Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Open label
Open label study. Participants will be screened by study staff for contraindications to TMS treatment. TMS will be delivered use the MagVenture TMS machine.
Transcranial magnetic stimulation
Resting motor threshold will be established by first finding the area of the motor cortex associated with visible twitch of the right abductor pollicis brevis (APB). Parameter Estimation by Sequential Testing (PEST) will be conducted to quantify resting motor threshold using visible APB twitch. The left dorsolateral prefrontal cortex (DLPFC) will be located using the Beam F3 method and marked with a felt-tipped marker on the scalp. TMS will be delivered over left DLPFC at 110% of resting motor threshold at 10Hz (5-seconds-on; 10-seconds-off) for 15 minutes per session (3000 pulses), 3 sessions each day (30-minute rest in-between sessions), for 3 days (within 5 consecutive days; a total of 27,000 pulses).
