Are quadruplegics the same people, even if their body-image is going to the dogs? Are people with anaesthesized spinal cord still people or not? That's an experiment which is easy enough to try.

A hard validation would be a whole-head graft, which has been successfully done with animals. They attempted to vocalize/bite the experimenter (which is not very surprising -- I think in their place I'd try that, too). For some strange reason (duh), this has not been tried with people yet.

There are certainly individually distinct low-level motorics present in the spinal cord -- however, these can be learned or even convincing surrogates be installed in their place -- after all, ressurection does require nontrivial level of technology.
