The purpose of the project is to assess the efficacy of parietal transcranial magnetic stimulation in misophonia. N=60 participants will undergo two transcranial magnetic stimulation sessions: one inhibitory and another excitatory. During both sessions, the parietal region will be stimulated. Participants will perform computerized tasks immediately before and after the stimulation, while EEG, heart rate, and skin temperature will be recorded. These recordings will be used to assess if TMS can be used to improve tolerance to misophonia triggers.

Transcranial Magnetic Stimulation (TMS) is an FDA-approved non-invasive brain stimulation technology. It is currently used for treating depression. Applications to other disorders such as OCD and anxiety using TMS are currently under investigation. TMS will be administered for 25 minutes.

RECRUITINGUnpleasantness Rating Scale
Participants will be presented with a slider with extremes labelled as extremely unpleasant and extremely pleasant. Ratings will be provided for audio clips and visual cues. Full scale from 0-100, higher score indicates more unpleasantness
Time frame: after each session, 72 hours apart (each session is 2 hours)
Heart Rate
The heart rate (number of beats per minute) will be measured using a wristwatch worn by the participant.
Time frame: after each session, 72 hours apart (each session is 2 hours)
Skin Conductance Response
Skin conductance, a measure capturing the amount of sweat, will be measured using a wristwatch worn by the participant.
Time frame: after each session, 72 hours apart (each session is 2 hours)
EEG P1-N1-P2 Complex Peak Amplitude
Amplitude (microvolts) of P1, N1, and P2 peaks measured in the parietal region
Time frame: after each session, 72 hours apart (each session is 2 hours)
EEG P1-N1-P2 Complex Peak Latency
Latency (milliseconds) of P1, N1, and P2 peaks measured in the parietal region
Time frame: after each session, 72 hours apart (each session is 2 hours)
EEG Frequency Band Amplitude
Amplitude (decibel) in theta (4-8 Hz), alpha (8-13 Hz), and beta (13-30 Hz) frequency bands in the parietal region
Time frame: after each session, 72 hours apart (each session is 2 hours)
