Throughout the world more than 50,000 vagal nerve stimulators have been implanted. See the figure directly below. A pacemaker is placed inside the chest and an electrode is wrapped around the vagus nerve in the neck. This was originally done to treat seizures. In the thousands of seizure patients who had vagal nerve implants, many also reported relief of pain, others were cured of depression, still others spontaneously lost weight, some had their heart conditions reversed. These observations have opened the floodgates to research into the treatment of diverse conditions with vagal nerve implanted stimulators. The down side is who wants a stimulator implanted in their body? Now take a look at the bottom illustration. It exploits a branch of the vagus nerve in the ear to stimulate the vagus nerve without implanting a stimulator in the body. Recent fMRI studies suggest that the surface vagal nerve stimulator activates many of the same brain regions as the implanted device. A much better approach in our opinion.
Transcutaneous Vagal Nerve Stimulation or tVNS is producing a lot of excitement in
the research community. It safely and painlessly activates many diverse regions of
the brain. We’ve used it to treat chronic pain, help in stroke rehabilitation, and
to alleviate depression. It seems to have particular application for treatment of
fibromyalgia.
It’s simplicity and ease of application make tVNS an ideal technique
