Abstract

Irregular responses of Onchidium pacemaker neuron to a sinusoidal current stimulation are classified into three kinds of chaotic oscillations by means of one-dimensional stroboscopic and return maps: chaos, intermittency, and random alternative chaos. Harmonic responses bifurcate to the chaos through the intermittency or the random alternative chaos. All of the chaotic responses are caused by random jumps between two kinds of unstable harmonic responses. Two types of instability exist. Each combination of the two types of instability corresponds to each chaotic response. On the other hand, it is ascertained that spontaneous irregular activities of the neuron are really chaotic. One-dimensional maps of the activities reveal a single-valued function.
