| Research Abstract |
The association fibers connecting the inferior and superior frontal gyri were analyzed using fiber dissection and MRI techniques. The fibers were anatomically identified to connect between the Broca center and the lateral superior frontal gyrus, and existed dominantly in left cerebral hemisphere and male population. The anatomical feature was common to that of the arcuate fascicle. These findings suggest a close relationship between this pathway and language organization, and may explain speech disturbances induced by lateral superior frontal gyrus stimulation that were sometimes observed during intraoperative language mapping.
