The primary aim of this protocol is to determine whether the use of repetitive transcranial magnetic stimulation (rTMS) over vermis of the cerebellum may be safe and therapeutically effective in patients with schizophrenia. Because this is the first evaluation of this treatment in this population, the focus of this study is safety.

Device: MagPro X100 rTMS Machine

Experimental: Safety of rTMS in schizophrenia patients Device: MagPro X100 rTMS Machine

To maximize the efficacy, participants will receive 10 rTMS sessions to the vermis (lobule VII) of cerebellum. These 10 rTMS sessions will be administered from Monday to Friday in five days, twice a day with a minimum of 4-hour gap between the sessions. Repetitive TMS will be applied with a figure of 8, double-cone-shaped coil by positioning the stimulation coil over the appropriate position on the subject's scalp. rTMS, with the intermittent theta burst pattern (iTBS) (20 trains of 10 bursts given with 8-s intervals), will be applied at 80% of active motor threshold. These parameters are known to cause excitation in brain activity. Each participant will receive 600 pulses per session. The size of the brain area that is stimulated is about 2 x 2.5 cm and is expected to reach the vermis area.

Anatomically precise localization of rTMS will be achieved using a frameless stereotactic system.
