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. Thus a lesion to the facial colliculus would result in ipsilateral facial paralysis and ipsilateral unopposed eye medial deviation.

gollark: Wow, this new material was a great idea, thanks <@!293066066605768714>.
gollark: But lists are mutable, so it appended to the list fine, but `+=` tries to mutate the tuple, which python does not like, so it errors AFTER that.
gollark: No, it did error.
gollark: I mean, I like it *generally*, but seriously why.
gollark: It's easy to use at the cost of apioidal weirdness, thus kind of bad in some ways.
