Basal nuclei


Deep within the white matter, there are specialized areas of gray matter within the cerebrum known as the basal nuclei. The corpus stratum is recognized as the most prominent and detectable of the basal nuclei.

The appearance of stripes gives the corpus stratum its name. Various areas of amassed nuclei make up the corpus stratum. The upper mass is known as the caudate nucleus.


The lentiform nucleus is created by the collective efforts of the white band of matter that is situated between the caudate nucleus and the subsequent two masses. The lentiform nucleus us created by the later and medical sections, known as the putamen and the globus pallidus, respectively.

The basal nuclei is comprised of an additional segment known as the claustrum. This thin strip of gray matter is positioned just beneath the cerebral cortex of the insula. Other brain structures, especially including the mesencephalon, have associations with the basal nuclei.

Actions such as involuntary arm movements while walking and other involuntary muscular motion is controlled in part by the basal nuclei of the caudate nucleus and the putamen. Voluntary muscular skeletal movements and the needed muscle tone for such action is controlled by the globus pallidus.

A vast number of the neural diseases or trauma to the brain can result is a variety of motor skill issues, including tremors, uncontrolled movements, dysfunctional movement, and rigidity.
