Abstract

The authors consider the determination of conditions when an excitable membrane can be considered linear and steady-state. The following topics are dealt with: threshold for a space-clamped fiber; threshold for a fiber stimulated by a point current source; subthreshold response; passive vs. active response; defibrillation stimulus-response time-constant; the transient intracellular current; the transient transmembrane potential due to junctional resistance.
