A miniaturised "brain-in-a-bottle" has been grown by stem cell scientists who hope it will lead to new treatments for neurological and mental diseases.

But the scientists insist they are still far from the science fiction fantasy of building a working artificial brain - or even replacement parts for damaged brains.
