Mapping the human brain in detail could help to unlock some of its mysteries, but our own brains are such amazingly intricate organs that we’re going to be waiting a while for that to happen. Still, scientists just took an important step towards that goal.
A team has just created a high-definition, 3D picture of something a little smaller – the brain of a fruit fly. Showing every single one of the brain’s 100,000 neurons, it’s the most complete brain map ever created.
