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. [1]
The human cerebellum is located at the base of the brain, with the large mass of the cerebrum above it, and the portion of the brainstem called the pons in front of it. It is separated from the overlying cerebrum by a layer of tough dura mater called the cerebellar tentorium; all of its connections with other parts of the brain travel through the pons.
The fastigial nucleus (roof nucleus-1) is located in each cerebellar hemisphere. It is one of the four paired deep cerebellar nuclei of the cerebellum . It is made up of two sections: the rostral fastigial nucleus and the caudal fastigial nucleus.
The eight cerebellar nuclei, located within the deep white matter of each cerebellar hemisphere, are grouped into pairs, with one of each pair in each of the two hemispheres. As a chunk of tissue, the dentate nucleus with overlying cerebellar cortex makes up a functional unit called the cerebrocerebellum. Thus, there is a part of cerebellum ...
Sagittal cross-section of human cerebellum, showing the dentate nucleus, as well as the pons and inferior olivary nucleus. The deep nuclei of the cerebellum are clusters of gray matter lying within the white matter at the core of the cerebellum. They are, with the minor exception of the nearby vestibular nuclei, the sole sources of output from ...
It brings sensory and motor information to and from the cerebellum. The arbor vitae is located deep in the cerebellum. Situated within the arbor vitae are the deep cerebellar nuclei; the dentate, globose, emboliform and the fastigial nuclei. These four different structures lead to the efferent projections of the cerebellum. [2]
The emboliform nucleus is a deep cerebellar nucleus that lies immediately to the medial side of the dentate nucleus, partly covering its hilum. It is one of the four pairs of deep cerebellar nuclei, which are from lateral to medial: the dentate, emboliform, globose and fastigial. These nuclei can be seen using Weigert's elastic stain.
The globose nucleus is one of the deep cerebellar nuclei. It is located medial to the emboliform nucleus , and lateral to the fastigial nucleus . The globose nucleus and emboliform nucleus are known collectively as the interposed nuclei .
