Limbic system - Wikipedia
he 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.[1]
It supports a variety of functions including emotion, behavior, long-term memory, and olfaction.[2] Emotional life is largely housed in the limbic system, and it critically aids the formation of memories.
