Brain: Facial colliculus Rhomboid fossa. (Colliculus facialis labeled at center left.) Human caudal brainstem posterior view (Colliculus facialis is #3) Latin colliculus facialis Gray's subject #187 799 NeuroNames hier-621 The facial colliculus is an elevated area located on the dorsal pons. In the floor of the 4th ventricle It is formed by motor fibers of the facial nerve as they loop over the abducens nucleus. Thus a lesion to the facial colliculus would result in facial muscle paralysis.
