| Outline of Final Research Achievements |
In this research, we have constructed a hippocampal-neocortical model for episodic memories based on physiological, anatomical and neuropsychological findings and examined its characteristics by computer simulation. As the results, we have shown that the proposed model can deal with general temporal sequences owing to the neurogenesis in DG, chaotic neurons in CA3, and the asymmetric spike timing dependent synaptic plasticity introduced to the learning of CA3. Moreover, we have revealed that the chaotic recall in the hippocampal network much contributes to extract stored sequences, reduce catastrophic forgetting in the neocortical network, and the consolidation of the long-term memory.
