A 166,000-neuron fruit fly brain map was released by Google and developers immediately put it in Minecraft, taught it Beat Saber and gave it $100 to trade Bitcoin by feeding game frames into its visual neurons and turning brain activity into movements.

Oh ....why can't they just map out the human brain and open source it. God I can't wait for that 😊

the crazy part isn’t putting a fly in minecraft. it’s proving that raw neural activity can be decoded into behavior in real time. scale the decoding, and the applications get very serious

I've trained the fruit fly brain to generate misleading demos claiming to have trained the fly brain to drive cars, trade bitcoin, play beat saber and minecraft as a sociological study conducted by Harvard University. We are now complete with our study. Thank you for your time.

🚨Nobody wants to hear this but it needs to be said. > Scientists just copied a fruit fly's brain into a computer. Neuron by neuron. No training data. No machine learning. > It woke up and started walking. No one taught it to walk. No one trained it. No gradient descent. It just... knew what to do. A fruit fly brain has 140,000 neurons. A human brain is around 86,000,000,000. And we've gotten really good at scaling. Meaning with this proof, the first digital human won't be built by OpenAI. It'll be copied from someone who's already alive. Your consciousness is software. And someone just proved it can be copy-pasted. Start your day with that.

THE FLY BRAIN ESCAPED THE COMPUTER. I PUT IT INSIDE A PHYSICAL ROBOT. Scientists released a reconstructed map containing 166,700 neurons from a fruit fly. I connected it to a Strandbeest. The panel in the top-right shows the simulated brain running. Its neural activity is translated into motor commands that move the mechanical legs below. The catch: this is a computational model built from biological wiring. I engineered the interface connecting its outputs to the robot. First, the fly brain entered DOOM. Then it played Chrome Dino. Now it has a physical body. 166,700 neurons. 25 million connections. One nervous system walking through the real world.

A developer used the wiring of a fruit fly’s nervous system to play Chrome’s dinosaur game. Fly Dino, built by Mert Cobanov, uses part of a public dataset created by scientists from HHMI Janelia, Google Research, and their collaborators. The full map contains over 166,000 neurons, but Mert simulated a circuit of just 80. The game feeds information into the circuit, while a separately trained model translates its activity into actions like jumping and ducking. The bigger idea: when researchers make their work public, developers can turn scientific data into experiments anyone can try.

We gave a fruit fly $50,000 and access to the oil market. Its brain decides when to buy and sell crude. Profitable trade → dopamine. Losing streak → termination. The fly now trades commodities. Will it beat the market?

There's a fruit fly walking around right now that was never born. eon just released a video where they took a real fly's connectome — the wiring diagram of its brain — and simulated it. Dropped it into a virtual body. It started walking. Grooming. Feeding. Doing what flies do. Nobody taught it to walk. No training data, no gradient descent toward fly-like behavior. This is the opposite of how AI works. They rebuilt the mind from the inside, neuron by neuron, and behavior just... emerged. It's the first time a biological organism has been recreated not by modeling what it does, but by modeling what it is. A human brain is 6 OOM more neurons. That's a scaling problem, something we've gotten very good at solving. So what happens when we have a working copy of the human mind?

33 years of human work went into mapping a brain smaller than a poppy seed. This is all of it, every one of its 139,255 neurons. 1 female fruit fly was sliced into 7,050 layers, each thinner than a virus, then shot in 21 million photos. AI traced the cells, and humans checked every wire by hand: scientists, students and gamers clicking for fun. The final map: 139,255 neurons 54.5M synapses 8,453 cell types 150 meters of wire folded into 1 speck No one had mapped a full adult brain before, not a mouse and not a human. A fly went first. In September 2026, Janelia and Google released the male, with 166,700 neurons mapped from brain to legs through an intact neck. 2 weeks later, the internet put the fly to work: It played Doom It flew a simulated drone with zero training It landed a simulated rocket 60 times out of 80 It wrote LinkedIn posts But the map only shows where the wires go, not how strong each one is. It has no voltages and no timing, like a circuit diagram with no values on it. Nobody knows what the fly is thinking, and it posts on LinkedIn anyway. It took 33 person-years to map 1 fly, and your head holds 617,000 of them.

Fed district partisanship (and a few other vars) into the sugar and bitter taste neurons of a fruit fly. The fly predicts races by steering its body in a given direction and it manages to be 89% accurate on house races!

What makes this specific brain map such a massive leap forward? Our new connectome maps over 166,000 neurons and 125 million connections, and it extends beyond the brain to include the nerve cord, which is analogous to our spinal cord. By comparison, our 2020 hemibrain connectome project with partners, a 3D reconstruction of a portion of the female fruit fly's brain, mapped just 25,000 neurons and 20 million connections. Plus, having complete maps for both sexes is a game-changer. It finally allows researchers to pinpoint exact structural differences and study how they drive specific biological behaviors.

I made FlappyFly. I put a fly's brain into FlappyBird. It plays terribly. As a pipe approaches, LC4 neurons detect it getting closer. That input goes into the 166,700-neuron network, and when DNp01 fires, the wings beat. DNp01 is the giant fibre neuron that triggers a fly's escape when you try to swat it. I used that same escape circuit to get it past the pipes.

I GAVE A DRONE THE BRAIN OF A FRUIT FLY Not a toy network with a handful of fake neurons. The actual wiring diagram of a real fly. 166,700 neurons, 25.6 million connections, mapped one synapse at a time. I call it FlyDrones. The drone's camera becomes the fly's eyes. Motion lights up the same neurons a real fly uses to see. Spikes race through the connectome down to the neurons that drive the wings. Those spikes become throttle and yaw. The brain has zero lines of flight code, just wiring. Swing a fly swatter at it. If the giant fiber (the fly's escape neuron) fires in time, the drone dodges. Open palm, fist, rush at the camera and it reacts like a fly. Built for Tello, Crazyflie, ArduPilot/PX4 and Betaflight quads via ESP32. Code is MIT, powered by Claude. Fork it and give your drone a brain.

For the first time ever, a fruit fly brain has been trained to launch a memecoin. Not "AI inspired by a brain" — the real connectome. 165,122 neurons, 10,228,000 synaptic connections, every one traced from an actual male Drosophila by electron microscopy. Janelia FlyEM + Google Research, released CC-BY. How it works: Screenshots of the live launchpad go in through 892 retinotopic hex columns into L1 and L2 — the neurons sitting directly behind a fly's photoreceptors. All 165,122 integrate. The cursor comes back out of the descending neurons a fly actually walks with: DNa02's left-right asymmetry steers, DNa01 drives forward, DNp09 clicks. The wiring is never trained. Only synaptic gains — you don't get to invent connections the fly doesn't have. Proof its eye is doing real work: in light mode it filled 0 of 3 form fields. In dark mode, 2 of 3. Its retina is a luminance map, so invert the contrast and it goes blind. And the honest split: the fly types the description and the ticker. The rig does the name, the pair and the tax.

I uploaded a fly brain and GPT-6 Astra into a Vector robot I bought on eBay Vector was supposed to be a desk pet. Now it has a reconstructed fruit fly nervous system running inside it. MaleCNS gives it 166,700 simulated neurons and 25.6 million connections. GPT-6 Astra gives it vision. Astra sees the room through Vector's camera - furniture, walls, doors, objects on the floor - and turns the visual scene into sensory signals. The fly brain processes those signals and chooses where Vector should go next. Astra sees. The fly brain decides. Vector moves. > No joystick > No preset route > No one manually telling it to turn left or right It started roaming around my apartment, stopping in front of furniture, changing direction, and reacting to things in its path. I bought it on eBay because it looked like a cute little WALL-E. Now it has a brain, eyes, and a body. And it keeps looking at me like it knows I’m the reason it exists.

We might have just witnessed the first real mind upload. 🤯 Scientists scanned a fruit fly brain neuron by neuron, synapse by synapse, recreated it digitally, and placed it inside a simulated body. The fly walked. Groomed. Fed. No training. No prompts. No learning phase. The behavior was already in the wiring. That’s not just neuroscience anymore. That’s the first glimpse of digital minds.
