Patients with amputated or lost limbs may experience phantom limb pain, and one doctor explains how the brain still connects to a body part that is no longer there.

John J. Miller discusses phantom limb pain and examples found in The Tell-Tale Brain: A Neuroscientist's Quest for What Makes Us Human by VS Ramachandran.

Dr Miller is Medical Director, Brain Health, Exeter, NH; Editor in Chief, Psychiatric Times; Staff Psychiatrist, Seacoast Mental Health Center, Exeter, NH; Consulting Psychiatrist, Exeter Hospital, Exeter, NH; Consulting Psychiatrist, Insight Meditation Society, Barre, MA.
