| Abstract(in English) | Hippocampus is assumed to play a significant role in memory process.Especially,the hippocampal LTP is assumed to join in a function of memories′ formation.On the other hand,memorized inform ation by the LTP must be read out or depressed by some mechanism. Then we suppose the hippocampus to have to states itself.One is the state in which the LTP is easy to occur and another is not for read out.We study a change of the hippocampal fast ryhthm,as an expression of the states. In this research,we assume that hippocampal inhibitory interneurons control frequency and power of the fast rhythm and propose its model.It is shown that the power of the fast rhythm becomes large when the output level of inhibitory interneurons is small.When the power of the fast rhythm is small,the LTP is easy to occur.From the result,we estimate that the shortness of the inhibitory signal makes the hippocampal state to be easy to cause the LTP.The model is extended further to include the septal inhibitory neurons that send signal to the hippocampal inhibitory interneurons. |
