Last week, Google announced (via HKEPC) that it managed to fully map the brain and central nervous system of an adult male fruit fly into 3D neural shapes. As you might expect, it took approximately three seconds flat for software engineers to try and get it to play Doom.
Google reports that scientists and researchers used AI to combine millions of 2D images into the final model, and says it reconstructs over 166,000 neurons. Google says, 'This foundational map of the adult male fruit fly brain can help accelerate our understanding of the brain, and is a major milestone in neuroscience.'
By September 6 (three days later), Alex Wormuth, a software engineer at Coinbase, announced that the fly brain was being trained to play the original Doom. They say, 'Each Doom frame stimulates sensory neurons. Neural activity is mapped to game controls. Damage triggers a stimulus to two PPL101 dopamine cells as reinforcement.'
You can even watch the fruit fly play in real time via Wormuth`s website, and it not only shows the point of view in Doom, but can also show a third-person render of the fly going around Doom maps. As of the time of writing, the fly is on round 6385 and, well, it`s not very good. Sorry, fly.
But modders aren`t done here. They have also somehow managed to make the fruit fly play Beat Saber, and play it pretty well. Lyra Bubbles on X has used the brain and replays of a song in Beat Saber to teach the fruit fly where to hit and why, via Reinforcement Learning. That does mean it`s not organically reacting to the notes popping up on screen, but it is receiving input and responding to stimuli. Lyra says, 'Further training is to reduce reliance on external signals and allow it to play fully reactively with no input data.'
