However, there have been many critiques by other medical experts of the significance or relevance of experimental research cited in the proposed protocol for human head transplantation, as surgical precedents set in animals are not always applicable to human surgery. Many of the planned tools and techniques, such as spinal cord transection, chemical fusogens (agents that allow cells to fuse together), and spinal cord stimulation have not yet been well studied for their relevant use in human head transplantation. Xiaoping Ren and Sergio Canavero said thenew work they published in a scientific journal showed that monkeys and dogs were able to walk again after their spinal cords were "fully transected"during surgery and then put back together again.
