Chapter Abstract (Approx 50-100 words): The emotion system includes several interacting circuits that also form part of the sensory, motor, and autonomic systems. Emotion is an ancestral brain state that is critical for survival. Emotion is both a psychological and physical reaction, experienced as a strong feeling associated with physiologic changes that prepare the body for immediate action. Disorders of the emotion system underlie a wide range of neurologic, psychiatric, and medical conditions. These include chronic pain disorders, drug addiction, anxiety, depression, and metabolic syndrome.
