【摘要】 采用读词名的方法 ,对 12名正常大学生 ,运用功能性磁共振成像技术 (fMRI) ,研究了汉字词及假词视觉识别时的脑功能偏侧化现象。实验结果表明 ,汉字词激活左下额区 (BA4 5 )以及右颞叶 (BA2 1、2 2 )、右枕叶 (BA18) ,而假词除额区外表现出广泛的激活。此结果显示除左脑半球与汉字词加工密切相关外 ,右脑半球在汉字词加工中有一定参与但其确切作用有待进一步研究更多还原

【Abstract】 Functional magnetic resonance imaging was used to examine the lateralization of the cerebral hemisphere during the naming of Chinese single characters and pseudowords with twelve normal students. The result indicated that Chinese single characters activated the left inferior frontal cortex (BA45) but pseudowords did not. This result showed that Chinese word processing is close to the left hemisphere. The right hemisphere was also involved in processing but its mechanism needed to be further studied.更多还原
