The decussation is completed at the level of the superior borders of the inferior colliculi, and then each brachium proceeds upwards into the superior part of the tegmentum, where it en- counters the red nucleus. Into this a large propor- tion of its fibres plunge, and come to an end in connexion with the nuclear cells. Many of the fibres, however, are carried around the nucleus so as to form for it a Lateral geniculate body Inferior brachium Medial geniculate body Medial lemniscus â --ââ Basis peduncul Optic tract âAs the brachia conjunctiva leave the pons and sink Inferior colliculus.
