Coherence resonance in models of an excitable neuron with both fast and slow dynamics
Robert C. Hilborn, Rebecca J. Erwin
Abstract
We demonstrate the existence of noise-induced periodicity (coherence resonance) in both a discrete-time model and a continuous-time model of an excitable neuron. In particular, we show that the effects of noise added to the fast and slow dynamics of the models are dramatically different. A Fokker-Planck analysis gives a quantitative explanation of the effects.
