White Matter Differences between Bilinguals & Monolinguals Revealed by Diffusion Tensor Imaging (DTI)

Seyede Ghazal Mohades^1,2, Esli Struys¹, Robert Luypaert²

This study is aimed to find differences in the structure of white matter of the brain between monolinguals and bilinguals. MR-DTI based tractography is used to track three sets of fibers in the areas that are of interest in linguistic studies (i.e. betwwenBrocas and Wernickes areas, between brocas area and corpus callosum and from anterior midbody of corpus callosum to primary motor cortex ). The results show that there is significant difference in FA value of fibers connecting Brocas to Wernickes area and also the fibers that connect Brocas area to corpus callosum between these two groups.
