WebPlace cells are hippocampal cells that fire specifically when the animal is at a certain location (7). Each place in an environment is defined by a unique combination of active place cells (8, 9). WebAug 13, 2024 · Intriguingly, simultaneously recorded grid cells have been reported to activate in coherence with the replaying place cells (Ólafsdóttir et al., 2016), suggesting that the grid cell population might mirror the replay trajectory by recalling the corresponding spatial locations of the reactivating place cells.
