Overview
- Researchers released the MaleCNS connectome on Sept. 3, publishing a 3D map of about 166,700 neurons and roughly 125 million synapses that covers the entire brain and ventral nerve cord.
- The map was built from millions of electron‑microscope images converted into 3D neuron shapes using machine learning and extensive human proofreading to correct automated errors.
- Within days of the public release, independent developers posted code and livestreams that run the connectome as a simulated controller for Doom, Super Mario 64, Minecraft and Beat Saber.
- Scientists and creators stress these demos use a fixed structural wiring diagram without full biophysics or self‑driven plasticity, so they do not constitute evidence of consciousness or a living fly.
- The MaleCNS extends the 2020 hemibrain work, marks the largest brain map by neuron count to date, and serves as a technical roadmap for planned connectome projects in fish and mice.
