Scientists are implanting tiny HUMAN brains into rats
Stanford University bioethicist says as the lab rats become more human-like they may one day be 'entitled to some kind of respect'
Advances in science have allowed experts to connect tiny human brains with that of a rat. To do this, they created clumps of cells that behave similarly to human brains called organoids.Several labs have inserted those organoids into rat brains, connected them to blood vessels and successfully grown physical links.
Medical mag Stat reported that when scientists shone a light into a rat's eye or stimulated the brain regions involved in vision, that the neurons in the implanted organoid fired up.
It said: "That suggested the human brain tissue had become functionally integrated with the rat."
Scientists hope this will help us understand brain injuries or treat disease. But experts warn that the more human brain we implant into rats, the more human-like they will become.
Labs are implanting around three or four organoids in rats for now, but what if they added more? (Read More)
