For decades, the only complete wiring diagrams of a nervous system, connectomies, were for tiny creatures like the 302-neuron sea of elegans worm.
That changed in October 2024, when Flywire mapped an entire adult fruit fly brain.
About 140,000 neurons and 50 million connections.
In the same issue of nature, researchers showed the map could be brought to life as a simulated brain that predicted some real fly behavior.
A month later, EPFL released FlyGym, a free, physics-simulated fruit fly body you could drive with code.
By early 2026 the pieces were starting to connect.
The startup Eon Systems wired a connectome brain into a virtual fly body and got it walking and grooming.
But it was the release of MailCNS version 1.0 in September 2026, combined with AI coding assistance, that put this within anyone's reach.
