The present review is based on the data of the literature, and on the personal experience gained by the author in recent years by studying the histogenesis of spinal ganglia. Probably, the reader will find more than one gap in the biblio graphy. The author would like to point out that in no case are such gaps due to the voluntary omission of any information, interpretations, or views. The gaps are due only to the difficulties met in trying to master such a vast literature consisting of so many contributions which have appeared over more than a century. An endeavour has been made to report not only the morphological data, but also, whenever possible, information derived from histochemical and biochemical studies. 11. Origin 01 the Spinal Ganglia Before 1868 it was generally thought (see, e.g., Remak, 1851; Bidder and Küpffer, 1857) that the spinal ganglia arise from the mesoblast of the protoverte brae (old term for somites). In 1868 His showed that the nerve cells of the spinal ganglia take their origin from the ectoderm, and more precisely from a thin band of ectoderm (Zwischenstrang, neural crest) flanking each side of the neural plate (Fig. 1 a) and interposed between it and the somatic ectoderm (Hornblatt). On this subject His (1879) wrote in a later paper " ... die spinalen Ganglien ... aus einem schmalen Substanz streifen hervorgehen, welche zwischen der Medullarplatte und dem Hornblatte gelegen ist und dessen Material ich als Zwischenstrang bezeichnet habe."

In our attempts to interrogate Nature about the development of the nervous system, we ask such questions as "How do the nerve cells originate and how do the correct types of cells differentiate at their correct positions; how do the neurons link together to form circuits whose functions are properly coordinated; and how are the functions of nerve cells related to behavior, to thought, and to conscious ness?" Those problems are intellectually challenging, not only because solving them would give us practical advantages but also because while they remain unsolved they stimulate the imagination and challenge the intelligence. It is precisely because they are difficult and controversial and have defied complete solution that such problems continue to attract subtle minds. The understanding that we now have of neural ontogeny seems to me to be farther from complete knowledge than from total ignorance. Nonetheless, it gives us a slightly elevated position from which to survey the vicissitudes of the past, to appraise our present understanding, and to consider ways in which our knowl edge might develop in the future. The history of this subject affords a particularly piquant illustration of Arthur Lovejoy's comment that the "adequate record of even the confusions of our forebears may help, not only to clarify those confu sions, but to engender a salutary doubt whether we are wholly immune from different but equally great confusions.

This book is in many ways a sequel to The Biochemistry ojGlycoproteins and Proteoglycans. The enormous recent progress in understanding the biological roles of glycoproteins has prompted the present volume. The reasons for studying glycoproteins have multiplied, and in the present volume the roles played by glycoproteins are explored in a variety of biological situations. The first two chapters describe molecules involved in cell-substratum and cell-cell interactions in a broad sense, and also focus on recent progress in identifying specific attachment molecules. Our understanding of how normal processes, such as cellular differentiation and tissue organization, are regulated is dependent on understanding how cells interact with the extracellular matrix. When these processes go awry the consequences can be tragic, for example, when manifest as birth de fects and cancer. Our ability to devise appropriate therapies is in many cases limited by our understanding of such cell-matrix interactions. The third chapter explores the roles by glycoproteins during early mammalian development. The carbohydrate portions c1early play very important roles in presenting information during early embryogenesis, and an unusual tumor stern cell, the embryonal carcinoma, looks very promising in pro viding an experimental system for understanding how the expression of these complex carbohydrate determinants is regulated. The next three chapters explore the biology of glycoproteins in distinct situations: in the immune system, in the nervous system, and during erythropoiesis.

Progress in developmental neurobiology and advances in (neuro) genetics have been spectacular. The high resolution of modern imaging techniques applicable to developmental disorders of the human brain and spinal cord have created a novel insight into the developmental history of the central nervous system (CNS). This book provides a comprehensive overview of the development of the human CNS in the context of its many developmental disorders. It provides a unique combination of data from human embryology, animal research and developmental neuropathology, and there are more than 400 figures in over a hundred separate illustrations.

This book is unique in that it provides the reader with the most up-to-date terminology used to describe the human nervous system (central and peripheral) and the related sensory organs, i.e., the Terminologia Neuroanatomica (TNA), the official terminology of the IFAA (International Federation of Associations of Anatomists). The book provides a succinct but detailed review of the neuroanatomical structures of the human body and will greatly benefit not only various specialists such as (neuro)anatomists, neurologists and neuroscientists, but also students taking neuroanatomy and neuroscience courses. The book offers a high yield, combined presentation of neuroanatomical illustrations and text and provides the reader a ‘one-stop source’ for studying the intricacies of the human nervous system and its sensory organs. It includes an alphabetical list of official English terms and synonyms with the official Latin terms and synonyms from the TNA. With regard to the entries, the name of the item in standardized English is provided, followed by synonyms and the official TNA Latin term, Latin synonyms and eponyms, a short description and in many cases one or more illustrations. To facilitate the use of illustrations, certain entries such as the gyri or sulci of the cerebral cortex are presented together with extensive cross-references. Terms that form part of a certain structure (such as the amygdaloid body, the thalamus and the hypothalamus) are listed under the respective structure. Segments and branches of arteries are discussed under the main artery, for example the A1–A5 segments under the anterior cerebral artery. Most nerves can be found following their origin from the brachial, cervical and lumbosacral plexuses. However, the major nerves of the limbs are discussed separately, as are the cranial nerves. Nuclei can be found by their English name or under Nuclei by their eponym.

Series on Mental Retardation held in Oxnard, California, in January 1974. This book compiles research on neurobiological findings which might lead to an understanding of the basic processes underlying the phenomena of mental deficiency and related aspects of human development. The topics discussed include the timing of major ontogenetic events in the visual cortex of the rhesus monkey; neuronal sprouting after hippocampal lesions; synaptic and dendritic development and mental defect; and CNS maturation and behavioral development. The neuronal control of neurochemical processes in the basal ganglia; nigrostriatal projections and the "dopamine receptor; and effects of caudate nuclei removal in cats are also deliberated. This text likewise covers the effects of caudate nuclei removal versus frontal cortex lesions in kittens and role of biochemistry in research on mental retardation This publication is beneficial to medical practitioners and students concerned with mental retardation.

This 1999 edition of The Neural Crest contains comprehensive information about the neural crest, a structure unique to the vertebrate embryo, which has only a transient existence in early embryonic life. The ontogeny of the neural crest embodies the most important issues in developmental biology, as the neural crest is considered to have played a crucial role in evolution of the vertebrate phylum. Data that analyse neural crest ontogeny in murine and zebrafish embryos have been included in this revision. This revised edition also takes advantage of recent advances in our understanding of markers of neural crest cell subpopulations, and a full chapter is now devoted to cell lineage analysis. The major research breakthrough since the first edition has been the introduction of molecular biology to neural crest research, enabling an elucidation of many molecular mechanisms of neural crest development. This book is essential reading for students and researchers in developmental biology, cell biology, and neuroscience.
