In the unstressed adult preparation (frogs and mammals) most MEPPs (96%) contribute to a bell-shaped distribution (bell-MEPPs) which has a coefficient of variance of about 30% (Fatt and Katz, 1952). Del Castillo and Katz (1954) showed that the unitary evoked potent

Control of the Generation and Removal of Calcium-Mediated Inactivation of the Calcium Current in , Nolarizing activity in excitable cells activates voltage-dependent calcium currents (Hagiwara and Byerly, 1981; Tsien 1983: McCleskey et al., 1986), which can be regenerative, resulting in a rapid increase in the activity of intracellular calcium ions in the vicinity of the channel. The elevation in

Cytoplasmic Modulation of Ion Channel Functioning in the Neuronal Membranexperimental data have become available indicating that in certain cases the function of ion channels may be directly influenced by intracellular metabolic processes. The present paper presents a survey of such data obtained in our laboratory and discusses their significance for the understanding of cell functioning.
