The research team created a highly detailed visualization that captures every nerve connection in the brain of a fruit fly larva. This map is the most complete map ever created. It contains 3016 neurons and every connection between them: there are 548 thousand of them.
Mapping the entire brain is a complex and time-consuming task. It took over a decade to do this with a baby fruit fly. Scientists estimate that the brain of a mouse, for example, is a million times larger, meaning that the chance of mapping anything close to the human brain is unlikely in the near future.
