This is an old story. How did I not hear about this before?
Infant rats are being decapitated and their heads grafted onto the thighs of adults by researchers in Japan.
If kept cool while the blood flow is stopped, a transplanted brain can develop as normal for at least three weeks, and the mouth of the head will move, as if it is trying to drink milk, the team reports.
The grafted heads could be “excellent models” for investigating brain function in human babies after periods of no blood flow, known as ischemia, they claim.
“Our main purpose is to investigate how the transplanted brain can develop and maintain function after prolonged total brain ischemia,” researcher Nobufumi Kawai, at the Jichi Medical School in Tochigi, told New Scientist. “And we tried to investigate the effect of lowering the temperature of the brain during the grafting.”
