The juxtarestiform body is the smaller, medial subdivision of each inferior cerebellar peduncle (the other, lateral one being the restiform body).[1]: 290
The juxtarestiform body contains mostly cerebellar afferents, but also some cerebellar efferents.[1]: 290
Anatomy
Afferents
- Vestibulocerebellar fibers: include second-order fibers from the vestibular nuclei (project bilaterally) as well as a few first-order fibers from the vestibular ganglion/nerve (project ipsilaterally).[1]: 293 The fibers project to the vestibulocerebellum and cerebellar vermis (of the spinocerebellum)[1]: 290 as well as to (ipsilateral and contralateral) fastigial and dentate nuclei.[1]: 402
Efferents
- Cerebellovestibular fibers:[1]: 290-291 arise from Purkinje cells of the flocculonodular lobe of the cerebellum.[1]: 297
- Fastigiovestibular fibers: mainly project to both ipsilateral and contralateral lateral and inferior vestibular nuclei to influence both vestibulospinal tracts.[1]: 292
- Fastigiobulbar fibers: project bilaterally to the (medullary and pontine) reticular formation to influence both reticulospinal tracts (but mostly the contralateral one).[1]: 292
- Cerebelloreticular fibers[1]: 290-291
Function
The juxtarestiform body coordinates balance and eye movements by communication between the vestibular apparatus and the cerebellum.[citation needed]
