From: Role of adult neurogenesis in hippocampal-cortical memory consolidation
How does adult neurogenesis accelerate the systems consolidation? Adult hippocampal neurogenesis in the DG may help to generate the SPWs in CA3. The SPWs could provide the activation required to drive inter-cortical plasticity through the reactivations of CA1 pyramidal cells, and therefore promote cortical consolidation during subsequent periods of inactivity and sleep. Simultaneously adult neurogenesis erases the pre-exciting memory in the DG.
