Open simulation reconstructs a fruit fly’s neural system for behavioral experiments

Google mapped the neurons of a fruit fly, and researchers have recreated that structure in software. The simulation’s code is publicly available, allowing users to run their own experiments with the virtual insect, including placing it in a Rabbit R1 and observing activation of its escape circuit when the device is shaken.

The simulated fly has also been used for tasks including playing Doom and parallel parking. In theory, the model could reproduce the fly’s decisions and movements, but it remains unclear how accurately it captures the behavior or internal states of a living organism.
