The nucleus prepositus or nucleus prepositus hypoglossi is one of the largest of the three perihypoglossal nuclei. It is situated in the caudal pons and rostral medulla oblongata. It contributes to several aspects of gaze control including the horizontal gaze holding system.
Injury to the nucleus prepositus results in inability to hold gaze upon a visual target; conjugate eye movement is unaffected.
It may be conceptually regarded as a vestibular nucleus.
