Topics | Brain and Nervous System | Healthy Nervous System | Functions of Nerves | What does the vagus nerve do? The vagus nerve provides a speedy line of information to the brain from the gut, where battles with bacteria and viruses are continually raging. Knowledge of the vagus's role was a mystery until very recently, but we now know that you can learn about your body from your vagus. The longest nerve directly from the brain, the vagus sends messages to and receives messages from your gut and every other organ in your body. Because 85 percent of this huge nerve carries information back to the brain, it's the main mechanism by which your brain audits your body. The remaining 15 percent takes information from your brain to your body.
Vagal Nerve Stimulation. Vagal nerve stimulation is a treatment used to reduce the frequency and intensity of seizures when medications aren't effective. The vagus nerve is one of many nerves that carry messages to and from the brain. It helps regulate internal organs such as the heart and stomach. Nerve fibers within the vagus nerve are connected to the part of the brain believed to be responsible for producing seizures. This procedure involves placing a small electric stimulator in the neck around the vagus nerve and a power source near the armpit or chest.
