How It Works

Unlike traditional vagus nerve stimulation, gammaCore non-invasive vagus nerve stimulator (nVNS) activates the vagus nerve with gentle electrical stimulation through the skin to prevent and relieve headache pain, without the need for surgery.

Why simulate the vagus nerve? Think of the vagus nerve as the “superhighway” of the nervous system. This important highway sends communications between your brain and many parts of the body.

Stimulating the vagus nerve blocks the pain signals causing the attacks, to help provide fast relief and prevent future attacks.
