| Abstract(in English) | It is known that the synchronous firings of the neurons relate to infomation coding in the brain. In this study, we research synchronization in the coupled two fast-spiking neurons based on a sub-network in the neocortical interneuron network. We consider two coupling types; 1) a chemical synapase, and 2) a gap junction. As a result, in case (1), we show that the neurons are synchronized at a higher or lower firing frequency than the firing frequency of the post-synaptic neuron for the excitatory or inhibitory coupling, respectively. On the other hands, in case (2), we find that the firing period of coupled neurons is faster than the average of a unique period of the neurons at the same value of external DC current. Futhermore, in both cases we observe the Arnold's tongue sturucture formed by saddle-node or period doubling bifurcation. |
