Google and collaborators mapped a fruit fly's brain containing 11,700 neuron types and 166,000 neurons total. Developers then used this map to create simulated fly brains that learned to play Doom and other games like Super Mario 64 and Beat Saber, with the simulated neural networks processing game inputs and controlling gameplay in real time.
Google Research and HHMI Janelia have completed a connectome map of the male fruit fly brain, containing 166,000 neurons and 125 million synaptic connections. This largest-to-date brain map, achieved through AI and human verification, will help scientists understand how brains work across species and potentially repair neural damage.
