Italian doctors perform a head-changing operation on mice

According to the British "Independent" reported on the 1st, the team of Italy's highly controversial neurosurgeon Sergio Canavero has recently performed a head transplant on the rats. Canavelo plans to carry out a human head transplant at the end of the year, but has been criticized by some well-known experts.

Three rats were involved in the operation. Scientists connected the head of a small mouse to the body of another large mouse to create a "double-headed" animal; then used a pump to make the third Only the rats were transfused to the transplanted head to ensure that the brain was not deprived of oxygen.

The latest research, published in the journal Central Neuroscience and Therapeutics, is based on the study of problems related to blood flow to the brain and the rejection of new organs by the immune system – these problems may also occur during human transplantation.

Canavelo plans to perform a head transplant on humans by the end of this year. He had previously announced that the patient who underwent surgery at that time might be the Russian Valery Sbilidov, who was born with a rare genetic disease of spinal muscular atrophy, but later said that he was the first to undergo a head transplant. It is very likely that a person is a Chinese. The right and wrong of this change is still unclear.

Previously, Canavelo and his collaborator, Ren Xiaoping of Harbin Medical University, had conducted a series of experiments related to head transplantation. Their method involves cutting the spinal cord with a very sharp knife and then placing the body in a cold state to heal.
