PG - 203-6 AB - 3,4-Methylenedioxymethamphetamine (MDMA), a non-hallucinogenic drug of abuse, potently depressed firing rates of a subpopulation of serotonin neurons in the dorsal and median raphe. High neurotoxic doses depressed those serotonin neurons unresponsive to low doses. Noradrenaline neurons in the locus coeruleus were also depressed by moderate doses. Dopamine neurons were unaffected. It is concluded that MDMA's unique psychological effects are mediated through a subpopulation of serotonergic and noradrenergic neurons, presumably through effects on release mechanisms.
