Local stability results for the collective behaviors of infinite populations of pulse-coupled oscillators
2011
IEEE Conference on Decision and Control and European Control Conference
Preserved Fulltext
In addition to recovering known stability results of finite populations, we also obtain new stability results for infinite populations. ...
Because the stability analysis of finite populations is intricate, we investigate stability results in the approximation of infinite populations. ...
PRELIMINARIES We present a brief overview of pulse-coupled oscillators and the phase density model obtained in the case of infinite populations.

We present the stability diagram and calculate several of its bifurcation curves analytically, for both excitatory and inhibitory coupling. ...
Using the Ott-Antonsen ansatz, we reduce the behavior of the population to a two-dimensional dynamical system with three parameters. ...
When K = 0, however, the excitable elements feel the pulses of the self-oscillators, and the collective dynamics are no longer as clear. ...

We show that in the limit cycle mode, high-frequency stimulation of an inhibitory population can stabilize an unstable resting state and effectively suppress collective oscillations. ...
Collective oscillations and their suppression by external stimulation are analyzed in a large-scale neural network consisting of two interacting populations of excitatory and inhibitory quadratic integrate-and-fire ...
For simplicity, we do not consider recurrent excitation within the E population, since it is not essential for the emergence of collective oscillations. ...
