"Miniature "human brains" have been grown in a lab in a feat scientists hope will transform the understanding of neurological disorders.
The pea-sized structures reached the same level of development as in a nine-week-old foetus, but are incapable of thought.
The study, published in the journal Nature, has already been used to gain insight into rare diseases.
Neuroscientists have described the findings as astounding and fascinating."
Amazing! As one of the researchers said: "Any technique that gives us 'something like a brain' that we can modify, work on, and watch as it develops, just has to be exciting."
