The intervention follows the identical clinical procedure used for adults. Initially, the resting motor threshold will be determined by stimulation over the motor cortex, by finding the minimal intensity that produces a motor response in the corresponding distal wrist muscles. The rTMS will be delivered with a powerMAG research ppTMS stimulator (Mag \& More), and a figure-of -eight coil, PMD70-pCool (Mag \& More). The intervention is within the intended use of this CE-marked medical device. The research participants will receive 1Hz rTMS with daily sessions on 20-30 consecutive week days. The magnetic pulses will be applied at 120% of the resting motor threshold with a figure-of-eight coil at a 45 degree angle towards the midline. The 1Hz rTMS protocol is applied 6 trains of 1-min duration separated by 30-sec inter-train "off" periods over the right DLPFC (F4 site 5 according to the10-20 system). The total duration of one 1 Hz rTMS session is 8 min 30 s.
