Lateral View of the Brain With a Window Centered at the Level of the Intraparietal Sulcus. A, Lateral view with a window centered at the level of the intraparietal sulcus (IPS). After removing the superior longitudinal fascicle (SLF) II and vertical occipital fasciculus (VOF), the dorsal arcuate fascicle (AF) (fibers with an inverted C shape) and the posterior fibers of the sagittal stratum are exposed. All the labeling comes from previous knowledge. B, Panoramic side view of the brain identifying the dorsal and ventral arcuate fascicle. The anterior fibers of the medial longitudinal fasciculus (MdLF) are identified before its fusion to the sagittal stratum. Red circle shows access region in A. C, Panoramic side view after arcuate fascicle removal to expose the sagittal stratum. The fusion of the medial longitudinal fasciculus to the sagittal stratum is identified from the posterior insular point. Red circle shows access region in A. (Images courtesy of E de Oliveira)
