Amphetamine-Induced Locomotor Activity. For rats previously deprived of food and water (a; Experiment-1) and rats fed ad lib (b; Experiment-2), locomotor activity was not significantly different between adolescent and adult rats after a saline or amphetamine injection. Amphetamine non-significantly reduced amphetamine-induced locomotion. The values are the means±SEM. AMPH, amphetamine. In panel a: adolescents, n=8; adults, n=8. In panel b: adolescents, n=12; adults, n=12.
