| Abstract(in English) | In the hippocampus, the long-term potentiation with asymmetric time window could be contribute to the neural basis of the memory storage of the temporal sequence. However, there is a big gap between the time scales of the synaptic asymmetry (<100ms) and the behavior (fromsec to min). Recently, it is considered that "theta phase precession" contributes to the memory ofthe temporal sequence by means of "emporal compression". It is important to clarify whether theta phase precession enables the memory storage. In this paper, we elucidate the ability of memory storage by using a theoretical model. It is concluded that theta phase precession encodes the memory storage that is impossible by the rate coding with the original time scale. |
