Typical dynamics of bifurcating neurons with double base signal inputs

Abstract

This paper studies the bifurcating neuron whose base signal consists of fundamental and third harmonic components. The BN can exhibit a variety of bifurcation phenomena which are impossible in the case of single component. For example, periodic spike-train in the single component is changed into co-existence states of chaotic and periodic spike-trains in the double components. Using the mapping procedure, such phenomena are analyzed precisely. Presenting a simple test circuit, typical phenomena are investigated experimentally.
