Children’s New Word Processing Features And The Development Of Resting State Networks

Early and late words of acquisition is an important area of language brainimaging studies,but there is considerable controversy about its exact age.Thefunctional network is is an important breakthrough in the language development, theresting state technology has recently become an important means of functionalnetwork, but the study of resting state network on Chinese language processing isseldom. Therefore,This article take advantage of this newly acquired vocabulary andfMRI resting state technology to study the language processing networkabout children and adults. Experiment1explored the brain regions of the acquisitionterms of the sixth grade about children’s processing, tasks include the homophonejudgment and the judgment of true and false words, rendered in visual mode.14subjects participated in the fMRI data acquisition. The results of children in thejudgment of the homophone judgment and true and falsewords activated the leftprecentral gyrus, but did not activate the left inferior frontal gyrusand left temporalgyrus,this suggest The left precentral gyrus has the the function of processing ofnew words and late written. Homophone judgments also activated the right MedialFrontal Gyrus，while the judgment of true and false words activated the leftcingulate Gyrus and the left Inferior Parietal Lobule. The correlation matrix of the twotasks left-right brain connection show the left-right brain connection, andhomophone judgment showed frontal-right brain networks, rather than frontal-temporal network. The ROI analysis of Seed point to the left precentral gyrusactivate brain regions including the left superior temporal gyrus, left inferior frontalgyrus, left middle frontal gyrus, right superior frontal gyrus，left inferior parietallobule and other brain regions,And The correlation matrix displays to the left superiortemporal gyrus and left inferior frontal gyrus close to the high correlation, the leftsuperior temporal gyrus and left inferior parietal lobule close to the high correlation,the left middle frontal gyrus and left inferior parietal lobule to achieve highcorrelation,suggest that the child has a high correlation among the frontal-parietal-temporal network. Two tasks do not activate the left superior temporal gyrus，Furtherproviding evidences that sound and meaning of Chinese words are not isolated，leftsuperior temporal gyrus Process Chinese semantic rather than phonological. the childhas a high correlation among the frontal-parietal-temporal network indicating that children’s mainly auditory language processing. In this study, Chinese languageprocessing is the frontal-right brain networks, rather than like English is thefrontal-temporal or the frontal-the parietal network.In Experiment2, the left superior temporal gyrus (BA22), left inferior frontalgyrus (BA45),left middle frontal gyrus, right BA10/11seed point, Conducted fMRIresting state analysis, including14sixth-grade children and14college studentssubjects，the task is to rest, and then resting state scan, record their languagefunctionsof the brain regions ligation. The result is that the development trend of theleft superior temporal gyrus (BA22) and the left inferior frontal gyrus (BA45)showed the opposite situation, with age Increasing, the left temporal gyrus networkwill be reduced, and are not highly correlated, while the left inferior frontal gyrusnetwork will be increased, and adult are high correlation. This shows that Chineseprocessing network is a frontal-based, rather than the temporal lobe-based, andchildren more than adults, the use of auditory speech processing. The developmenttrend of the relevant network about left middle frontal for children is not yet mature,the adult has been formed, the combination of the left superior temporal gyrus and leftinferior frontal gyrus of adult activated the left middle frontal gyrus shows that theadult language processing network is mainly the left middle frontal gyrus, and thechildren is mainly the left inferior frontal gyrus. the rest statistical analysis aboutRight BA10/11shows that the majority of its network are non-specific brainregions, their specific functions to be studied.In short, the two experiments shows that the left central gyrus has the function ofprocessing new words、late written. the processing network of Chinese language is thefrontal-right brain networks, rather than the frontal-temporal network,and thechildren is mainly left inferior frontal gyrus processing network, while adults ismainly left middle frontal gyrus.
