Figure 2.

During rotation, place cell discharge in the rats trained only to forage for scattered food was different than the discharge from cells in rats trained to navigate. Firing rate patterns during rotation were judged to be similar to the stable pattern if r_sim > 0.19. If r_sim ≤ 0.19, they were judged to be disrupted. Firing rate patterns were classified as either preserved in the stationary, rotating, or both reference frames. The majority of firing rate patterns was disrupted in the forager group (A), whereas the majority was preserved in the navigator group (B). The place cells in the navigator group were more likely to be preserved in the stationary frame that defined the goal.
