The first human head transplant is expected to take place in December this year and will be performed by Italian neurosurgeon Sergio Canavero.
Canavero has been planning this for 30 years, so he hopes everything will go best.
This transplant will be performed in Russian patient Valery Spiridonov, who suffers from a rare form of spinal muscular atrophy.
The operation will include cooling the time to -15 degrees Celsius and placing that head on a dead brain's body. The spinal cord nerves from the patient and those of the body where the head will be placed are expected to bind with the aid of polyethylene glycol.
The intervention is expected to cost around $ 11 million and will last 36 hours.
