'Big Brain' Gene Found in Humans, Not Chimps.
New research suggests that a single gene may be responsible for the large number of neurons found uniquely in the human brain. When this gene was inserted in the brain of a mouse embryo (shown here), it induced the formation of many more neurons (stained red). The extra neurons led to the formation of characteristic convolutions that the human brain uses to pack so much brain tissue into a small space (convolutions shown on the right).
