Exploration of the brain from its superior aspect
Right centrum semiovale
The right hemisphere has been cut horizontally just above the level of the body of the corpus callosum. The centrum semiovale is displayed and a number of important relationships of surface landmarks to deeper structures may be studied.
- Superior frontal gyrus
- Medial frontal gyrus
- Inferior frontal gyrus
- Dissected fibers of corpus callosum
- Caudate nucleus
- Septum pellucidum
- Insula (partially dissected)
- Emerging fibers of internal capsule
- Anterior tubercle of thalamus
- Choroid plexus lateral ventricle
- Lamina affixa
- Fornix (crus)
- Deepest fibers of corpus callosum (splenium)
- Inferior horn of lateral ventricle
- Cerebellum
- Lingual gyrus (cut across)
- Frontal pole
- Superior frontal sulcus
- Cingulate sulcus
- Cingulate gyrus (labeled at anterior and posterior limits, the gyrus being sectioned longitudinally between the points labeled)
- Inferior frontal sulcus
- Radiating fibers of internal capsule
- Cingulum
- Superior longitudinal fasciculus
- Lateral cerebral fissure (sylvian)
- Superior temporal gyrus
- Corpus callosum (splenium)
- Inferior parietal lobule (guide line in the area of confluence of the angular gyrus and the supramarginal gyrus)
- Superior temporal sulcus
- Precuneus and parieto-occipital fissure
- Occipital part corona radiata (the geniculocalcarine tract and various association fiber systems pass to the cortex of the occipital lobe through this area)
- Cuneus
- Lateral occipital gyri
