Figure 2.

Horizontal locomotor activity after a single administration of saline (A and B) or 10 mg/kg METH (C and D) in mice pretreated with aripiprazole (1 or 10 mg/kg) or vehicle. Values are shown as the mean ± SEM (n = 6–7). There was the discrepancy in sample sizes between Figure 1 and Figure 2 because of the loss of the locomotion data due to computer problems. *P < 0.05, compared with vehicle-pretreated mice (post hoc Bonferroni/Dunn test).
