Parts of the left hemisphere adjacent to the central sulcus are further resected nearly to the lateral fissure. The arched course of the superior longitudinal fasciculus (9) can be seen lateral to the corona radiata (7). Posteriorly, as this fasciculus curves sharply downward into the temporal lobe, another wide band of fibers emerges (11) from under its cover and courses toward the occipital lobe. This latter consists in part of the visual radiation (geniculocalcarine tract) and in part of fibers of the inferior occipitofrontal fasciculus. These systems of fibers join the occipital radiations of the internal capsule and corpus callosum.
