Schematic Diagram of Reverse Replay
  

(a) While a rat runs along a linear track, hippocampal neurons are active in a place-specific manner. In this example, the preferred places of five different hippocampal place cells are shown as elipses on the track. As the rat runs through successive locations on the track, place cells associated with these locations become active, as indicated by the red shading.

(b) When a rat stops at the end of a linear track after running down it, the sequence of cell activity experienced during running is replayed in reverse order.
