Reversal impairments caused by OFC lesions are abolished by lesions of ABL. Bars show the average number of trials (+SEM) required to retain and reverse a 2-odor discrimination problem for controls, rats with OFC lesions, rats with OFC lesions combined with bilateral ABL lesions, or rats with ABL lesions alone. As expected, OFC lesions impaired reversal learning. This impairment was abolished by pre-training lesions of ABL. ABL lesions alone had no effect. *, p < 0.05.
