This page covers biological details of component Medial Vestibular Nucleus. Region is part of aHuman target integrated biological model.

• Top-down path to region: Hindbrain Metencephalon -> Vestibular Nuclei (LPC.HT.VBN) -> Medial Vestibular Nucleus (LPC.HT.MVBN) (see Mind Maps)
• Type: nucleus
• Brain area: Lower Brain - Peripheral Control Area
• Role: sensory.nucleus
• Function: controlling head position, integrate head and eye movements; maintain balance, coordinating postural adjustments; coordination for horizontal eye movements
• Notes to function: to thoracic, bilateral - medial vestibulospinal tract in MLF; to CR; to oculomotor, trochlear, abducens, accessory oculomotor
