They are situated at the base of the forebrain and are strongly connected with the cerebral cortex, thalamus and other brain areas.
Basal nuclei: A region located at the base of the brain composed of 4 clusters of neurons, or nerve cells. This area of the brain is responsible for body movement and coordination.The groups of neurons most prominently and consistently affected in Huntington disease -- the pallidum and striatum -- are located in the basal nuclei.The pallidum is composed of structures called the globus pallidus and the ventral pallidum while the striatum consists of the caudate nucleus, putamen, and ventral striatum.). The basal nuclei are also called the basal ganglia.
