Answer 1

Previously, everybody believed that the brain had nothing to do with the immune system [the body's response to illness]. But Kevin Tracey, MD has shown that this is not correct. The brain actually controls inflammation, which is the body's response to infections as well as to autoimmune disease. [In autoimmune disease, the body causes its own illness. In infection, germs or viruses cause the illness.]
Kevin Tracey, MD is going to give a lecture and explain the experiments he performed. He will show that by stimulating the vagus nerve, excessive inflammation can be stopped and lives can be saved. Sepsis, or severe infection of the whole body, can cause an overwhelming inflammation. This excessive inflammation can kill the person. By understanding how the vagus nerve controls inflammation, we may be able to use the body's own healing powers to calm the inflammation before it kills its victim. Every year many people suffer from sepsis, and many of them die because doctors cannot cure them.
The vagus nerve starts in the brain stem, and travels down through the heart and down through the abdomen. Dr Tracey and others are studying how it works.
Dr Tracy is a neurosurgeon who got interested in research because of the death of a patient of his, a girl who died from being accidentally burned with hot water. He wondered why the body can make its own cells do harm to itself. He discovered that the vagus nerve directly controls the immune system through a chemical called acetylcholine. He was surprised to find that stimulating the vagus nerve can shut down the production of harmful chemicals in the body. He calls this process the "inflammatory reflex."
They are now studying to see whether they can control the brain's acetylcholine production to help autoimmune diseases like Crohn's disease, arthritis, and Alzheimer's disease.
Dr. Tracey has presented his work to the Dalai Lama, who is very interested in neuro-science, and he has written a book called "Fatal Sequence," about how the immune system helps and harms the body.
