How gammaCore (nVNS) Works

gammacore UK

gammaCore activates the vagus nerve with patented, gentle electrical stimulation.


Non-invasive vagus nerve stimulation with gammaCore helps block the pain signals that cause migraines and cluster attacks.


Unlike traditional vagus nerve stimulation therapies, gammaCore stimulates the nerve non-invasively through the skin without the need for surgery.
