Abstract(in English) | The response characteristics of the stable limit cycle oscillators which have the slow, fast dynamics to periodic pulsatile stimulation are investigated.Repetitive firing phenomenon with "spikting" dynamics as in the living pacemaker neu rons are modeled by the two oscillators with different complerities.Model′s global bifurcation diagrams are analyzed by u sing one dimensional map(PTC).In these oscillators,compaxing with non-spiking oscillators,the periodic points of small period of the PTC are stabilized against the variation of the period and intensity of stimulation,while chaotic regions in the parameter space are spread.Bistabilities are shown to be observable in the wide range of parameters.These facts are discussed qualitatively with the the dynamics of the membrane potential such as threshold, action potential and the sub-threshold voltage region activity of the neurons. |
