Once a nerve cord is severed, for example after an accident, there is usually no cure. Only surgery can occasionally repair the damage. If at all. In some operations, nerve cords are removed from another part of the body and inserted at the point where it has been severed. This reconnects the nerve endings and enables that part of the body to recover its functionality, at least partially. If this is not possible, the limb or the whole body part remains paralyzed and rigid. Scientists at the Max Planck Institute for Polymer Research have now developed substances that stimulate damaged nerves to grow. Initial tests on mice have already shown that nerve cords can regenerate themselves this way.
