The juxtarestiform body contains mostly cerebellar afferents, but also some cerebellar efferents.<ref name="Patestas-2016" />{{Rp|page=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).<ref name="Patestas-2016" />{{Rp|page=293}} The fibers project to the vestibulocerebellum and cerebellar vermis (of the spinocerebellum)<ref name="Patestas-2016" />{{Rp|page=290}} as well as to (ipsilateral and contralateral) fastigial and dentate nuclei.<ref name="Patestas-2016" />{{Rp|page=402}}

=== Efferents ===

* Cerebellovestibular fibers:<ref name="Patestas-2016" />{{Rp|page=290-291}} arise from Purkinje cells of the flocculonodular lobe of the cerebellum.<ref name="Patestas-2016" />{{Rp|page=297}} ** Fastigiovestibular fibers: mainly project to both ipsilateral and contralateral lateral and inferior vestibular nuclei to influence both vestibulospinal tracts.<ref name="Patestas-2016" />{{Rp|page=292}} ** Fastigiobulbar fibers: project bilaterally to the (medullary and pontine) reticular formation to influence both reticulospinal tracts (but mostly the contralateral one).<ref name="Patestas-2016" />{{Rp|page=292}} * Cerebelloreticular fibers<ref name="Patestas-2016" />{{Rp|page=290-291}}

==Function==

The juxtarestiform body coordinates balance and eye movements by communication between the vestibular apparatus and the cerebellum.{{Citation needed|date=July 2024}}
