Synaptic transmission plays a central role in the nervous system as the mechanism that allows for chemical and electrical communication between cells and thus connects discrete elements into the functioning whole. This is a broad account of anatomical, biochemical, embryological, medical, pathological, pharmacological, and physiological studies on synaptic transmission during the hundred years beginning in 1890. During this century, the process of synaptic transmission came to be recognized not only as the most fundamental neurophysiological process, but also as a seat of pathological changes, and as the predominant site of action for drugs used to treat a wide range of psychiatric and neurological disorders. At the same time, research from these various disciplines was transformed into a new and unifying field, neuroscience. The course of these investigations reveals ingenious experiments, powerful new techniques, and imaginative insights. The author describes broadly who did what, when, where, and how (and, in cases where it is apparent, why) and uses experimental results and interpretations to display the evolutionary course to our current understanding of how nerve cells communicate: the basic principle of neural functioning. The book will be of interest to basic and clinical neuroscientists, pharmacologists, and physiologists, to historians and philosophers of the life sciences and medicine, and to their respective students.

This book provides the reader with background information on neurotransmitter release. Emphasis is placed on the rationale by which proteins are assigned specific functions rather than just providing facts about function.

Neurons in the nervous system organize into complex networks and their functions are precisely controlled. The most important means for neurons to communicate with each other is transmission through chemical synapses, where the release of neurotransmitters by the presynaptic nerve terminal of one neuron influences the function of a second neuron. Since the discovery of chemical neurotransmission by Otto Loewi in the 1920s, great progress has been made in our understanding of mol- ular mechanisms of neurotransmitter release. The last decade has seen an explosion of knowledge in this field. The aim of Molecular Mechanisms of Neurotransmitter Release is to provide up-to-date, in-depth coverage of essentially all major mole- lar mechanisms of neurotransmitter release. The contributors have made great efforts to write concisely but with sufficient background information, and to use figures/diagrams to present clearly key concepts or experiments. It is hoped that this book may serve as a learning tool for neuroscience students, a solid reference for neuroscientists, and a source of knowledge for people who have a general interest in neuroscience. I was fortunate to be able to gather contributions from a group of outstanding scientists. I thank them for their efforts. In particular, I want to thank Dr. Erik Jorgensen who offered valuable suggestions about the book in addition to contrib- ing an excellent chapter. I thank US National Science Foundation and National Institute of Health for their supports.
