Place cell sequences experienced during behavior (middle panel) are replayed in both forward (left panel) and reverse (right panel) direction during awake SPW-R. The rat is moving from left to right on a familiar track. Spike trains for place fields of 13 CA3 pyramidal cells (color ticks, spikes of individual neurons) on the track are shown before (forward replay; left red box), during (middle), and after (reverse replay; right blue box) a single traversal. The CA1 local field potential is shown on top (black traces) and the animal’s velocity is shown below. Reproduced from [137]
