摘要/Abstract

摘要： 目的采用脑磁图(magnetoencephalography,MEG)的等价偶极子定位法(equivalent current dipole,ECD)和合成孔径磁场定位法(synthetic aperture magnetometry,SAM)定位母语为汉语健康自愿者的听觉性语言中枢,探讨汉字的语言加工过程.方法对15例母语为汉语的健康受试者采用北京大学附属第一医院制定的利手评定标准进行利手评定,采用给予听动物名称、植物名称的语言任务刺激,用MEG记录刺激后产生的诱发磁场,将采集的数据与MRI叠加,定位听觉性语言中枢.结果所有受试者听到动物名称、植物名称后均在双侧大脑半球诱发出明显的晚发磁反应波,其中左侧大脑半球磁反应波分化较右侧大脑半球好.结论母语为汉语的正常人听觉性语言中枢与经典的语言中枢基本相符,即听觉性语言中枢定位于左侧颞中回、颞上回、缘上回.

Abstract: Objective To do mapping and locate the linguistic center of auditory function in volunteers whose native language is Chinese by equivalent current dipole(ECD) and synthetic aperture magnetometry(SAM) of magnetoencephalography(MEG) in order to reveal the language processing of Chinese.Methods Fifteen volunteers undertook handedness assessment of Aphasia Battery of China.They also listened animal's names and plant's names silently.We recorded the induced magnetic field and added the collecting data to MRI to locate the linguistic center of auditory function. Results Fifteen volunteers are all right handed.We found late magnetic reaction waves in two hemisphere of these volunteers after hearing animal's names and plant's names and the left hemisphere waves were more differential than that of right hemisphere.The results showed that the linguistic center is located at middle temporal gyrus,superior temporal gyrus and supramarginal gyrus.Conclusion The linguistic center of auditory function in Chinese people coincides with the classic language center,ie.is located at middle temporal gyrus,superior temporal gyrus and supramarginal gyrus.

Key words: native language, Chinese, linguistic center of auditory function, magnetoencephalography
