Dorsal to the decussating fibers of the mesial fillet ( Mf) and ventral to the central gray matter (Cen) is an important bundle of fibers, the posterior longitu- dinal fasciculus ( PL). Ventrolateral to the central gray matter may f^e seen a large collection of gray substance constituting the griseal portion of the reticular formation.
