摘要

本文旨在探讨与视觉-听觉整合相关的特定皮层区域。在同步和非同步两种情况下的节奏游戏中，fNIRS获得了皮层活动。9名受试者参加了实验。组分析结果显示，听觉和视觉刺激的时间差影响皮层激活的变化，表现为氧合血红蛋白浓度的变化。除布洛卡区外，右半球皮层的激活程度明显高于左半球。颞上回(STG)和颞中回(MTG)是直接参与视觉-听觉整合加工的皮层区域。

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.
