Histopbysiology of Synapses and Neurosecretion discusses the relationship between subcellular structure and function in synapses. The title discusses how neurosecretion phenomenon takes place in the important areas of central and peripheral nervous system. The first part of text deals with the synapse. Topics such as the concept of synaptic transmission, morphology of synaptic region, and ultrastructure of synaptic region are covered in the first part. Part I also discusses the MORPHO-physiological correlations in certain synapses; and neurochemical studies in isolated nerve endings and synaptic vesicles of the CNS. The second part of the selection covers neorosecretion. Part II tackles the neurohumoral mechanisms and secretion in the hypothalamicneurohypophysial system; secretory processes; and secretion in adrenergic nerves and endings. The book will be of great use to student, researchers, and practitioners of neurology.

The regulation of the organism has traditionally been ascribed to two distinct systems-the nervous and the endocrine. Though coordination between the two systems has been acknowledged, researchers and authors have tended to deal with them as comprising separate categories of cells involved in different activities. With this approach, a given regulatory mechanism would be evaluated as to whether it should be accounted for by nervous or endocrine functions. The past 15 years, however, have witnessed numerous important discoveries and conceptual developments concerning the morphological, physiological, and bio chemical relations between the nervous and endocrine systems. Advances in im munocytochemical studies have revealed that there are a wide variety of messenger substances that function in both regulatory systems. As a result, researchers have been stimulated to investigate neuronlike properties of endocrine cells and, con versely, endocrine or secretory features of neurons. It has thus become obvious that the rigidities in the classic criteria of neurotransmitters and hormones may rather impede further advances in these research fields. The activities of neurons are no longer evaluated simply in terms of EPSP, IPSP, and the release of classic trans mitters such as acetylcholine, noradrenaline, and GABA. Hormonal actions are no longer analyzed solely with regard to concentrations of classic aminic and peptidic hormones in the systemic blood circulation. The concept of the paraneuron, which we proposed in 1975, has become one of the theoretical bases for the development of this trend of study.

How do electrical activity and calcium signals in neurons influence the secretion of peptide hormones? This volume presents the current state of knowledge regarding the electrical, calcium signaling and synaptic properties of neuroendocrine systems from both vertebrate and invertebrate systems. The contributions span in vivo and in vitro studies that address: state‐dependent plasticity, relevance of firing patterns, membrane properties, calcium flux (including dynamic imaging and homeostasis), and molecular mechanisms of exocytosis, including from non-neuronal secretory cells. The chapters focus not only on research results but also on how experiments are conducted using state-of-the-art techniques, and how the resulting data are interpreted. While there are many books on the secretory properties of neurons, this is the first to focus on the distinctive secretory properties of neuroendocrine neurons. Accordingly, it offers an important text for undergraduate and graduate neuroscience students, and will also appeal to established scientists and postdoctoral fellows. This is the eighth volume in the Masterclass in Neuroendocrinology series* - now a co-publication between Springer Nature and the INF (International Neuroendocrine Federation). *Volumes 1-7 published by Wiley

Intended for use by advanced undergraduate, graduate and medical students, this book presents a study of the unique biochemical and physiological properties of neurons, emphasising the molecular mechanisms that generate and regulate their activity.

This book is designed as an introductory text in neuroendocrinology; the study of the interaction between the brain and endocrine system and the influence of this on behaviour. The endocrine glands, pituitary gland and hypothalamus and their interactions and hormones are discussed. The action of steroid and thyroid hormone receptors and the regulation of target cell response to hormones is examined. The function of neuropeptides is discussed with respect to the neuroendocrine system and behaviour. The neuroimmune system and lymphokines are described and the interaction between the neuroendocrine and neuroimmune systems discussed. Finally, methods for studying hormonal influences on behaviour are outlined. Each chapter has review and essay questions designed for advanced students and honours or graduate students with a background in neuroscience, respectively.

Having accepted the task to organize, in Amsterdam, an international Congress in behalf of the International Sodety for Neurovegetati'V'e Research such as is held every second year, it occurred to me that it might be worth while to change its usual pattern somewhat. Instead of giving merely the opportunity for l'eading a nurnber of rather short free papers, more or less grouped in many categories, we decided to start with a symposium on a special topic 'to be dealt with from several aspects by a numbe·r of invited speakers, the last day of the congress being only available for short free communications. The central topic for the symposium finally chosen was "Neurohormones and N eurohumors" as this subject is of interest :to many morphologists, physiologists, pharmacologists, neuro-endocrinologists, biochemists and clini cians, and belongs to a rapidly expanding Held of research. Moreover, it appeared to us that there is some confusion about the defini tion of these terms which are not seLdom used indifferently. I hoped that such a symposium would contribute 1to a clearer apprehension of the terms based on morphological, physiological and biochemical criteria as well as to a clearer understanding of some problems involved which will have to be subjects of future investigations.

It has been known for half a century that neurotransmitters are released in preformed quanta, that the quanta represent transmitter-storing vesicles, and that release occurs by exocytosis. The focus of this book is twofold. In the first part, the molecular events of exocytosis are analysed. In the second part of the book, the presynaptic receptors for endogenous chemical signals are presented that make neurotransmitter release a highly regulated process.

Comparative Endocrinology, Volume II, Part One: Invertebrate Hormones: Tissue Hormones provides readers with some basic knowledge of animal morphology, physiology, and chemistry; a systematic and comprehensive account of endocrine principles from the comparative point of view. It can therefore be hoped to present a critical and up-to-date picture of the comparative aspects of endocrinology to the medical scientist and zoologist generally, and to furnish an adequately documented background to the research worker who is beginning to take an interest in one of the many endocrine systems described. The subject matter has been divided into three sections. The largest—which forms the contents of the first volume—deals with hormones originating in well-defined glandular organs and tissues and also reviews the relationships between the central nervous system and these endocrine complexes. The second section (Volume II, Part 1) discusses hormonal systems of invertebrates, and the third (Volume II, Part 2) contains a description of neurohormones and tissue hormones.
