|Anatomical terms of neuroanatomy|
The facial colliculus is an elevated area located on the dorsal pons in the floor of the 4th ventricle. It is formed by fibers from the motor nucleus of the facial nerve as they loop over the abducens nucleus. Thus a lesion to the facial colliculus would result in ipsilateral facial paralysis and ipsilateral unopposed eye medial deviation.
