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 .
This area produces Purkinje cells and deep cerebellar nuclear neurons. These cells are the primary output neurons of the cerebellar cortex and cerebellum. The second germinal zone (cellular birthplace) is known as the rhombic lip, neurons then move by human embryonic week 27 to the external granular layer. This layer of cells—found on the ...
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 ...
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 ...
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 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.
The inferior olivary nucleus (ION) is a structure found in the medulla oblongata underneath the superior olivary nucleus. [1] In vertebrates, the ION is known to coordinate signals from the spinal cord to the cerebellum to regulate motor coordination and learning. [ 2 ]
The Purkinje layer of the cerebellum, which contains the cell bodies of the Purkinje cells and Bergmann glia, express a large number of unique genes. [9] Purkinje-specific gene markers were also proposed by comparing the transcriptome of Purkinje-deficient mice with that of wild-type mice. [10]
