| Abstract(in English) | We report that the inhibitory synaptic input can control the transmission of synfire chain. Synfire chain is a phenomenon in which synchronous firings transmit between groups of neurons. Many previous studies discussed synfire chain as a fixed cable, and no studies investigated to control synfire chain flexibly. In this study, we numerically analyze the Hodgkin-Huxley model in order to examine whether the synfire chain can be controlled by topdown signals. As a result of simulation, inhibitory synaptic input 6ms before the pulse packet input with short duration strongly facilitated the transmission of synfire chain. Moreover, that 1ms after the pulse packet input strongly depressed the transmission of synfire chain. In Conclusion, synfire chain could be controlled by a inhibitory synaptic input, and could performed dynamically and functionally. |
