Abstract:Reactivation of place cells during sharp-wave ripples (SWRs) in the hippocampus is pivotal for memory consolidation, yet the SWR dynamics between the hippocampus and its neighboring subiculum remain underexplored. This study examined the differential SWR-associated reactivations of task-demand-associated representations in the subiculum and CA1 during a visual scene memory task in rats. In the task, the spiking activities of place-cell ensembles were reactivated during a SWR event according to task demands. Th… Show more
