Under a microscope, the brain looks like a cutdown forest of many tree stumps with dark tree rings. The "rings" are , an insulation made of fat that wraps around nerves to help send faster electrical signals.Unfortunately, myelin is also the target of many diseases like (MS), which . In this disease, the immune system inexplicably attacks the body’s own myelin and the cells that produce it. As the now bare nerves die, cells can no longer reach the injured area to wrap new myelin around the damaged nerves., but the real question is how to insulate the nerves again? , scientists found that a...…Under a microscope, the brain looks like a cutdown forest of many tree stumps with dark tree rings.
