Description
Summary:It is said that the auditory spatial perception is strongly affected by visual cues, and when auditory and visual stimulation are given from different positions simultaneously, the source position of sound is mislead to the direction of visual stimulation. The purpose of this study is analyzing the brain response on f-MRI by simultaneous stimulation of auditory and visually sensors. f-MRI of some subjects were measured by using simultaneous stimulation, and the results of these experiments were analyzed and assessed. From these experiments, following characteristics became clear. 1) Simultaneous stimulation activate each cortex stronger than the results of single stimulation. 2) Simultaneous stimulation activate right cerebellum. From investigation of these results, it seems that the relationship between auditory and visual cortex become clear.
