Is it genuinely a body accompanied by a new head or a head with an alternative body?

Scientists and doctors have already thought about and tried to transplant heads in different animals, but without success. In Gemini magazine, Prof. Canavero said about a planned future head transplant that will be successful. Now, he plans to take a donor head that is not suitable for normal use, and that is intended to be a material for a healthy body and transplant to a person who has maintained normal brain function, but whose body is ineffective.
