We consider a discrete version of the famous PDE, the FitzHugh-Nagumo equation. The local map, f(u, v) = (u + A h(u) - \alphav, v + \betau - \chiv) with A, \alpha, \beta, and \chi real parameters, plays an important role in the study of the space of traveling waves solutions of the coupled map lattice. We prove that the map f is a Morse-Smale diffeomorphism in some range of parameters and has two horseshoes in other range of parameters.
