(A) Diagrams of coronal sections (in reference to bregma) of the cerebellum representing the extent of cell loss observed after bilateral electrolytic lesions of the interpositus nuclei and overlying fibers. (B) Performance during task acquisition (step 1) and during generalization (steps 2 and 3) of the egocentric-based task for Sham-operated rats (black squares) and IN-lesioned rats (clear triangles). (C) Response latencies of Sham and IN-lesioned rats during the different steps of the task. (C1) First criterion day; (C2) second criterion day; (C-1) 1 d before C1; (C-2) 2 d before C1. (*) P< 0.05. Data are expressed as means ± S.E.M. Note that there was no difference in learning the initial task (step 1), whereas IN-lesioned animals showed difficulties transferring the response rule when the starting point was changed (steps 2 and 3).
