Anatomical terms of neuroanatomy

The frontopontine fibers[1] are situated in the medial fifth of the base of the cerebral peduncles; they arise from the cells of the frontal lobe and then pass through the anterior limb of internal capsule at last end in the nuclei of the pons.

The frontopontine tract (tractus frontopontinus) refers to the combination of the fibers.
