Description Your health and happiness depend on a bundle of 200,000 nerve fibres that holds the secrets to life itself ‘The Great Nerve is altogether a masterpiece and a timeless document for those who want to see what science is all about: faith, focus, patience and hard work’ Wim Hof, bestselling author of The Wim Hof Method The vagus nerve is often referred to as the ‘superhighway’ which connects every organ of the body to the brain, and vice versa, but it is so much more than just traffic. The ‘great nerve’ vibrates in tune with your health like the instruments of an orchestra: when your vagus nerve is healthy, so are you. When it isn’t, you experience everything from poor sleep to low mood, pain, suffering and chronic illness. Recent scientific developments, including Dr Kevin Tracey’s research showing how the vagus nerve is linked to the immune system, have brought the nerve to the attention of everyone from neuroscientists to TikTok influencers. About the Author Dr Kevin Tracey is a neurosurgeon, scientist, entrepreneur, and leader in the fields of inflammation and vagus nerve stimulation. Along with his colleagues in his lab at the Feinstein Institutes, Dr. Tracey discovered the molecular and neural mechanism for the reflexive control of inflammation, now termed the inflammatory reflex. He is a prolific inventor with more than 120 U.S. patents. As measured by and reported in the scientific journal PLOS One, Dr. Tracey is one of the most highly cited living scientists in the world.
