Caption: Researchers have shown how an experimental drug might restore the function of nerves damaged in spinal cord injuries by preventing short circuits caused when tiny "potassium channels" in the fibers are exposed by trauma. The compound also might be developed as a treatment for multiple sclerosis. This diagram illustrates how the drug functions as a "channel blocker," meaning it permits the conduction of signals even though the protective myelin insulation has been damaged.
