 Since 1990s, stimulation of prefrontal cortex PFC has shown therapeutic effects on auditory hallucinations as well as negative symptoms of schizophrenia. However, previous studies have reported mixed or negative results. Majority of the repetitive transcranial magnetic stimulation rTMS studies to date has set the target of cortical stimulation based on scalp site. Recently introduced method, navigated transcranial magnetic stimulation nTMS integrates the individual MRI data, and thus allows more precise targeting on brain cortical regions enhancing the efficacy of rTMS. Previous EEG studies have suggested reduced alpha band activity in patients with schizophrenia. Some recent studies using alpha α EEG guided TMS for treating positive and negative symptoms of schizophrenia have demonstrated promising results.
