With a primordial structure, the limbic system is involved in lower order emotional processing of input from sensory systems and consists of the amygdaloid nuclear complex ( amygdala), mammillary bodies, stria medullaris, central gray and dorsal and ventral nuclei of Gudden. Emotional life is largely housed in the limbic system, and it critically aids the formation of memories. It supports a variety of functions including emotion, behavior, long-term memory, and olfaction.

The limbic system, also known as the paleomammalian cortex, is a set of brain structures located on both sides of the thalamus, immediately beneath the medial temporal lobe of the cerebrum primarily in the forebrain.
