While, testing on nine rats with polyethylene glycol (PEG), eight alive a month after the operation, and they had regained the ability to walk.
Recently, a Chinese doctor conducted head transplants on more than 1,000 mice. However, those mice have lived longer than a few minutes.
Earlier this year, Italian neurosurgeon Sergio Canaverobelieve it’s possible and announced his plans to perform the first human head transplant.
Three years ago, he announced a human head transplant in a two modules, HEAVEN(head anastomosis venture) and GEMINI (subsequent spinal cord fusion).
He declares the schedule of first head transplant on 2017. He estimates the procedure of transplant to take 100 surgeons nearby 36 hours long journey to complete the process. The estimation of operation cost is $10million.

Combining a spinal cord has never done before, and may not possible. This is probably the main objection for people.
