Theta-Burst Stimulation to Treat Depression

"Intermittent Theta-Burst Stimulation (iTBS) is a form of non-invasive brain stimulation that uses magnetic pulses applied to the scalp using a coil. iTBS will be used to stimulate the left dorsolateral prefrontal cortex (DLPFC) to enhance long-term potentiation (LTP)-like activity, a physiological mechanism associated with brain plasticity. TMS-EEG will be performed to measure changes in brain plasticity throughout the trial. An EEG cap will be placed on the participant's head, and the electrodes on the cap will be filled with saline gel using a dull syringe.~During the intervention, the study team will conduct a baseline TMS-EEG measurement consisting of single TMS pulses. Participants will then complete iTBS-s (experimental study intervention), which will be delivered to the left DLPFC. Following iTBS-s, post-iTBS TMS-EEG measurements will be obtained consisting of 3 TMS trains delivered to the left DLPFC (Post-0, Post-20, and Post-60 minutes)."

Following iTBS-c, post-iTBS TMS-EEG measurements will be obtained consisting of 3 TMS trains delivered to the left DLPFC (Post-0, Post-20, and Post-60 minutes)."
