Vestibulospinal Tract - Viktor`s Notes for the Neurosurgery Resident
... The vestibulospinal tract arises from the lateral vestibular nucleus (Deiters nucleus) and descends ipsilaterally in the lateral funiculus of the spinal cord. Vestibulospinal neurons synapse in laminae VII, VIII, and IX of the spinal cord. Several vestibulospinal fibers synapse directly with α and ϒ ...
