Abstract
We study the dynamics of a lattice of coupled nonidentical Fitz Hugh-Nagumo system subject to independent external noise. It is shown that these stoch astic oscillators can lead to global synchronization behavior without an ex ternal signal. With the increase of the noise intensity, the system exhibit s coherence resonance behavior. Coupling can enhance greatly the noise-indu ced coherence in the system.
