But experts believe the electrical current might help activate nerve cells that are not working correctly.

In MS the damage to myelin exposes channels on the surface of the axon, allowing potassium ions to leak out and thus dissipate the electrical current that carries nerve signals.
"The Road" was originally set to come out last year, and in one sense the decision to delay its release was karmically right, since (like " 2012") it addresses the current mood of nerve-jangling anxiety and doom.
Each segment has an electromagnet attached to it, and these are activated by a current that flows from head to tail in more or less the way that a nerve signal flows in a real animal.
