The fastigial nuclei is situated atop the roof of the fourth ventricle (thence its name: "fastigus" is Latin for "summit"). [1]The fastigial nucleus is a mass of gray matter nearest to the middle line at the anterior end of the superior vermis, immediately over the roof of the fourth ventricle (the peak of which is called the fastigium), from which it is separated by a thin layer of white matter.
There are four paired deep cerebellar nuclei embedded in the white matter centre of the cerebellum. The nuclei are the fastigial , globose , emboliform , and dentate nuclei. In lower mammals the emboliform nucleus appears to be continuous with the globose nucleus, and these are known together as the interposed nucleus .
It is located dorsal to the fourth ventricle and lateral to the fastigial nucleus; it receives afferent neuronal supply from the anterior lobe of the cerebellum and sends output via the superior cerebellar peduncle and the red nucleus. [8] The fastigial nucleus is the most medial efferent cerebellar nucleus, targeting the pontine and medullary ...
It sends fibres to deep cerebellar nuclei (including the fastigial nucleus) which in turn project to both the cerebral cortex (via midbrain and thalamus) and the brain stem (via reticular formation in the pons, and vestibular nuclei in the medulla oblongata), thus providing modulation of descending motor systems. The spinocerebellum contains ...

Therefore, the fourth ventricle is the connector between the ventricular system (where CSF is produced) and the subarachnoid space (where CSF is absorbed). The roof rises (i.e. posteriorly) to a peak, known as the fastigium (Latin for "summit"); [1] the fastigial nucleus lies immediately above the roof of the fourth ventricle, in the cerebellum ...
The vestibulocerebellar tract fibers are second-order fibers from the vestibular nuclei, and first-order fibers from the vestibular ganglion/nerve. [1] They pass through the juxtarestiform body of the inferior cerebellar peduncle to reach the cerebellum, [1] They terminate in the vestibulocerebellum, and part of the vermis as well as the dentate nucleus, and fastigial nucleus in each ...
Most vertebrate species have a cerebellum and one or more cerebellum-like structures, brain areas that resemble the cerebellum in terms of cytoarchitecture and neurochemistry. [81] The only cerebellum-like structure found in mammals is the dorsal cochlear nucleus (DCN), one of the two primary sensory nuclei that receive input directly from the ...
