The Vagus Nerve and nVNS

In 2010, after years of research our scientific experts developed the ability to stimulate the vagus nerve without the need for surgery, which had never been done before. By using gammaCore’s nVNS technology, users now have an alternative method to stimulate the vagus nerve and reduce headache pain through proprietary gentle electrical stimulation through the skin on either the right and left side of the neck.

What is the Vagus Nerve?

It is the longest cranial nerve in the body, primarily serving as a sensory nerve, bringing information from the visceral organs to the brain. The vagus nerve has a number of branching nerves that go to the heart, lungs, voice box, stomach, ears, and other organs. As a sensory nerve that assesses the condition of these organs, it is the communication between the brain and the body. It contains motor and sensory fibers and, because it passes through the neck and thorax to the abdomen, has the widest distribution in the body.

What Happens When nVNS is Used?

Stimulating the vagus nerve affects many important autonomic functions in the brain and in the body, including neurotransmitter levels, inflammation levels, and metabolism. Ultimately it effects pain signals, reducing acute headache episodes; helping to manage pain.
