Abstract
We propose a method to analytically show the possibility for the appea rance of a maximum in the signal-to-noise ratio in nonpotential system s. We apply our results to the FitzHugh-Nagumo model under a periodic external forcing, showing that the model exhibits stochastic resonance . The procedure that we follow is based on the reduction to a one-dime nsional dynamics in the adiabatic limit and in the topology of the pha se space of the systems understudy. Its application to other nonpotent ial systems is also discussed.
