As quoted in the article "Drug Free Remedies for Chronic Pain", featured in AARP Magazine: "While acute pain appears in areas of the brain that are connected to tissue damage, chronic pain lives in other areas of the brain - the prefrontal cortex and limbic system. Which the brain uses for memories, especially emotional ones. In some cases the pain lives on long past the time when the body tissues have healed. Repeated thoughts and emotions create nerve pathways in the brain. Chronic pain impulses travel along well-worn pathways. By using techniques such as guided imagery to build new nerve pathways, the pain pathways can become less active and dominant."
