Psychobiologic studies including: assessment of possible neurophysiological, psychological and cognitive alterations in chronic MDMA users; evaluation of the role of serotonin, dopamine and norepinephrine systems in mediating the effect of MDMA on mood, psychomotor behavior and sensorimotor gating in humans, investigating whether regular MDMA users show alterations in 5-HT reuptake site densities indicative of neurotoxic effects after long-term MDMA use. MAPS donated $6,000 to a sub-study in which 10 MDMA-naive subjects will receive a PET scan to measure serotonin reuptake sites before and after a single dose of MDMA (1.5-1.7mg/kg)
