2 . Crura of fornix
3 . Laminae affixae
4 . Corona radiata (partially dissected)
5 . Head of caudate nucleus
6 . Anterior horn lateral ventricle
7 . Genu corpus callosum (dissected parallel to fibers)
8 . Superior frontal gyrus (cut in horizontal plane)
9 . Anterior cerebral arteries lying within longitudinal fissure
10 . Caudate nucleus (tail)
11 . Anterior tubercle of thalamus
12 . Remnants of superior longitudinal fasciculus
13 . Interventricular foramen left (of Monro)
