目的：利用功能磁共振成像(fMRI)考察健康人双任务范式下汉字加工过程。方法10名健康受试者分别进行双任务范式的“按键朗读”任务及单任务范式的“按键”“朗读”任务。采用标准的组块相关设计对受试者大脑进行fMRI扫描，观察任务中脑功能激活区及偏侧化指数。结果和结论执行任务时，右侧额下回、双侧顶叶、双侧小脑显著激活；偏侧化指数显示，脑激活区呈现左半球优势。

Objective To investigate the Chinese characters processing in healthy subjects with functional magnetic resonance imaging (fMRI). Methods 10 healthy subjects were asked to finish the dual-task paradigm Keying/Reading and single-task paradign Keying or Read-ing. The active area and partial lateralization index in brains of them were investigated with fMRI with block design. Results and Conclu-sion The tasks activated the right inferior frontal gyrus, bilateral parietal and cerebellar cortex. The laterality index showed that the left brains were more active in the tasks.
