The key objectives of this study are to examine whether the specific iTBS protocol at RDLPFC can effectively modulate two subtypes of impulsivity (delayed discounting and reflection impulsivity) and empathy, and to examine whether the participant's baseline self-reported impulsivity and empathy scores mediate the modulatory effects of the iTBS on impulsivity and empathy respectively in normal healthy young adults. The secondary objectives of this study are to examine whether the self-reported measures of impulsivity and empathy correlate with their performance-based counterparts.
