Entorhinal Cortex Acts Independently of the Hippocampus in Remembering Movement (image) Institute of Science and Technology Austria Share Print E-Mail Caption Rats roam around an arena (A) before tackling a maze memory task. A reward awaits them in the T-maze placed in the arena (B). While it sleeps, the rat consolidates the memory of where the reward was located (C). A place cell emits an action potential every time the rat is in one particular location in the arena (D). A dot is placed at each point a grid cell emits an action potential. The firing location of grid cells (see dots) form a grid over the arena (E). While the rat is asleep, grid cells replay this firing pattern (C).
