This is the best view we will get of the cerebral peduncle, because at more caudal levels the fibers in the medial edge of the peduncle will pass into the basilar pons. In fact, as the sagittal view shows, the bottom of the slide passes through the rostral tip of the basilar pons.

Frontopontine fibers are said to form the medial fifth of the peduncle. Parieto-, temporo- and occipito-pontine fibers are said to occupy the lateral fifth and the middle three fifths of the peduncle is where the corticospinal tract runs.
