| Abstract(in English) | The hippocampus is considered that it keeps short-term memories and participates in the fixation of long-term memory. Recently it is reported that a neurogenesis occurs in the dentate gyrus in the hippocampus of adult mammalians. In this report, we modify a firing-rate coding type hippocampal model proposed by Weisz and Becker. We use a Izhikevich type spiking neuron as a constituent neuron in the network model. Additionally, we introduce Spike-Timing Dependent synaptic Plasticity (STDP) rule. Then we apply a morphogenesis model by Butz to the neurogenesis network reproducing neurogenesis caused by theta-burst reported by Tozuka. As a result, the numerical experiments show that proposed model maintains basal memories before neurogenesis, and it can store novel memories. |
