汉语量词加工的脑功能磁共振研究

目的:通过考察大脑在加工量词时的活动情况,探讨量词加工的相关功能区及不同量词功能区可能存在的差异.方法:对18名健康志愿者行名量词和动量词语义(正确与错误)判断任务,比较不同任务各脑区激活强度及范围的差异.结果:名量词主要激活区域:双侧额中回、左侧额下回、双侧扣带同、双侧楔叶、楔前叶、双侧角回、双侧颞下回、左侧颞中回、舌回、右侧小脑.动量词主要激活的区域:双侧颞中回、双侧颞下回、双侧扣带回、双侧基底节、双侧角回、双侧额中回、左侧额下回、左侧岛叶、双侧小脑.结论:动量词与名量词激活的区域大部分较为一致,两者激活强度上存在差异.但是它们都需要双侧大脑半球各脑区相互协调合作.

A fMRI study of the processing of classifiers in modern Chinese

Objective:To explore the relative functional area of dealing classifiers and potential difference in various functional area by investigating the activation of brain when it deals with quantitative words. Methods:Eighteen healthy volunteers were asked to perform a nominal and verbal classifiers semantic decision tasks(to be wrong or to be right) during fMRI scanning in order to compare the difference in extent of different cerebal activation. Results:The major activating brain regions for nominal classifiers:left and right middle frontal gyrus,left inferior frontal gyrus,left and right cingulate gyrus,left and right cuneus,precuneus,left and right angular gyrus,left and right inferior temporal gyrus,left middle temporal gyral,lingual gyral,right cerebellar. The major activating brain regions for verbal classifiers:left and right middle temporal gyral,left and right inferior temporal,left and right cingulate gyrus,left and right basilar nucleus,left and right angular gyrus,left and right middle frontal gyrus,left inferior frontal,left insula,left and right cerebellar. Conclusion:The major activating brain regions for nominal and verbal classifiers are same. There is some difference in extent of cerebal activation. However,they all need co-ordinated operation of each functional regions on both cerebal hemisphere.
