ateral View of the Brain Centered at the Level of the Intraparietal Sulcus. A, Lateral view of the brain centered at the level of the intraparietal sulcus. In this phase, the gray matter has been removed from part of the superior parietal lobe (SPL), supramarginal gyrus (SPMG), and angular gyrus (AG) to show the short association U fibers. This dissection is performed with a lot of previous white matter dissection technique experience. All the labeling comes from previous knowledge. B, Panoramic side view of the entire cerebral surface to show the U fibers. Red circle shows the boarding area centered on the intraparietal sulcus. (Image courtesy of E de Oliveira)
