Many studies have focused on the acute effects of MDMA on memory. In the present study, we intraperitoneally administered MDMA （0, 5, 10, 20 mg/kg） to adult male rats to investigate the effects of different doses on rat spatial memory in the Morris water maze, body temperature, and mortality, twice a day, for 7 successive days. The results indicated that MDMA impaired spatial memory dose-dependently, with the highest dose （20 mg/kg） exerting the strongest effects. In addition, MDMA also caused hyperthermia and increased mortality in rats展开更多
