Primary Outcome Measures
NameTimeMethod
<p>The main study parameter will be the cortical hyperactivity in tinnitus<br /><br>patients compared to control subjects in FDG-PET, analysed with SPM5. Our<br /><br>estimation is that this cortical hyperactivity is localised in the primary<br /><br>auditory cortex and the associative auditory cortex, although other regions<br /><br>might display some hyperactivity as well</p><br>
Secondary Outcome Measures
