| Zusammenfassung | The integration of different sensory streams into a coherent, conscious percept is required for multisensory perception, where in human brain the superior temporal gyrus (STG) plays an important role. In this combined MRS-EEG study, the sound-induced flash illusion (SIFI) paradigm was applied to test the hypotheses that the GABA concentration in the STG predicts multisensory perception at the behavioral level and gamma-band activity during SIFI. MRS data were acquired using MEGA-PRESS at 3T, and EEG signals were recorded for 40 subjects. The hypotheses were confirmed, and a tight triangular relationship between GABA concentration, gamma-band oscillations, and multisensory perception was found. |
