A virtual version of a fruit fly’s visual system could help scientists understand how brain networks process information. The model could also lead to more efficient AI systems.

A flexible film bristling with tiny sensors could make surgery safer for patients with a brain tumor or severe epilepsy.

Researchers have mapped the more than 500,000 connections in the intricate brain of a fruit fly larva. This map, they say, could help scientists figure out how learning changes the human brain, too.
