Vestibular nuclei

Vestibular nuclei are a group of neurons located in the brainstem that play a crucial role in maintaining balance and eye movements. They receive input from the inner ear's vestibular system, which monitors the body's position and movement in space.

Anatomy

The vestibular nuclei are located in the medulla oblongata and pons, two regions of the brainstem. They are divided into four main nuclei: the superior, lateral, medial, and inferior vestibular nuclei. Each of these nuclei has a unique set of connections and functions.

Function

The primary function of the vestibular nuclei is to process sensory information about balance and spatial orientation. They receive input from the semicircular canals and otolith organs of the inner ear, which detect changes in head position and movement. This information is then sent to various parts of the brain and spinal cord to coordinate eye movements and maintain balance.

Clinical significance

Damage to the vestibular nuclei can result in a variety of symptoms, including dizziness, vertigo, and problems with balance and coordination. Conditions such as vestibular neuritis and Meniere's disease can affect the function of the vestibular nuclei.
