Fig. 8: Locations represented at the end of replay sequences plotted against animals’ actual stop locations.
From: Hippocampal place cell sequences differ during correct and error trials in a spatial memory task
The y-axis shows the location represented at the end of each replay sequence detected during rest periods of all trials (correct trials correspond to stop location 0 and error trials correspond to other stop locations). The x-axis shows rats’ actual stop locations for all trials. Actual stop locations ranging from −3 to −1 indicate that rats stopped at incorrect locations that were 3 to 1 locations before the correct location (i.e., undershoot error trials). Actual locations ranging from 1 to 3 indicate stop locations that were 1 to 3 locations after the correct reward location (i.e., overshoot error trials). Actual locations equal to 0 indicate that rats stopped at the correct reward locations (i.e., correct trials). The colorscale shows the trial counts for each x–y pairing. Results from errors in trials 1–4, trials 5–8, and post-test trials are shown in left, middle, and right panels, respectively. Matthews correlation coefficients were close to zero (equal to 0.0715, 0.0390, 0.0160, respectively, for left, middle, and right panels, with corresponding bootstrap estimates of 0.0713 ± 0.0380, 0.0431 ± 0.0271, 0.0197 ± 0.0349).
