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

• 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

• 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}

The juxtarestiform body coordinates balance and eye movements by communication between the vestibular apparatus and the cerebellum.^{[citation needed]}
