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.
