Debate needed over research with ‘potential for something to suffer’, neuroscientists say
Neuroscientists may have crossed an “ethical rubicon” by growing lumps of human brain in the lab, and in some cases transplanting the tissue into animals, researchers warn.
The creation of mini-brains or brain “organoids” has become one of the hottest fields in modern neuroscience. The blobs of tissue are made from stem cells and, while they are only the size of a pea, some have developed spontaneous brain waves, similar to those seen in premature babies.
