Neuroscientist Ed Lein reported an astonishing development in brain mapping in Nature. Through developing a data bank of 12,000 thin slices of fetal human brain tissue, Lein and his team were able to produce an immense amount of information regarding gene activity. After excising tiny bits of brain tissue, Lein used laser beams to run genetic tests on these developing portions of the brain. Lein hopes that detecting abnormal genetic expression in early development of the brain will give us insight into the genesis of psychiatric diseases, such as autism.
