Head to Head - Part 2

Meet the modern-day Dr Frankenstein who is about to carry out the most radical surgery ever – transplanting a human head. Flamboyant Italian physician Professor Sergio Canavero says he has now perfected the techniques required to perform this previously impossible surgery. The doctor says it will allow the severely disabled to walk again by having their heads transplanted onto healthy bodies. Some say he’s a madman, others believe he’s a genius. And as Matt Doran reports, he now has a patient willing to put his life on the line in the name of science.
