the lesion. We found that, in rats with ACC lesions, movements in the direction that was contralateral to the lesion took significantly longer to redirect on STOP-change trials (t(718) = 2.8404; P = 0.0046), but no differences were observed when the correct response was being made in the direction that was ipsilateral to the lesion (t(718) = 1.4737; P = 0.1410). Collectively, these findings suggest that ACC contributes to both the inhibition and the redirection of behavior for STOP-change trials in both response directions.
