In this sagittal section lateral to the midline can be seen the Rolandic fissure with the precentral gyrus (motor cortex) and the postcentral gyrus (somesthetic cortex). The frontal lobe, the parietal lobe, and the occipital lobe are well demarcated. The caudate nucleus, the pulvinar of the thalamus, and the lateral geniculate nucleus are seen. The dentate nucleus of the cerebellum is prominent.
