Freebase(0.00 / 0 votes)Rate this definition: Basal ganglia. The basal ganglia are a group of nuclei of varied origin in the brains of vertebrates that act as a cohesive functional unit. They are situated at the base of the forebrain and are strongly connected with the cerebral cortex, thalamus and other brain areas.
The extrapyramidal system consists of a series of functionally related nuclei in the telencephalon, diencephalon and midbrain. The basal ganglia represent the largest component, and include the caudate, putamen and globus pallidus. The pars reticulata and pars compacta of the substantia nigra of the midbrain as well as the subthalamic nucleus, which is located in the caudal diencephalon are functionally connected to this system.
