Seven months to go and the world's first human head transplant will be performed. However, the contradicting bodies warn that it should not be taken seriously.

On part of science, the world's first human head transplant is a great opportunity and breakthrough if it becomes successful. However, Brain Decoder reported that Sergio Canavero's plans to conduct the entire operation are absurd as perceived by other physicians, neurosurgeons, and bioethicists.

For them, Canavero is a total "nuts" and the operation he proposed is "worse than death." Recently, according to Wired, Canavero and Chinese surgeon Xiao-Ping Ren claimed to successfully transplant a head of a rat onto other rat's body. Tough the procedure was praised as a step for the world's first human head transplant, neuroscientists wary of the claims.

Neuroscientist Dean Burnett from Cardiff University said that it's vital to keep the organs intact and alive during the procedure and any approach to do this will be greatly valued by science. But, the previous experiment of head transplant conducted on the rats showed that keeping the severed head alive was not shown clearly.

Paul Zachary Myers, a professor of Biology from the University of Minnesota Morris stated his opinion on the coming procedure of the world's first human head transplant. "It's a pointless exercise in microsurgical technique," he said.

Lots of surgeons see nerve regeneration as the main issue in performing the operation for the head transplant. They explained that the ability of the central nervous system to regenerate neurons is the main source of survival and failing to do this can lead to death.

"The human nerve is not going to regenerate well enough for long term survivability," Dr. Gordon Lee the director and plastic surgeon at Stanford Health Care explains. Additionally, the world's first human head transplant procedure should pass any ethics board that supplies the argument caused by the head transplant on the rats.

Many surgeons insist that alarm bells should be ringing if a claim does not provide a robust scientific evidence. But, now, their group are encouraging the public not to take the world's first human head transplant seriously for its just a "science fiction."
