(FRAME-INFO (STRING "Descending Fibers: Midbrain and Pons. The corticospinal tract \(blue line\) passes through the midbrain and pontine levels of the brainstem in a ventral position. Corticobulbar fibers \(green lines\) accompany the corticospinal tract. \(The number of lines does not represent the relative sizes of the tracts\). In the base of the pons, both tracts separate into fascicles and pass between groups of pontine nuclei.  A corticobulbar fiber is shown as it crosses and synapses in the trigeminal motor nucleus \(or interneurons nearby\). Note: corticobulbar axons may leave the basal region and follow an aberrant course, descending near the medial lemniscus."))
