(A, B) Time-course of locomotor activity in 20-min blocks across 60-min session following MDMA challenge (2.5 mg/kg), in rats treated 15 or 100 days earlier with saline vehicle or MDMA injections (5.0 mg/kg twice daily for 5 days) in either their home cages (unpaired group) or the activity monitors that were used for subsequent tests of sensitization (paired group). *p < .05 compared with all other treatment groups. (C) Overall locomotor activity in response to MDMA challenge. *p < .05 and **p < .01 compared with all other treatment groups. (D, E) Time-course of stereotypy in 20-min blocks across 60-min session following MDMA challenge. *p < .05 compared with all other treatment groups; #p < .05 compared with saline/unpaired group; †p < .05 compared with both saline groups. (F) Overall stereotypy time in response to MDMA challenge. ##p < .01 compared with MDMA/unpaired; ***p < .001 compared with saline groups. All points represent mean (±SEM).
