Open-field experiment. (A) Typical representations of exploratory patterns of BALB/cJ mice in open field. While the vehicle remains most of the time at the start position, the methylphenidate (MPH)-treated animals explore the whole field, and (B) MPH increased the number of center visits and (C) the distance traveled as well as (D) the velocity. Abbreviations: VEH, vehicle; MPH3, 3 mg/kg i.p. methylphenidate; MPH10, 10 mg/kg i.p. methylphenidate. N = 12 per group, *p < 0.05, ***p < 0.001.
