Slow-fast dynamics and periodic behaviour in mean-field systems

We will study a model of noisy units in mean field interaction, which is described in the large population limit by a non linear PDE. Relying on a slow/fast approach we will show the emergence of noise induced periodic behaviors. We will focus in particular on the case when each unit evolves according to the FiztHugh Nagumo model.
