Left temporal verum cTBS
EXPERIMENTALContinuous theta burst stimulation (MC-B70, MagPro,MagOption, Medtronic, Germany): 400 triplets of stimuli (triplets with 50Hz) at an frequency of 5Hz (in sum 1200 stimuli) with a break after 200 bursts over the left Heschl's gyrus targeted with anatomical neuronavigation (Localite, Germany); 30% maximum stimulator output (each session) Intervention: Left temporal verum cTBS
Left temporal placebo cTBS
