AN ANALYSIS OF THE STRIATED MUSCLE FIBER ACTION CURRENT.

Abstract

A method is presented for determining the magnitude of the ionic current associated with the propagated spike potential. Parameters of the action current are then compared to various aspects of the response as recorded in a phase plane. The findings also include evidence for (a) Na(+) ion as the major inward current carrier, (b) a fairly constant membrane conductance during the terminal phase ( approximately 1 msec.) of the spike potential, and (c) the influence of Ca(++) ion concentration on the action current.
