Signal flow from the balance organ to the cerebellum.

The signals travel in primary vestibular moss filaments which exit from the balance organ itself through the vestibularis nerve and into the brainstem to the vestibularis nuclei where lateral branches are emitted to the upper, inner and lower vestibularis nuclei. The stem threads continue into the cerebellum through the lower cerebellar arm and contact barley cells in the nodulus cerebelli as well as in the posterior and anterior parts of the corpus cerebellis vermisparti.
