Action Potentials

Abstract

A simple cellular electrophysiological model is that shown in Fig. 5.1. Here the cell membrane separates the extracellular and intracellular spaces. Both regions may be idealized as passive and uniformly conducting (though with different conductivities). If an adequate stimulating current is passed between a pair of electrodes at the surface of the cell, then an action potential is elicited. From an initial site the action potential will propagate to all parts of the cell. This chapter is devoted to a quantitative examination of these observations.
