Noise Induced Complexity: From Subthreshold Oscillations to Spiking in Coupled Excitable Systems

M. Zaks, X. Sailer, L. Schimansky-Geier +1

We study stochastic dynamics of an ensemble of N globally coupled excitable elements. Each element is modeled by a FitzHugh-Nagumo oscillator and is disturbed by independent Gaussi…
