medial vestibular nucleus

The medial vestibular nucleus is one of the vestibular nuclei.

The medial vestibulospinal tract originates in the medial vestibular nucleus or Schwalbe's nucleus.

The medial part of the vestibulospinal tract is the smaller part, and is primarily made of fibers from the medial vestibular nucleus.

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).

Gamma-Aminobutyric acid (GABA) is thought to be inhibitory for the commissures of the medial vestibular nucleus, the connections between the cerebellar Purkinje cells, and the lateral vestibular nucleus, and the vertical VOR.

The first and third zones of the flocculus project to the superior vestibular nuecleus, the second and fourth zone projects to the medial vestibular nucleus, and the fifth zone projects to the interposed posterior nucleus, a part of the cerebellum.
