| Abstract(in English) | In this paper, by using a hippocampal model it is elucidated that theta phase precession contributes to memory encoding of the spatio-temporal sequence in the sense that not only temporal order but also the spatial content of experience can be stored and retrieved in a considerable accuracy. Furthermore, learning is found to markedly depend on the velocity of animal during traversal. From this interesting finding, a theoretical prediction about firing rate of hippocampal neurons and animal's velocity is given, which is successfully consistent with existing experimental evidences. These results suggest that the hippocampus with dynamics of theta phase precession is able to store spatio-temporal sequence that is necessary for the storage of episodic memory. |
