Abstract(in English) In the hippocampal CA1 area, repetitive correlated spiking of pre- and postsynaptic neurons can induce LTP and LTD, depending on the timing of the pre- and postsynaptic excitation (Spike timing Dependent Plasticity). While, it is shown that LTP and LTD are triggered depending on the level of postsynaptic intracellular calcium concentration. In this study , Ca^<2+> influx induced by the protocol of timing between pre- and postsynaptic excitation were spatially investigated by using the calcium imaging method in the hippocampal CA1 area. We found that the magnitude of LTP and LTD closely related to the velocity of calcium influx during repetitive stimulus.
