Basal and cocaine-stimulated locomotor activity after microinjection of the 5-HT2AR antagonist M100907 into the VTA. A, Mean (±SEM) total horizontal activity (counts per 60 min) after intra-VTA microinjection of saline (Sal) or M100907 (M100) (0.1 or 0.3 μg/side) followed by intraperitoneal injection of saline or cocaine (Coc) (10 mg/kg). *p < 0.05 versus Sal + Sal; ∧p < 0.05 versus Sal + Coc (Student–Newman–Keuls test). The time course of horizontal activity plotted in 15 min bins across the 60 min test session is depicted for basal (B) and Coc-stimulated (C) activity.
