Exploration of the brain from its superior aspect

Close-up view of anterior part of lateral ventricle and interventricular foramen

Close-up view of central area of preceding stage of dissection seen from a more lateral angle. Details of the medial wall of the lateral ventricle and of the interventricular foramen are now evident. Note the small cavity of the septum pellucidum which has been cut open just beneath the corpus callosum. The ependymal lining of the ventricle is intact.

2. Medullary substance of inferior frontal gyrus
3. Junction of fibers from internal capsule and corpus callosum to form corona radiata (seen in cross section)
4. Anterior horn lateral ventricle
5. Superior occipitofrontal fasciculus
6. Head of caudate nucleus
7. Frontal branch of middle cerebral artery
8. Area of fibers derived from medullary substance of insula, external capsule and internal capsule (fibers course in various directions)
9. Emerging fibers of internal capsule
10. Insula
11. Artery of precentral sulcus
12. Artery of central sulcus
13. Transverse temporal gyrus
14. Cingulate gyrus (cut across)

16. Genu corpus callosum
17. Cingulum (cut across)
18. Cut edge of corpus callosum
19. Cavum septum pellucidum
20. Cingulate sulcus
21. Septum pellucidum
22. Interventricular foramen (of Monro)
