Some call it your sixth sense. You refer to it when you have a “gut feeling.” With a vast fiber network running throughout your body, the vagus nerve knows about and helps regulate every critical function in it, from heart rate to digestion to your immune system. Now bioelectric medicine is tapping into that bodily omniscience by using tiny electrical pulses on the vagus nerve to help treat diseases as diverse as epilepsy, diabetes, stroke, Parkinson’s, and even depression. In the coming months, the FDA is set to make a decision about a vagus nerve stimulation device, which, if approved, could provide first-of-its-kind treatment for an autoimmune disease that affects millions of Americans. We consider the groundbreaking potential of vagus nerve stimulation and ask whether electricity could one day replace medications.
