The body of marathon runners perceives and consumes their brain tissue as a source of energy 

A new study by scientists shows that the body of marathon runners uses part of their brain tissue to consume energy. Brain scans of these runners after the race show that the myelin tissue around the brain nerves has thinned.

According to Tekna technology and technology news service , according to the researchers, brain fat around the nerve fibers is greatly reduced during the competition and returns to its normal level two weeks later. It seems that the body of runners uses this fat tissue for energy during the race.

In another study, the brains of four marathon runners were examined using MRI before and after the race. In this scan, the researchers saw a decrease in the amount of myelin in the brain 1-2 days after the competition. Myelin is present in a large part of the human brain and covers the nerve fibers and acts as an insulator for them like a rubber around an electric wire. Myelin, with its dynamic structure, has the property of plasticity, and for this reason, it is able to grow and increase or decrease in size according to cell conditions.
