(A–D) Cortex-sparing fiber dissection of the AF in a right hemisphere. This figure shows how cortex-sparing fiber dissection enabled us to isolate this deeper bundle without destroying the superficial components of the fascicle. The fibers of this bundle have a postero-superior orientation, they curve around the caudal end of the Sylvian fissure to take an anterior orientation, then they run within the white matter of the parietal and frontal operculum and terminate at the frontal operculum. 1, AF; 2, temporal lobe; 3, frontal lobe. Ant, anterior; Post, posterior.
