We report a numerical study of the synchronisation phenomena occurring in a network of identical FitzHugh-Nagumo oscillators, with all-to-all synaptic coupling described by α function. A variety of states with different type of synchronisation (either in amplitude, or in phase or frequency) is found to occur, depending on the number of oscillators and on the coupling parameters. Our results support the view that the behaviour of large ensembles of neurons can be understood by the knowledge of small ones.
