Amygdala

The amygdala is an almond-sized part of the brain, located in each hemisphere, that is best known for its role in emotional states. It is physically connected to the caudate nucleus of the basal ganglia, but is often considered to be a separate anatomical structure from the basal ganglia. It is located close to the medial temporal lobe and the hippocampus. It has been considered part of the limbic system.
