Neuromodulation of Brain and Emotional Responses to Psychological Stress
University of Pittsburgh
Summary
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.

1. Medication Use a. The following medications can affect brain and cardiovascular measures being obtained in this study; thus, use of the following medications on one or more occasions in the past 14 days constitutes grounds for exclusion: i. Antihypertensive or cardiac medications (diuretics, beta blockers, calcium channel blockers, ACE inhibitor/ARB, cardiac glycosides, central sympatholytic HTN drugs, anti-arrhythmic drugs, vasodilator drugs, other cardiac drugs) ii. Anticonvulsant medications iii. Anti-Parkinson medications iv. Protease inhibitors or other Anti-HIV medications v. Medi…
Interventions
- DeviceActive continuous theta burst stimulation
This intervention involves an active form of continuous theta burst stimulation (cTBS) that will be targeted to the dorsal anterior cingulate cortex based on neural navigation software. cTBS will be delivered in one session, lasting a few minutes, before participants complete additional testing.
- DeviceSham continuous theta burst stimulation
This intervention involves an sham form of continuous theta burst stimulation (cTBS) that will be targeted to the dorsal anterior cingulate cortex based on neural navigation software. cTBS will be delivered in one session, lasting a few minutes, before participants complete additional testing.
