LONDON, Sept 6: Scientists have grown the first mini human brains in a laboratory and say their success could lead to new levels of understanding about the way brains develop and what goes wrong in disorders like schizophrenia and autism. Researchers based in Austria started with human stem cells and created a culture in the lab that allowed them to grow into so-called “cerebral organoids” – or mini brains – that consisted of several distinct brain regions.
