'Master Gene' Makes Mouse Brain Look More Human 121
sciencehabit writes "Researchers have found a genetic mutation that causes mammalian neural tissue to expand and fold. When they mutated this gene in mice, the rodents developed brains that look more like ours (abstract). The discovery may help explain why humans evolved more elaborate brains than mice, and it could suggest ways to treat disorders such as autism and epilepsy that arise from abnormal neural development. The findings go against a common conception that 'dumber species will have different genes' for brain development than more intelligent species, Borrell says. He adds that the mechanism could help explain how New World monkeys, with their small, smooth brains, could have evolved from an ancestor with a bigger and more folded brain."
Disappointed. (Score:5, Funny)
I was somehow hoping this study was done at NIMH.
