Facilitatory signals arrive through the ventral reticulospinal tract from Brodmann area 4, the neocerebellum and the vestibular nucleus.
2.
Another pathway ( not in picture ) directly projects from the vestibular nucleus through the ascending tract of Dieters to the ipsilateral medial rectus motoneuron.
3.
Axons of the vestibular nerve synapse in the vestibular nucleus are found on the lateral floor and wall of the fourth ventricle in the pons and medulla.
4.
:The medial vestibulospinal tract projects bilaterally from the medial vestibular nucleus within the medial longitudinal fasciculus to the ventral horns in the upper cervical cord ( C6 vertebra ).
5.
Lateral vestibulo-spinal tract ( lateral vestibular nucleus Deiters )-via ventrolateral medulla and spinal cord to ventral funiculus ( lumbo-sacral segments ) . . . Ipsilaterally for posture
6.
Fibres from the lateral vestibular nucleus also pass via the vestibulospinal tract, to anterior horn cells at many levels in the spinal cord, in order to co-ordinate head and trunk movements.
7.
In 1863 a German anatomist Otto Friedrich Karl Deiters described the existence of an unbranched tubular process ( the axon ) extending from some cells in the central nervous system, specifically from the lateral vestibular nucleus.
8.
His name is lent to the " nucleus of Deiters ", also called the lateral vestibular nucleus, and to " Deiters'cells ", structures that are associated with outer hair cells in the cochlea of the inner ear.
9.
His name is lent to several other anatomical structures, including " Schwalbe's nucleus " or the vestibular nucleus; " Schwalbe's ring ", which is a circular ridge consisting of collagenous fibers surrounding the outer margin of Descemet's membrane; and " Schwalbe's line ", an anatomical line located on the posterior surface of the eye's cornea.
