Summary:
In this study, we consider a system of coupled two fast-spiking neurons as a motif of an interneuron network. We investigate the bifurcation structure to clarify synchronization phenomenon of the neurons. As a result, we find that unidirectionally coupled neurons with an excitatory or inhibitory synapse, easily achieve synchronization at a higher or lower firing frequency than the fundamental frequency of a post-synaptic neuron. When an electrical synapse is added to above model, the neurons have a wider parameter region in which stable synchronous firing is observed than unidirectionally coupled neurons have. Furthermore, we can observe the coexistence of two synchronized states.
