The vagus nerve, which is the body's longest nerve, originates from the brain. It consists of approximately 80,000 nerve threads, and controls pulses to and from the gastrointestinal tract, the heart, the lungs and the spleen.
It has been shown that the immune system is attenuated when the vagus nerve is stimulated with electrical impulses. This means that inflammation can be suppressed by stimulation of the nerve, and it is therefore called the anti-inflammatory reflex.
Patients with rheumatoid arthritis have successfully been treated by stimulation of the vagus nerve. The treatment method is relatively new, and there are great hopes to treat various inflammatory diseases with it in the future.
