			The primary function of the nucleus prepositus is to assist in the maintenance of [[gaze stability]]. It acts as an integrator for [[vestibular]] and [[visual]] inputs, helping to coordinate the [[vestibulo-ocular reflex]] (VOR).

'''Nucleus prepositus''' is a structure found in the [[brainstem]], specifically in the [[medulla oblongata]]. It plays a crucial role in the integration of [[vestibular]] and [[visual]] signals to control [[eye movement]]s.

== Anatomy ==

The nucleus prepositus is located in the anterior part of the medulla oblongata, near the midline. It is situated between the [[inferior olivary nucleus]] and the [[medial vestibular nucleus]]. The nucleus prepositus is part of the [[vestibular system]], which is responsible for maintaining balance and coordinating eye movements.

== Function ==

The primary function of the nucleus prepositus is to integrate vestibular and visual signals to control eye movements. It receives input from the [[vestibular nuclei]], the [[cerebellum]], and the [[retina]], and sends output to the [[oculomotor nuclei]] and the [[trochlear nucleus]]. This allows the nucleus prepositus to play a key role in the [[vestibulo-ocular reflex]], which stabilizes gaze during head movements.

== Clinical significance ==

Damage to the nucleus prepositus can result in a variety of [[neurological disorder]]s, including [[nystagmus]], [[vertigo]], and [[ataxia]]. These conditions can cause symptoms such as uncontrolled eye movements, dizziness, and loss of balance.
