Стохастические осцилляции в двумерном дискретном отображении нейрона

Abstract

We study the two-dimensional Rulkov model with discontinuous function under the influence of random disturbances. We considered a zone where periodic oscillations are observed. The impact of random disturbances on the system leads to a change in the regime of neural activity. Using direct numerical simulation, the stochastic sensitivity function technique and the method of confidence domains, we describe this phenomenon.
