Neuroscientist thinks human head transplant surgery is finally possible

An Italian neuroscientist believes he's figured out how to do a full human head transplant. Or body transplant, depending on your perspective. In a recent paper, Dr. Sergio Canavero of the University of Turin explains how the procedure would work, describing how a "clean cut" with an "ultra-sharp blade" could leave the two severed spinal cords in the condition to be re-attached. "It is my contention that the technology only now exists for such linkage," writes the researcher.
