N2 - Even though how bilinguals process the second language (L2) still remain disputable, it is agreed that L2 processing involve more brain areas and activate common regions more strongly. It interested us to probe why heavier manipulation of cortical regions did not guarantee a high language proficiency. Since the responses of individual brain regions were inadequate to explain how the brain enabled behavior, we sought to explore this question at the neural network prospect via the Psychophysiological interaction (PPI) analysis. We found that Chinese English bilinguals adopted the assimilation/accommodation strategy to read L2, and English activated common brain areas more strongly. However, the whole brain voxel-wise analysis of effective connectivity showed that these brain areas formed a less synchronized network, which may indicate an ineffective neural network of L2. Our findings provided a possible explanation why the proficiency level of L2 was always lower than L1, and suggested that future fMRI studies may better explore language issues by depicting functional connectivity efficacy.
