Titre : On a Feedforward Chain of Periodically Kicked FitzHugh-Nagumo Neurons

Résumé : In this talk I will discuss a recent model unidirectionally coupled chain of FHN equations. At one end of the chain, the neuron receives kicks which are propagated along the chain. Existence of periodic solutions result from a fixed point argument for both $\epsilon$ zero or small. Varying the period of kicks lead to mixed mode oscillations. Numerical simulations illustrate that this behavior relates on concurrence between speed along fast fibers and speed along slow manifolds for close trajectories.
