The investigation of cerebral activation for English semantic judgment task in Chinese by fMRI
Objective: To determine the cerebral activation patterns associated with processing of English semantic judgment task by fMRI in native Chinese bilinguists.Methods: 12 native Chinese bilinguists were divided into two groups with 6 in each group
English-specialized and non-English-specialized group
and performed English words semantic judgment task
whose fMRI images were collected.Results: All subjects demonstrated significant activation of associated cerebral regions.Besides classical regions involved in language processing
such as Wernicke and Broca areas
there were other activated cerebral regions
including cerebellum
limbic system and basal ganglial nucleus
etc.The analysis of ROI implied that subjects in the specialized group were more dependent on the right hemisphere.Conclusions: Left hemisphere dominates in language cognition
although which is also related to the right hemisphere to various degrees.Two hemispheres work by ways of both dissociation and coordination.It is possible that working strategy of the right hemisphere is related to proficiency of the second language.A variety of distinctions are shared by each subject for language cognitive patterns.
