title: Currents and channels in the presynaptic nerve terminal.
abstract: Synaptic transmission is a key element in neuronal communication in the nervous system. It is determined by two basic sets of processes: release of transmitter from the presynaptic nerve ending and the detection and response by the postsynaptic cell. The release of transmitter is crucially dependent on the interplay among the ion channels in the surface membrane of the presynaptic terminal. In this article we describe the methods used in the study of the ion channels in secretory nerve endings and present the 16 calcium, sodium, chloride, cationic and potassium ion channels discovered in various preparations. We speculate about the physiological and pathophysiological roles of some of these ion channels.
