Cognitive performance in (+/-) 3,4-methylenedioxymethamphetamine (MDMA, "ecstasy") users: a controlled study.

abstract：:Low doses of 8-OH-DPAT (62.5-250 micrograms/kg) were reinforcing in the place preference conditioning procedure, while a higher dose (1 mg/kg) supported a conditioned place aversion. The 5-HT synthesis inhibitor PCPA, and the DA antagonists pimozide and sulpiride, had no effect when administered alone, but abolished t...
