Facial colliculus
The facial colliculus is an elevated area located on the pontine tegmentum (dorsal pons) in the floor of the fourth ventricle. It is formed by fibers from the facial motor nucleus of the facial nerve (cranial nerve VII) as they loop over the abducens nucleus.

Clinical Significance
A facial colliculus lesion would result in ipsilateral facial paralysis (i.e. Bell's Palsy) and inhibited ipsilateral and unopposed contralateral eye deviation.[1]
