The three cerebellar peduncles are present at this level. Lateral to the inferior peduncle are the fibers of the middle peduncle .Medial to it are the fibers of the superior one. On the contralateral (right) side, fibers of the ventral spinocerebellar tract are moving dorsally, getting ready to "run over the top" of the right superior cerebellar peduncle, cross the midline, and turn caudally "on top of" the left superior peduncle to enter the cerebellum. See Figure 6-16.
