Effect of the Stimulus Pulse Width upon the Stimuli-Response Characteristics of an Electronic Excitable Membrane Model

Abstract

Response characteristics of the electronic excitable membrane model by Tsukada, et al. to perodic pulse stimuli are investigated. Use of phase plane analysis and of phase transition curve extended by Maginu is made in order to clarify the characteristics. The global bifurcation structure of the model resembles to that of squid's giant axon. It is shown that the global bifurcation structure varies with stimulus pulse width. Shorter pulse width leads to simple behavior, and longer pulse width is likely to produce various behavior.
