Basal ganglia. The basal ganglia (or basal nuclei) is a group of subcortical nuclei, of varied origin, in the brains of vertebrates including humans, which are situated at the base of the forebrain. Basal ganglia nuclei are strongly interconnected with the cerebral cortex, thalamus, and brainstem, as well as several other brain areas.
In addition it shows the internal capsule and its important role in carrying axons of the corticospinal tract. The diagram opposite also shows the Lentiform nucleus (striatum) of the Basal Ganglia in cross section; this part of the basal ganglia also has important connections with the cortex and the thalamus.
