Italian doctors prove that a head transplant surgery can be successful

Dr. Sergio Canavero confirms the success of treating paralyzed animals can prove the feasibility of head implant surgery.

Sergio Canavero , an Italian neurosurgeon who aspires to make the world's first transplant next year, offers a series of videos showing paralyzed animals treated with his breakthrough technique, According to Sky News.

The video filmed a mouse and a dog can walk normally. A few weeks ago, their spinal cord was cut off and chemically treated to get together. The experiment was conducted by Korean researchers in collaboration with Dr. Canavero. Canavero emphasized that these experiments demonstrated that the spinal cord could be restored, paving the way for head implant surgery on paralyzed patients.

The Korean team published their experimental details in a series of articles in the journal Surgical Neurology International on September 13, in which Dr. Canavero plays a compilation role. In the first experiment, the spinal cord of 16 mice was cut off. Half of the mice were injected with polyethylene glycol (PEG) compound between the severed nerves. The other half is injected with saline solution.

5 PEG-treated mice have the ability to move, indicating the chemical that helps to connect the cut nerve, allowing the signal from the brain to continue to transmit to the limbs.

In the second experiment, PEG was combined with extremely small graphene fibers that acted as a pathway to ensure that the two ends of the spinal cord grow toward each other. A mouse that uses this method can walk again after two weeks.

In the last experiment, a dog had a broken spinal cord up to 90% due to injury similar to the person who was stabbed in the neck treated with PEG. Three days later, the dog can move slightly. After three weeks, he can walk and wave his tail.

However, many other scientists were skeptical and judged that the number of treated animals was too small, providing insufficient evidence of the feasibility of head implant surgery."These reports do not prove the possibility of success in humans. The dog in the video does not have a body transplant, but only the spinal cord is cut off and restored." New Scientist quoted the god scientist.
