Number of trials required on a motor response learning task on a T-maze to reach criterion (90% correct responses over 10 trials) on the first day of acquisition training and on the reversal training on the final day of testing. Saline-pretreated rats (SALINE) received 4 injections of saline (1 mL) and methamphetamine (METH)-pretreated rats received 4 injections of METH (10 mg/kg, s.c.) at 2-hr intervals six weeks prior to the start of the motor response training. Data are mean ± SEM, n=7 / group.
