What this Trial Is About
Investigators are conducting this study to test if temporarily and non-invasively stimulating the brain will affect the emotional response to stress in healthy participants. Participants will perform a series of tasks while completing an MRI scan. After this, participants will be randomized to undergo transcranial magnetic stimulation (TMS) at two visits, undergoing active stimulation at one visit and undergoing 'sham' stimulation at another visit. Immediately following both stimulation sessions, participants will repeat the tasks during MRI scanning.
