多语者第二语言脑加工的功能磁共振成像

目的 研究多语者默读英语时,脑的功能活动.方法 12名广州话母语右利手大学生,男7女5,年龄21～22岁.默英语单词,运用功能性磁共振成像对作业过程中的被试进行扫描,用AFNI软件对数据进行统计分析.结果 执行英语单词默读作业时,小脑,右(BA18),右颞叶下部(BA20),左前额叶下部(BA47),左前额叶中部(B10),右豆状核,左前额叶上部(BA9),左前额叶上部(BA6)有明显激活.结果 显示,左侧额叶与英语加工有关,右侧颞叶、小脑参与.结论 英语加工,多语者布洛卡脑区激活不显著,主要分布在其他区域.

Second Language Brain Process of Multilingual Students Functional Magnetic Resonance Image Study

Objective Functional magnetic resonance imaging was used to examine the brain activation during the naming of English single words by multilingual students. Methods The participants were 12 Guangzhou native tongue university students. Seven were males five were females, with ages ranging from 21 to 22 years old. Block design statistics software used Analysis of Functional Neuroimage (AFNI, Cox et al, 1996). Results Right Declive, Right Lingual Gyrus (BA18), Right Inferior Temporal Gyrus (BA20), Left Inferior Frontal Gyrus (BA47), Left Middle Frontal Gyrus (BA10), Right Putamen, Left Superior Frontal Gyrus(BA9), Left Superior Frontal Gyrus (BA6). This result showed that English word processing is close to the left Frontal Gyrus. The right Temporal Gyrus was also involved in processing. Conclusion Activate brain area of Broadmann 47 not big to Multilingual students That Mainly distribute in other areas.
