Neurosurgeon Dr. Kevin Tracey is a founding father of bioelectronic medicine, and his discoveries about the vagus nerve are rewriting how we treat chronic disease. Dr. Tracey explains--in plain language--how a single nerve connects the brain to the immune system, why inflammation underlies so much suffering, and the everyday practices that can help you harness its healing power.
