The vestibulospinal tract originates from cells of the lateral vestibular nucleus, which lies in the floor of the fourth ventricle. Fibres of this tract descend the length of the spinal cord in the ventral and lateral funiculi without crossing, enter laminae VIII and… Read More Function: Lateral vestibulospinal tract is excitatory to the spinal motor neurons which supply extensor muscles of neck, back and limbs. It is inhibitory to neurons which supply flexor muscles of limbs. Medial vestibulospinal tract inhibit spinal motor neurons which supply muscles of neck and upper part of back.

Effects from the vestibulospinal tract on transmission from primary afferents to ventral spino-cerebellar tract neurones. Baldissera F, Roberts WJ. Convergence of vestibulospinal and segmental effects onto spinal interneurones which project to the ventral spino-cerebellar tract (VSCT) neurones has been studied by intracellular recording in VSCT cells.

The AlterG can reduce the weightbearing of patients and hence can facilitate their locomotion. Three children with cerebral palsy (CP) received AlterG training three days per week for eight weeks with each session lasting 45 minutes. The lateral vestibulospinal tract is one of the descending spinal tracts of the ventromedial funiculus.. The lateral part of the vestibulospinal tract is the major portion and is composed of fibers originating in the lateral, superior, and inferior vestibular nuclei (primarily the lateral). It projects ipsilaterally down to the lumbar region of the spinal cord. The medial vestibulospinal tract, however, arises from the medial vestibular nucleus and descends within the medial longitudinal fasciculus of the brainstem. The length of these two vestibulospinal tracts differs, with the lateral vestibulospinal tract descending along the entire spinal cord, while the medial vestibulospinal tract stops at the mid-thoracic.
The vestibulospinal tracts do not decussate. There are two vestibulospinal tracts that control anti-gravity muscles via LMNs: Medial vestibulospinal tract: originates in the medial vestibular nucleus, to control ipsilateral postural and tone adjustments in response to the vestibular apparatus. The cells of origin of the lateral vestibulospinal tract lie in the lateral vestibular nucleus. Axons arising from this nucleus descend through the caudal brain stem (you don't see these fibers on the cross sections) and upon reaching the spinal cord course within the ventral funiculus and innervate neurons for the ENTIRE length of the cord.

Hongo T, Kudo N, Tanaka R. Effects produced by stimulation of Deiters' nucleus on contralateral hindlimb motoneurones were investigated in the cat with intracellular and monosynaptic reflex recording. vestibulospinal pathways & functions mono- and poly-synaptic input to motor neurons of both extensor and flexor muscles LATERAL VESTIBULOSPINAL TRACT (LVST) Vestibulospinal Tracts. There are two vestibulospinal pathways; medial and lateral. They arise from the vestibular nuclei, which receive input from the organs of balance. The tracts convey this balance information to the spinal cord, where it remains ipsilateral. The main descending tracts are the lateral vestibulospinal tract from the lateral vestibular nucleus and the medial vestibulospinal tract from the medial vestibular nucleus. The lateral vestibular tract starts in the lateral vestibular nucleus and descends the length of the spinal cord on the same side.
