Abstract Acutely, 3,4,‐methylenedioxymethamphetamine (MDMA) induces cerebrovascular dysfunction [ Quate et al ., (2004) Psychopharmacol. , 173 , 287–295]. In the longer term the same single dose results in depletion of 5‐hydroxytrptamine (5‐HT) nerve terminals. In this study we examined the cerebrovascular consequences of this persistent neurodegeneration, and the acute effects of subsequent...
MDMA causes selective depletion of serotonergic terminals in experimental animals and the consequent decrease in synaptic 5-HT may, inter alia, increase impulsivity. To study the effects of MDMA upon brain function, the behaviour of male Dark Agouti rats exposed to MDMA (15 mg/kg i.p.), two 5-HT1B agonists (CGS-12066A and CP-94,253, both 5 mg/kg i.p.) or saline were investigated in the...
