The '''lateral vestibular nucleus''' ('''Deiters's nucleus''') is the continuation upward and lateralward of the [[Principal sensory nucleus of trigeminal nerve|principal nucleus]], and in it terminate many of the ascending branches of the [[vestibular nerve]].
==Structure==
It consists of very large [[multipolar cells]] whose [[axons]] form an important part of the posterior longitudinal bundle (aka [[medial longitudinal fasciculus]]) of the same and the opposite side.
The axons bifurcate as they enter the posterior longitudinal bundle,
* the ''ascending branches'' send terminals and collaterals to the [[motor nuclei]] of the [[abducens]], [[trochlear nerve|trochlear]] and [[oculomotor nerve]]s via the ascending component of the [[medial longitudinal fasciculus]], and are concerned in coordinating the movements of the eyes with alterations in the position of the head;
* the ''descending branches'' pass down in the posterior longitudinal bundle into the [[anterior funiculus]] of the [[spinal cord]] as the [[vestibulospinal fasciculus]] ([[anterior marginal bundle]]) and are distributed to motor nuclei of the anterior column by terminals and collaterals.
Other fibers are said to pass directly to the vestibulospinal fasciculus without passing into the posterior longitudinal bundle.
The fibers which pass into the vestibulospinal fasciculus are intimately concerned with [[equilibratory]] reflexes.
Other axons from Deiters’s nucleus are supposed to cross and ascend in the opposite medial lemniscus to the ventro-lateral nuclei of the [[thalamus]]; still other fibers pass into the cerebellum with the inferior peduncle and are distributed to the cortex of the vermis and the roof nuclei of the cerebellum; according to Cajal they merely pass through the [[nucleus fastigii]] on their way to the cortex of the [[vermis]] and the hemisphere.
==History==
===Eponym===
Deiter's nucleus was named after German [[neuroanatomist]] [[Otto Friedrich Karl Deiters]] (1834–1863).
