Zusammenfassung

Tinnitus is the perception of sound in the absence of any external auditory stimulus. Based on previous research we have proposed a framework which postulates that the reduction of ongoing inhibitory alpha activity in tinnitus subjects favors a synchronization of neurons in the gamma frequency range while in a resting state. In the presentworkwe are validating the existence of an inverse relationship between auditory gamma and alpha activity in tinnitus and control subjects using Magnetoencephalography. Tinnitus subjects exhibited a significantly steeper slope of the regression line compared to controls, presumably because a greaternumber of subjects concurrently exhibited lowalpha and high gammapower. Therefore, the role of the alpha gamma pattern is discussed regarding its possible implication for the generation of tinnitus.
