Remember the old ad campaign, "What happens in Vegas stays in Vegas"? It takes on a whole new meaning when considered in light of the body's neural superhighway, the vagus nerve.

In this presentation, Leah Welborn briefly outlines the function of the vagus nerve and discusses some of the unpleasant side effects we experience when it's unregulated.
