Using harmonic noise,the frequency effect of noise on the FitzHugh-Nagumo neuron model is investigated.The results show that the neuron has a resonance characteristic and responds strongly to the noise with a certain frequency at fixed power.Driven by the noise with this frequency,the train is most regular and the coefficient of variation R has a minimum.The imperfect synchronization takes place,which,however,is optimal only for noise with an appropriate frequency.It is shown that there exists coherence resonance related to frequency.
