 The area stimulated will be the left dorsolateral prefrontal cortex DLPFC. Before applying rTMS over the DLPFC will be necessary to map the area of the representation of the FID by applying single pulses to measure the motor evoked potential MEP and resting motor threshold RMT. The intensity adopted in real rTMS session will be 80 of the RMT. rTMS will be applied in just one session divided in to 5 blocks of stimulation. Each block will be separated by 5 minutes intervals. In each block 15 rTMS series of 1-second duration at 10 Hz frequency were applied. The interval between sets will be 10 seconds. The sham stimulation will be applied with the same settings real rTMS, but the coil will be not coupled to the magnetic stimulator, so the individual will be not able to differentiate the real session of sham.
