Interventions

  • Transcranial Magnetic Stimulation — DEVICE
    Transcranial Magnetic Stimulation (TMS) is a non-invasive form of brain stimulation. TMS can influence activity in various brain regions, and it allows researchers to test or modify brain circuit communication. The MagPro X100\* magnetic stimulator and Cool-B65 Butterfly Coil are FDA-approved for rTMS treatments of depression.

Study Details

The research study is being conducted to study brain patterns of negative emotion and develop personalized brain stimulation protocols to disrupt these patterns with transcranial magnetic stimulation (TMS). First, the investigators will use functional Magnetic Resonance Imaging (fMRI) data to generate a negative affect map for each participant. Then, the investigators will apply a variety of repetitive transcranial magnetic stimulation (rTMS) sequences while the participant is inside the MRI scanner to determine the optimal and least optimal rTMS frequencies at changing negative affect brain states. Finally, these two frequencies will be tested over two 3-day rTMS neuromodulation sessions to assess whether they can reduce negative emotions.

Arms

  • Experimental: Neuromodulation using the optimal rTMS stimulation frequency
    Through manipulation of brain state with a negative-affect task and using fMRI as the feedback signal, the investigators aim to fine-tune repetitive Transcranial Magnetic Stimulation (rTMS) delivery to maximally impact the desired brain states in awake, behaving participants in a highly individualized manner (Visit 3). The optimal rTMS stimulation frequency will then be tested in a 3-day rTMS neuromodulation intervention.
  • Active Comparator: Neuromodulation using the least optimal rTMS stimulation frequency
    The investigators will compare the results of the optimal rTMS frequency neuromodulation with a separate 3-day neuromodulation session using the least optimal rTMS frequency, as determined by the results of Visit 3.

Primary Outcome Measure

Change in ruminative response scale (RRS) score after using the optimal rTMS stimulation frequency vs the least optimal rTMS stimulation frequency [ Time Frame: Up to 4 weeks ]
