Eon Systems has unveiled what could be the first complete brain emulation system controlling a body. They created a full digital model of a fruit fly brain, consisting of about 125,000 neurons and 50 million synapses, connected to a physical simulator of the fly’s body that reproduces realistic behavior.

The system completes a full perception-to-action loop: sensory signals feed into the connectome-based brain model, which then generates motor commands that move the simulated body. This breakthrough is seen as a step towards larger brain emulations, such as those of mice and eventually humans.
