A FMRI Stduy Of Chinese Pinyin

As the medium of thinking,language is considered to be one of the most essential attributes shared by all human beings,which is closely associated with other cerebral cortical functions,such as perception,attention,memory and so on, and thus emphasized by researchers from interdiscipline and multi-level.Through integration of neural actions and higher-order resolution technique of MRI,fMRI can picture higher-order cortical function centers for human brain accurately,which makes possible the determination of high cortical actions of cerebrum from function and morphology under living conditions.In our experiment,fMRI is going to be employed to define the cerebral activation patterns concerned with processing of Chinese pinyin reading,determinating distribution of associated cortical centers for such processes,and so we would reach a novel perspective for in-depth understanding of human cognitive patterns.10 native Chinese college students with confirmed right-handedness were recruited.By means of looking,these subjects were required to finish reading tasks of Chinese pinyin(real and false) separately.Block designing was performed in this experiment.Every subject should fulfill two run tasks.BOLD efficacy,fMRI was available to collect functional images with EPI.The goal was to identify the cerebral activation distribution patterns under such two kinds of pinyin.All subjects demonstrated significant activation of associated cerebral regions. Real pinyin reading processing activated bilateral Cuneus(BA17,18);bilateral Lingual Gyrus(BA17);right Medial Frontal Gyrus(BA10);bilateral Midddle Frontal Gyrus(BA9) and Middle Occipital Gyrus(BA18);left Middle Temporal Gyrus;left Precentral Gyrus(BA6);right Paracentral Lobule;right Precuneus and Superior Frontal Gyrus(BA8).False pinyin reading processing activated bilateral Cuneus(BA17,18,19);left Lingual Gyrus(BA17);bilateral Medial Frontal Gyrus(BA9,10);right Midddle Frontal Gyrus(BA9);bilateral Middle Occipital Gyrus(BA18,19);left Precentral Gyrus(BA6) and Postcentral Gyrus.Base on analysis of the results,our study indicated that the "pseudoword" which we made up was doable.The brain with pinyin reading showed different activated patterns to previous studies.BA9 which was considered to be special to Chinese was also activated in this study,the function of BA9 needs farther discussion.
