Exploration of a brain cut in frontal section at the splenium of the corpus callosum
Dentato-rubro-thalamic pathway; substantia nigra; lateral geniculate body
The right brachium conjunctivum has been cut away nearly to its decussation. The red nucleus has been partially removed and the continuation of the dentato-rubro-thalamic pathway into the ventral lateral nucleus of the thalamus is visible. Just above the red nucleus these fibers lie in the tegmental field (H field of Forel) and above this is the fasciculus thalamicus (H 1 field of Forel).
1 . Fornix (crus) (cut across)
2 . Retroflex fasciculus
3 . H field of Forel (tegmental or prerubral field)
4 . Red nucleus (partially removed)
5 . Ascending fibers emerging from decussation of brachium conjunctivum (superior cerebelIar peduncle)
6 . Substantia nigra
7 . Brachium conjunctivum (superior cerebellar peduncle) (cut away further)
8 . Deep pontine fibers
9 . Medial lemniscus (cut across)
10 . Caudate nucleus (tail)
11 . Stratum zonale thalami (cut across)
12 . Thalamotemporal fasciculus
13 . Tapetum
14 . Ventral lateral nucleus of thalamus
15 . Ventral posterior lateral nucleus of thalamus
16 . Lateral geniculate body (cut across)
17 . Hippocampus (cut across)
18 . Cerebral peduncle
19 . Superior cerebellar artery (cut across)
20 . Root of trigeminal nerve (V) entering pons
