Cortex-sparing fiber dissection of the ILF and temporal base in a right hemisphere. (A) In this hemisphere the cortex within the depth of the collateral sulcus and the occipitotemporal sulcus have been removed. The occipitotemporal or fusiform gyrus is located at the temporal and occipital base. (B) The stem of the occipitotemporal sulcus has been tilted with a dissector. (C) The stem of the occipitotemporal gyrus has been cut in a plane perpendicular to the direction of the gyrus stem, and the anatomic planes of cleavage between the fibers has been opened enabling us to follow the fibers until the cortical termination. (D) The dissections revealed that these fibers connected the fusiform gyrus with the posterior portion of the inferior occipital gyrus. 1, fusiform gyrus; 2, inferior temporal gyrus; 3, parahippocampal gyrus; 4, occipital pole; 5, temporal pole; 6, calcarine fissure; 7, inferior occipital gyrus. Ant, anterior; Post, posterior.
