Effects of intermittent ethanol and MDMA administration during adolescence on the acquisition criterion score in the Hebb-Williams maze. The mazes were classified as easy (1, 3 and 4) or difficult (5 and 8). Mice were treated with Saline (Sal), 10 or 20 mg/kg of MDMA (M10 and M20), 1.25 g/kg of ethanol (E1.25), or 1.25 g/kg of ethanol + 10 or 20 mg/kg of MDMA (E1.25 + M10 and E1.25 + M20). The acquisition criterion score is considered to be the completion of the task in less than 60 s in two consecutive sessions. Data are presented as mean values ± S.E.M. Differences with respect to the non-ethanol-treated groups ** p < 0.01.
