According to Michael Gershon, M.D., author of The Second Brain (HarperCollins, 1999), and a neurobiologist at New York's Columbia-Presbyterian Medical Center. Gershon recently explained to PT how an independent network of over 100 billion neurons in the gut not only signals our bodies to stress but causes illness.
