摘要： 为了研究人类大脑皮层对飞机飞越噪声的表达机制，采用功能磁共振成像(fMRI)技术，选择 25 例正常健康受试者，观察在飞机飞越噪声刺激时大脑功能区的激活情况，通过对数据进行统计学处理以及脑功能区定位，结果表明：25 例受试者在飞机飞越噪声刺激时大脑显著激活了视觉联合皮层、前额叶皮层、初级运动皮层以及与认知记忆相关的脑区等.飞机飞越噪声刺激下，大脑皮层听觉区域不仅参与了听觉处理，可能还涉及消极情绪、认知、注意、记忆等区域反应.

Abstract: In order to study the cognitive mechanism of human cerebral cortex on aircraft flyover noise, 25 healthy subjects were studied and functional magnetic resonance imaging (fMRI) technique was carried out. The data were processed statistically and the brain functional regions were located. The results have shown that 25 subjects significantly activated the visual combined cortex, prefrontal cortex, primary motor cortex, and brain regions associated with cognitive memory, which means the cerebral cortex is not only involved in the auditory treatment, may also involved in negative emotions, cognitive, attention, memory and other reactions.
Key words: aircraft flyover noise, cerebral cortex, functional magnetic resonance imaging (fMRI) techno-logy, cognitive mechanism
