The '''fastigial nucleus''' or '''nucleus fastigii''' refers specifically to the concentration of gray matter nearest to the middle line at the anterior end of the superior [[vermis]], and immediately over the roof of the [[fourth ventricle]], from which it is separated by a thin layer of white matter.<ref>{{cite web|url=http://www.neuroanatomy.wisc.edu/cere/text/P5/S/C50.htm|title=The Global Cerebellum '97|author=John K. Harting, Ph.D.|publisher=University of Wisconsin Medical School|year=1997|accessdate=2007-06-28}}</ref> It is smaller than the [[nucleus dentatus]], but somewhat larger than the [[nucleus emboliformis]] and [[nucleus globosus]], the other two independent centers of gray matter in the [[cerebellum]].
==Relations and function==
The fastigial nucleus receives its afferent input from the [[flocculonodular lobe]] and the [[vermis]]. Most of its efferent connections travel via the [[inferior cerebellar peduncle]] to the [[vestibular nuclei]], which is located at the junction of the [[pons]] and [[medulla]].
The fastigial nucleus deals with antigravity muscle groups and other synergies involved with standing and walking.<ref>{{cite book|title=Neurology for the Boards|author=James D. Geyer, Janice M. Keating, Daniel C. Potts|publisher=Lippincott-Raven|year=1998|city=Philadelphia|pages=9}}</ref>
