Research Abstract

It is important that the auditory restoration to get stable hearing in the noisy world. The purpose of this research project was to examine effects of the prediction of the interruption timing on the auditory restoration, and to clarify the mechanisms that determine the prediction in the brain. We used the selective adaptation procedure to examine the selectivity of the prediction effects. We found that the prediction effect have not the frequency and aural selectivity. From these results, the prediction of the interruption timing determine after the integration between aural information and different frequencies information. I believe that these new findings should shed light on the mechanisms of the stable hearing in the noisy world.
