(A) Proportions of maladaptive behavior in RGT are represented for each group. Maladaptive behavior consists in poor decision-making (preference for disadvantageous options), undecided behavior (no preference for any option), and inflexible behavior (marked preference related to a spatial preference developed during training). Mean time-course of choices (mean ± SEM) of each group displaying inflexible (B), undecided behavior (C) as well as poor decision-makers (AC and OF lesioned rats pooled) (D). Gray line represents no preference level, 50%. Comparison of scores of inflexible lesioned rats with no preference level (gray line) t-test; ***p < 0.001.
