| Outline of Final Research Achievements |
In our study, interaction of the spatiotemporal learning rule (non-Hebbian, bottom-up, i.e. "local") and the Hebbian learning (Top-down, i.e. "global") are experimentally and theoretically investigated in hippocampal system. To clarify the detail properties of the information of spatiotemporal sequence affects the postsynaptic membrane potentials of single pyramidal cells in the hippocampus, the stimuli of the spatio-temporal pattern were applied using high-speed uncaging system. Our results show non-linear property of Cantor coding in steady and non-steady states, and discussed in relation to theoretical model for learning and memory.
