Synchronous firing in a population of inhibitory interneurons coupled by electrical and chemical synapses

The synchronization phenomena occurring in a population of Fast Spiking interneurons, coupled by electrical and inhibitory synapses, are investigated. It is shown numerically that there are regions of the coupling parameters space where synchronous regimes occur. The corresponding theoretical results agree with the numerical ones. It is shown that the presence of the electrical coupling in a heterogeneous population of inhibitory FS cells promote their synchronous discharge.
