简要总结
In this project, we will examine effects of MA on reward function using electroencephalograms (EEG), which will complement our ongoing study with MA and fMRI. We will determine how MA alters reward-related neural activity and how this is related to its subjective rewarding effects. The effects of MA on reward function will be examined using both reward-task-related activation and resting state activity. We will examine the effects of MA on ratings of drug liking and euphoria, as well as on EEG measures sensitivity to reward. Healthy young adults will undergo three EEG sessions with placebo and MA (10 and 20 mg), while performing the Monetary Incentive Delay task and the Stop Task, as a measure of inhibition. We will examine correlations between the neural responses and subjective responses to MA.
Our central hypotheses are 1) that MA will increase feelings of alertness and well-being, and 2) that MA will increase neural responses to anticipation and receipt of reward, and 3) that the effects of MA on mood will be correlated with its effects on neural responses to reward.

结局指标
主要结局
Change in SUbjective Effects as Assessed by Score on "Feel Drug", "Feel High", "Like Drug", and "Want More" Sub-scales of Drug Effects Questionnaire (DEQ).
时间窗: Time Frame: Day 1(baseline), 3
Participants will complete The Drug Effects Questionnaire during the initial baseline session to determine their subjective stimulant profile. The Dug Effects Questionnaire (DEQ) is a visual analog scale questionnaire that assesses the extent to which subjects experience four subjective states: "Feel Drug", "Feel High", "Like Drug", and "Want More". All sub-scales are scored on a visual analogue scale (Scroll bar on computer screen) ranging from 0-100. 100 represents the highest score for that subjective state, and the higher the score, the worse the outcome.
