Study Arms (1)

Left dorsolateral prefrontal cortex (DLPFC) Butterfly Coil

EXPERIMENTAL

High frequency rTMS ( Alpine Biomed Mag Pro Option): 2000 stimuli of 20 Hz over the left DLPFC (each session), Butterfly-water-cooled-Coil, 110% motor threshold; followed by: low frequency rTMS ( Alpine Biomed Mag Pro Option) applied over left temporoparietal cortex, Butterfly-water-cooled-Coil (2000 Stimuli of 1 Hz each session), 110% motor threshold. Relaxation therapy during the 1Hz stimulation with external audio tape instructions.

Device: Left DLPFC Butterfly Coil
