摘要
目的:用功能磁共振成像的方法研究汉字语义加工的脑功能区定位,着重讨论男性和女性语义加工时是否存在性别差异。方法:15例右利手大学生,男7例,女8例,执行汉字同义词判断任务,同时采集其脑部的fMRI数据,采用SPM99进行数据分析,得到相关脑功能区,并对男性和女性语义任务时的脑激活区进行比较。结果:男性激活的脑区包括双侧额下回、左额中回、左颞上回及双侧小脑。女性激活的脑区包括双侧额下回、左额中回、双侧颞上回及双侧小脑。两者脑活动区直接比较,在进行语义任务的时候男性仅激活左侧颞上回,而女性可激活两侧颞上回。结论:男性和女性在进行汉字语义加工任务的时候,两者激活的脑区不完全相同,女性激活的脑区比男性广泛。
Objective:To detect the location of the brain activations during Chinese characters reading using fMRI and to investigate the difference of the fMRI activation patterns of males and females during semantic processing.Methods:fMRI was studied on 15 right handed students during performing Chinese synonym judgement tasks,data analysis was carried out using spm 99.FMRI activation patterns of males and females in semantic processing were compared.Results:In males the activating areas were shown bilateral inferior frontal gyrus (IFG),left middle frontal gyrus,left superior temporal gyrus (STG) and bilateral cerebellum.In females the activating areas included bilateral IFG,left middle frontal gyrus,bilateral STG and bilateral cerebellum.The males only activate left STG while the females activate bilateral STG. Conclusion:Our findings reveal that the activating areas in males and femals during Chinese characters semantic processing are not totally identical,the activating areas in females are more entensive.
