Abstract:
Objective To research the neural substracts for the processing of the discourse-level English writing using PET-CT.Method Six healthy people underwent 18F-FDG PET examination in the pseudo-writing condition and the discourse-level English writing condition.statistical parametric mapping(SPM)was used to investigate the activicated focus in english writing thruugh pared-t test.Results The activated foci were observed in left inferior parietal lobule,left postcentral gyrus,left cingulate gyrus,left putamen,fight frontal precentral gyrus,right superior frontal gyrus,right thalamus medial dorsal nucleus,both cerebellum(P＜0.05).Conclusions The writing of English as a second language implicates conical and subcortical structures.Left inferior parietal lobule,right frontal and both cerebellum participate in the language production and processes,and left putamen is more engaged in English learning.
