Effect of repeated aripiprazole (1, 3, or 10 mg/kg) administration on the following: (A) latency to start locomotion, (B) number of crossings performed and (C) number of rearings performed during a 5-min exploration period of an open field. Animals received an ip injection of saline, Tween, or aripiprazole for 5 d (subchronic treatment). Behavioral parameters were recorded 30 min after the last administration. Data are expressed as the mean±SEM. n=8–10 animals per group. bP<0.05 compared to the saline group; ANOVA/Duncan's test.
