The limbic system (or paleomammalian brain) is a system deep within the brain that is implicated in humans’ abilities in relationships and attachments.

It is a complex set of brain structures that lies on both sides of the thalamus, right under the cerebrum. It is not a separate system, but a collection of structures from the telencephalon, diencephalon, and mesencephalon.

The limbic system includes the hippocampus, amygdala, anterior thalamic nuclei, septum, habenula, limbic cortex and fornix.
It supports a variety of functions, including emotion, behaviour, motivation, long-term memory, and olfaction (smell and taste) It appears to be primarily responsible for our emotional life, and has a great deal to do with the formation of memories (also see trauma memory page).
