Free choice learning and relearning in HPC-lesioned animals. IA mice and Veh controls underwent free choice learning in the 1st week and free choice learning in the 2nd week (F-F_r). (A,D) IA mice could not acquire the free choice task in the 2nd week as shown by low accuracy values [Treatment: F_{(1, 21)} = 20.02, p < 0.001] and low numbers of accurate learners (5/13). (B,C) In the 2nd week IA mice displayed longer latencies and more wrong platform visits [Treatment: F_{(1, 21)} ≥ 7.88, p ≤ 0.011]. Again there was a parallel decrease observed in both parameters indicating the acquisition of an alternative response.
