摘要
目的探讨功能经颅多普勒超声(fTCD)研究汉语为母语的右利手中国成人语言偏侧半球的方法;探讨汉语为母语的右利手中国成人语言偏侧化及偏侧化程度。方法共招募2016年6月~2016年8月健康右利手志愿者95例。参与者在进行汉语语义流畅任务的同时被监测并记录双侧大脑中动脉血流速度。最终偏侧半球及偏侧化程度的评价由大脑偏侧化指数(laterality index,LI)进行,其数值正数代表左侧半球优势,其数值负数代表右侧半球优势,绝对值越大代表偏侧化程度越大,0代表没有偏侧化。结果共有67.4%的参与者显示左侧半球优势;且左侧半球优势参与者平均LI为(5.85±2.31),右侧优势半球参与者平均LI为(5.32±1.63),二者无差异(P>0.05);男性、女性在语言偏侧的方向及程度上无差异。结论f TCD可以作为研究汉语为母语中国人语言优势侧的方法之一。
Objective To explore the method of the language lateralization in Chinese native adult speakers using functional transcranial doppler(f TCD),and to research the direction and the degree of language lateralization in Chinese native adult speakers.Method A total of 95 healthy volunteers,who were admitted from June 2016 to August 2016.Participants were also monitored for the flow velocity of the middle cerebral arteries while performing the semantic fluency task in Chinese.The LI describing both hemispheric dominance and degree of lateralization.The positive value represents the left domination,the negative value represents the right domination,the greater of the absolute value means the greater of the lateralization,zero means no lateralization.Results The participants showed left domination accounted for 67.4%;the average LI of the left domination was 5.85±2.31,while the average LI in the right domination was 5.32±1.63,and there was no difference between the two kinds of dominations(P>0.05);there was no difference between men and women in the direction and the degree of language lateralization.Conclusion f TCD can be used as one of the methods to study Chinese language lateralization.
