This paper studied the phenomenon of coherence resonance on neurons induced by noise.Based on the two-dimensional map-based neural model,studied the effect of Gaussian white noise on the dynamics of neurons by numerical simulation,where Gaussian white noise was used to imitate the noisy environments of biological neural systems.It was found that adding the noise led to an enhancement of excitability of silent neurons,even induced spikes.When the noise intensity took an appropriate value,the regularity of sp...
