    Synaptic Morphology
    • 1st Edition
    • Koji Uchizono
    • English
    Excitation and Inhibition: Synaptic Morphology proposes the S-F hypothesis that emphasizes the relationship between structure and function of synapses. This book begins with an introduction to the notion of inhibition in the physiology of the nervous system and history of “synapse”, followed by a discussion on the development of concept and morphological correlates of excitation and inhibition in relation to the S-F hypothesis. The mechanism of synaptic excitation and inhibition, physiological classification of neurons, and release mechanism of transmitters are also elaborated. This text describes the synaptic vesicles as a basis of transmitter, membrane recycle, transmission in the sympathetic ganglion, and transmitter substance. The criticism of S-F hypothesis, which deliberates the skeptical investigations of specialists regarding the simplicity and immaturity of the S-F hypothesis of synaptic morphology are provided at the end. This publication is beneficial to medical students and practitioners aiming to acquire knowledge of the physiology of synapses.
