Exploration of the brain from its superior aspect
Cingulum
The cortex of the gyrus cinguli has now been scraped away to display the medullary substance which includes the cingulum, a large bundle of association fibers running longitudinally. The upper surface of the corpus callosum is partly exposed, its vessels and meninges remaining intact. Portions of the corona radiata are visible as cut ends of fibers projecting upward.
- Medullary substance of superior frontal gyrus
- Surface of cingulate gyrus facing cingulate sulcus
- Superior cerebral vein overlying central sulcus
- Central sulcus in depths of dissection
- Area of corona radiata

- Posterior parietal branch of middle cerebral artery
- Parieto-occipital branch of posterior cerebral artery (enclosed within the meninges of the parieto-occipital fissure)

- Superior frontal sulcus
- Cingulate gyrus (cut across)
- Precentral gyrus
- Central sulcus (Rolandic)
- Postcentral gyrus
