Abstract:The effect of noise on a two-dimensional neural map with stable subthreshold oscillations is investigated by numerical simulation. It is found that noise can induce action potential and stochastic resonance. Furthermore, the influences of control parameter and input signal frequency on the dynamics of the system are also studied. Only when the parameters are chosen in or near to the regime of silence, we can observe the frequency-dependent stochastic resonance phenomenon.
Keywords:two-dimensional neural map  subthreshold oscillations  Gaussian white noise  stochastic resonance
