Limbic System Paleomammalian brain

A complex set of brain structures that lies on both sides of the thalamus, right under the cerebrum.1. Collection of structures from the

telencephalon, diencephalon and mesencephalon .

2. Includes the hippocampus, amygdala, anterior thalamic nuclei, septum, habenula, limbic cortex and fornix.

3. Supports a variety of functions, including emotion, behavior, motivation and long term memory, and olfaction.

4. Primarily responsible for our emotional life.

5. Critical role in the formation of memories.
