Abstract
Three induces are discussed to study the new dynamics properties both analytically and numerically for noise-induced Fitzhugh-Nagumo system; the three induces are as follows: Lyapunov exponent, the density distribution of trajectories and power spectrum; the numerical experiment indicated that the noise can induce the system to quite regular dynamics, including coherence resonance (in the case of uncoupling) and stochastic synchronization (in the case of coupling), noise can control the dynamics properties and some other new phenomena that the synchronization takes place only for some moderate noise intensity is also found for the first time.
