They widened the gap (by removing a quarter inch of spine) to ensure that no nerve tissue remained to produce false-positive results. Then they built their cellular bridges according to a precise blueprint that carefully distinguished between the two kinds of nerve tissue in the spinal cord--white and gray matter. White matter contains the parts of nerves that are surrounded by a substance called myelin, which acts like insulation around an electric wire. Gray matter contains...
Using nerves from the rat's chest muscles for the bridge, Cheng carefully connected the insulated white matter on one side of the spinal cord to uninsulated gray matter on the other.
