Top panels: Mean plasma OT concentrations scores following administration of MDMA, IN-OT, or placebo as a function of dose and time. Bottom panels: Individual plasma OT concentrations scores following administration of placebo, MDMA (1.5 mg/kg: left panel), or IN-OT (20 IU and 40 IU: center and right panels) as a function of time. The closed arrow denotes time of capsule administration. The open arrow denotes time of nasal spray administration. An * indicates 1.5 mg/kg MDMA significantly different from placebo (p<0.05). A + indicates 1.5 mg/kg MDMA significantly different from 0.75 mg/kg MDMA (p<0.05). Error bars represent one SEM.
