Place-field rates changed on familiar trajectories after the switch. A, Rate maps of four example place cells (a–d), each from a different session, during consecutive blocks of three laps on one of the two familiar trajectories (LR, RL). Only the central track and its surrounding segments are shown. Each row represents a cell. Color codes firing rate with the number showing peak rate in hertz. Notice the different color scales for LR and RL. E and T are the central track entrance and exit, respectively. Black dashed line, Switching laps. Red dashed lines, Actual first laps on new trajectories. B, Average normalized rate changes (mean ± SE) on the central track across all the place cells during the baseline laps before the switching (baseline), during the laps on familiar trajectories after the switching laps but before the actual first laps on new trajectories (pre), and during the laps on familiar trajectories after the actual first laps on new trajectories (post).
