and plasma membrane structures; the dynamics of the cytoskeleton and cell cycle; and the reactivity to injury and response of astrocytes in selected pathological and genetic states. The text also aims to inspire new ideas and research on astrocyte functions as well as on the pathogenesis of neurological disorders. Neuroscientists, cell biologists, clinicians, neuropathologists, and pediatric neurologists will find the book invaluable.

This book represents the most complete and authoritative description on the fine structure of the nervous system available in a single volume. Beginning with background material on the neuron, the book then examines specific portions of the nerve cell, and of the various supporting cells. Structure is first described in a general fashion, followed by detailed coverage of the fine structure of each component, with full discussion of how the structural features relate to their functions. Extensively revised and rewritten, this book will bring readers up to date with the many important developments that have taken place since publication of the previous edition. It includes over 130 electron micrographs and line drawings, many of which are new to this edition.
