The language anatomical model proposed that Brocas area located in the inferior frontal lobe and Wernickes area located in the superior temporal gyrus were connected through the arcuate fasciculus (AF). Hickok and Poeppel [1] and others recently proposed a dual stream model for auditory language processing. From the superior temporal gyrus, which is engaged in early cortical stages of speech perception, the system diverges into two processing streams. The aim of this study is to examine the language circuits of the dual stream model using visual perception by an integrated functional MRI (fMRI) and probabilistic diffusion tensor imaging (pDTI) method.
