5. Study Description

Brief Summary
The purpose of this study is to determine whether rTMS are effective in the treatment of tinnitus
Detailed Description
Repetitive transcranial magnetic stimulation (rTMS) of the dorsolateral prefrontal cortex (DLPFC) has an add-on effect for primary auditory cortex rTMS in improving tinnitus-related distress. We aimed to investigate whether rTMS of the dorsolateral prefrontal cortex and primary auditory cortex are capable of reducing tinnitus loudness. Linked to a neuronavigation system that is guided by magnetic resonance imaging (MRI) of the frontal and temporal, rTMS can suppress areas of cortical plasticity. This cortical reorganization can be demonstrated by magnetoencephalography (MEG)
