One long-standing idea is that the amygdala consists of an evolutionarily primitive division associated with the olfactory system (cortical, medial and central nuclei) and an evolutionarily newer division associated with the neocortex (lateral, basal, and accessory basal nuclei).tructural and/or functional changes in the amygdala are associated with a wide variety of psychiatric conditions in humans. Included are various anxiety disorders (PTSD, phobia, and panic), depression, schizophrenia, and autism, to name a few.
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.
