Abstract:To explore the differences of effective connectivity while verbal generation task is respectively performed by people in Chi -nese (NH group) as well as in Uighur (NW group).Functional MRI data was acquired when verbal generation task was conducted on n-ative Chinese and native Uighur volunteers .After detecting the activated brain region , we selected the left Caudate (CAU.L) as ROI(re-gion of interesting ) , then chose the Granger Causality Analysis to perform the effective connectivity analysis .Compared with NW group , NH group showed increased inflows from the right frontal and parietal lobe , as well as the left frontal , limbic and occipital cortex to CAU.L.Besides, NH group also showed increased outflows from CAU .L to the right cingulate cortex and middle temporal cortex .While performing the verbal generation task , NH group shows increased effective connectivity between CAU .L and the regions related to visual sense, memory and semantics .NH group invokes more brain regions and shows more complicated information flows while carrying out the verbal generation task , it is presumed that NH group exists a more complex neural mechanism of language than NW group .
