| Abstract(in English) | We elucidate the role of A-channels and Na channels in backpropagation and synaptic information transmission in the dendrites. We show that A-channels play an important role in the neural interaction, but Na channels do not contribute to neural interaction. In the dendrite, A-channel blockade largely changes inhibition of EPSPs immediately after backpropagations and phase response cureves (which represent effective neural interaction) from these of control cases. If A-channels are not blocked and Na-channel are blocked, these properties are not changed, compared to control cases. In this case, dendritic backpropagations are only reduced. It has been reported that Na channels strongly inhibit EPSPs immediately after the action poteitial backpropagation. Results obtained here imply that active dendritic backpropagation does not affect the neural interaction due to A-channels highly distributed at the dendrite. |
