2A) Rats pretreated with saline (SAL), METH (2 mg/kg) or MEPH (15 mg/kg) were challenged with METH (2 mg/kg). 2B) Rats pretreated with saline or METH (0.5, 2 mg/kg) were challenged with MEPH (15 mg/kg). Temporal data are expressed as activity counts + S.E.M. following METH (2A) or MEPH (2B) injection (arrow). Cumulative data (box) are expressed as total activity counts following METH (0–90 min) or MEPH (0–90) injection. N=8 rats/group. ***p < 0.001, **p < 0.01 or *p < 0.05 compared to SAL/METH; +++p < 0.001 compared to METH/METH.
