I know that two heads are better than one, you all. I just didn't perceive it quite literally.
Another awfully creepy and amazing research of China!
Well, in a new study
published in CNS Neuroscience and Therapeutics, researchers successfully grafted smaller rats' head onto the necks of larger recipient rats.
You might wonder why do we keep on having such head transplant experiments?
These experiments actually became popular (as data suggest) due to the two-headed dog experiments of the early 1900s and 1950s followed by the two-headed monkey experiments of the 1970s, with each of the studies' results remaining to be unclear.
Now this time, such version of the experiment is some kind of a "preparation" for the future. Thing is, when human head transplants actually become a thing, one issue would be the possible brain-damaging blood loss during the process (while the donor head is being attached to the recipient). And this new test could shed light on how to address this problem.
In the experiment, the researchers attached the blood vessels of the donor rat's head to the blood vessels of a third rat (Guess three heads are better than two then, but it's just me. You can ignore this). This is to keep blood flowing continuously to the donor rat's brain. So, once the donor rat's head were fixed on the recipient rat's body, the donor's blood vessels are then transferred and attached to the recipient's.
And here it is- a two-headed rat! Great news?
Apparently, a scientist who's not affiliated with the said study is actually currently working towards the first human head transplant
. So I guess all of these are just for kicks and all.
