Abstract(in English) In the hippocampal Ca1 area, the LTP and LTD were induced by the several stimuli pattern. It is shown that LTP and LTD are triggered by an increase in the level of postsynaptic intracellular calcium concentration. We reported that LTP and LTD were induced by temporal pattern stimuli in the hippocampal CA1 area. In this sutdy, the spatial distribution of LTP and LTD induced by tempral pattern stimuli was investigated using the calcium imaging method ni the hippocampal CA1 area. We found that LTP was induced by calcium concentration with high magnitude. On the other hand, LTD was induced by low concentration. After the LTP and LTD induced stimuli, the calcium concentration maintained slightly higher level than before those stimuli. It is suggest that this phenomenon may be related to inducing LTP and LTD.
