Scientists have digitally recreated a slice of a juvenile rat's brain — including 31,000 brain cells, of 207 different types, with 37 million connections. The computer-simulated brain achievement is part of the Blue Brain Project, whose aim is to create a rat brain and, eventually, a human brain inside a computer.
