Balance core, upper

Nucleus vestibularis superior

Bechterew's nucleus (vestbularis)

The core, a t.hay. and one t.v., located in the pons in the "floor" of the 4.de ventricle. The nucleus receives primary afferents from the nervus vestibularis, axons which mainly originate from the semicircular canals.
The vestibularis superior nucleus also receives signal flows from the cerebellum, spinal cord (tractus spino-vestibularis) and prepositus nucleus (formatio retikularis)

The nucleus vestibularis superior transmits axons:
1/ to the cerebellar cortex of the posterior (flocculus-nodulus) and anterior (lobus anterior cerebelli) parts of the vermispart,
2/ out in and up in the fasciculus longitudinalis medialis(FLM) and contacts via this conduction pathway the motor eye muscle nuclei with both crossed and uncrossed threads and the nuclei of Cajal and Darkschewitz.
3/ out in and up in the lateral limnique. These axons ascend towards the thalamus, cross the mean line and contact the VPL nucleus, a VPI nucleus connected to this (I = inferior) and the VL nucleus. These, in turn, relay the balance information to the lower part of the primary somato-sensory cortex as well as to an area of the sulcus interparietalis cortex and one becomes aware of the balance situation.
