Exploration of the cerebellum and brain stem from the medial aspect

Lateral lemniscus; medial lemniscus; course of trigeminal nerve through pons

The brachium conjunctivum has been partly removed and the tegmentum of the mesencephalon further dissected. The pigmented border of the substantia nigra (8) remains, but much of this nucleus was scraped away to demonstrate the cerebral peduncle (7). From the lower border of the substantia nigra white fibrous tissue appears to continue into the tegmentum of the pons.
