Summary

This small early study tests whether a gentle brain stimulation technique called temporal interference (TI) can safely reduce PTSD symptoms in 5 adults. Participants will receive TI stimulation and have their brain activity measured with MRI, MEG, and EEG. The goal is to see if symptoms improve and how the brain responds.
