Research Evaluating Vagal Excitation and Anatomical Links
We are studying the effects of stimulating the vagus nerve. The vagus nerve connects the brain to many organs in the body. Vagus nerve stimulation (VNS) is already approved by the United States Food and Drug Administration (FDA) to treat depression and epilepsy. We want to learn more about how it affects other parts of our bodies, such as the heart, metabolism, the immune system, and the nervous system. We hope that by understanding how VNS affects the body as a whole, we can develop new treatments for other conditions, or help to improve its use for depression and epilepsy.
