Cortical Regions Associated with Visual-Auditory Integration: an fNIRS study
This paper is to explore the specific cortical regions associated with a visual-auditory integration. Cortical activities were acquired by fNIRS during rhythm game which offered visual-auditory stimulation with synchronous and asynchronous situations. Nine subjects have participated in the experiment. The results from group analysis showed that time difference between auditory and visual stimuli affected the change of cortical activation in terms of the concentration change of oxygenated hemoglobin. Especially, the cortical activation went higher in right hemisphere than left hemisphere except Broca’s area. Superior Temporal Gyrus (STG) and Middle Temporal Gyrus (MTG) were observed as the cortical regions directly engaged in human visual-auditory integration processing.
