It's a fascinating concept. You have an otherwise perfectly healthy head on a body that no longer functions. You have, also, an otherwise perfectly healthy donor body. What if you could take the head from its non-functioning body and transplant it onto the healthy body?
It seems like the stuff of science-fiction (and it has been), but it's not, perhaps, as impossible as it sounds. Take, for instance, the work of Russian transplant pioneer Vladimir Demikhov, who in the 1950s successfully transplanted dogs' heads onto the bodies of other dogs
