Fig. 1

1A) Rats pretreated with saline (SAL), cocaine (COC) (15 mg/kg) or MEPH (15 mg/kg) were challenged with COC (15 mg/kg). 1B) Rats pretreated with saline or COC (15 mg/kg) were challenged with MEPH (15 mg/kg). Temporal data are expressed as activity counts + S.E.M. following COC (1A) or MEPH (1B) injection (arrow). Cumulative data (box) are expressed as total activity counts following COC (0–30 min) or MEPH (0–90) injection. N=8 rats/group. ***p < 0.001, **p < 0.01 or *p < 0.05 compared to SAL/COC; +p < 0.05 compared to COC/COC.
