为探讨情绪音乐对视觉加工的影响，对14名健康受试者听情绪音乐时的视觉诱发磁场(VEF)进行了分析。在VEF录制期间，通过情绪中性的面孔和风景图片进行刺激，播放积极和消极的音乐片段。分析刺激开始后100(M100)和150(M170)ms的VEF成分，与MUSIC阳性相比，面部刺激后M170的电流强度估计值在右侧大脑半球增强。分别在初级视皮层(V1)和颞下区(IT)计算M100和M170的等效电流偶极子。本研究结果表明，背景音乐对信息技术中的视觉过程具有自上而下的控制作用，而信息技术是负责面部表情理解的核心区域。音乐的情感内容可以改变视觉过程，特别是涉及面部的视觉过程。
To investigate the effects of emotional music on visual processes, we analyzed visual evoked magnetic fields (VEF) on listening to emotional music in 14 healthy subjects. Positive and negative pieces of music were delivered during VEF recording following stimulation by emotionally neutral pictures of faces and landscapes. VEF components at 100 (M100) and 150 (M170)ms after stimulus onset were analyzed, and the estimated current strength for M170 following face stimulation was enhanced with negative compared to positive music in the right hemisphere. The equivalent current dipole for M100 and M170 was estimated in the primary visual cortex (V1) and inferior temporal area (IT), respectively. The present results indicate that background music showed a top-down control of the visual processes in IT, which is a core site responsible for the interpretation of facial expression. The emotional contents of music could alter visual processes, especially those involving the face.
