Scientists have mapped the neurons responsible for every behavior executed by fruit fly larvae, the first small step toward creating a map of neurons in the human brain. Researchers broke down the few behaviors fruit fly larvae are capable of and associated them with the 10,000 neurons in their brains and nerve cords. "It's a proof of principle. It's possible to classify neurons in terms of what decisions and actions they cause," said study leader Marta Zlatic, a biologist at the Howard Hughes Medical Institute's Janelia Farm research center.
