Summary

Repetitive transcranial magnetic stimulation (rTMS) is a new noninvasive therapy that uses magnetic energy applied to the scalp to modulate activity in the underlying regions of the brain. In this study we will examine the efficacy of treating auditory hallucinations in schizophrenia with rTMS, comparing two methods to target stimulation to a language processing region of the brain. One method targets the stimulation site using scalp landmarks, while the other uses functional magnetic resonance imaging (fMRI) combined with a language task.

Conditions

Interventions

PROCEDURE

rTMS with fMRI-based targeting

Inhibitory (low frequency) 1-Hz rTMS will be applied to the secondary auditory cortex during 10 daily 20-minute treatment sessions. An fMRI scan combined with a language task will be used to localize the secondary auditory cortex, followed by neuronavigation to identify the scalp location overlying the targeted cortex.

PROCEDURE

rTMS with landmark-based targeting

Inhibitory (low frequency) 1-Hz rTMS will be applied over the left temporoparietal cortex (TPC) during 10 daily 20-minute treatment sessions, with the stimulating coil located midway between the left temporal (T3) and parietal (P3) scalp landmarks, using the International 10-20 system for EEG.
