Phase 2, the patients will receive one of two treatments: High-frequency (10Hz, 100 trains of 1.9 sec with 15 sec inter train interval) dTMS targeting the ACC or sham stimulation for 30 min. Each treatment will be precede by a short guided imagery (1-2 min) design to activate the relevant brain circuitry (provocation of symptoms may increase response rate to Deep TMS as was evident in the treatment of PTSD, cigarette smoking and OCD). dTMS sessions will be conducted five times per week for 3 weeks, for a total of 15 sessions. A second rsfMRI scan will be obtained at the end of this phase.
