It's «an important technical advance,» said neuroscientist Michal Stachowiak of the State University of New York, Buffalo, who
created human cerebral organoids to study schizophrenia, and «an important initial step toward using organoids in regenerative medicine.»
But ever since
cerebral organoids were first
created from stem cells in 2013, they have ignited an intense ethical debate, including about whether they can suffer, feel pain, or be conscious — and whether they have
human rights.
