Methamphetamine (A) and AMPH (B) concentrations in the striatum 0 min (n = 6) prior to or 30 min (n = 5/group), 60 min (n = 5/group) or 90 min (n = 5/group) after the challenge injection of METH (0.4 mg/kg). Rats were pretreated with either saline (SAL) or METH (4.0 mg/kg) 3.5 h prior to administration of the challenge injection. * = p < 0.05 significantly different than SAL-METH.
