Electroencephalography Correlates in Tinnitus

Author(s): Elmar W.J. Weiler, Klaus Brill, Ken H. Tachiki and Rainer Wiegand

This study was conducted in an attempt to determine whether the quantitative electroencephalograph activity differs between normal control subjects and subjects suffering from tinnitus. Results indicated that male tinnitus patients as a group had a significantly reduced average total power as compared to control subjects. This finding contrasted with female tinnitus patients, who as a group had a higher average total power as compared to normal female control subjects. Topographical maps (control value-tinnitus value) indicate that with male patients, the frontocentral regions of the brain show the greatest difference. For the female tinnitus patients, the brain regions most affected are the central, parietal, temporal, and occipital regions.
