We've uploaded a fruit fly. We took the FlyWire connectome of the fruit fly brain, applied a simple neuron model (Philip Shiu Nature 2024) and used it to control a MuJoCo physics-simulated body, closing the loop from neural activation to action. A few things I want to say about what this means and where we're going at eon. 🧵

ehm, chat... this is big they put a BCI in a rat’s brain, modeled its movements, and predicted the neural activity across behaviors with stunning accuracy, basically merging biomechanics with ai so now we could do the same with a human (Noland Arbaugh , could you help us out since you already have the neuralink?), put the modeled human in a virtual environment, load an llm, have it embodied, speed the simulation up, and get to agi.

Using monkey brain data to operate robotic arms! 🙉 Project Jenkins explores brain-computer interfaces by decoding neural activity into robotic movement and generating synthetic brain data from motion patterns. Using neural recordings from a macaque monkey named Jenkins, researchers developed models to decode brain signals into robotic arm movements and encode movement data into simulated neural activity. The project utilizes robotic arms and an interactive web console for real-time brain data generation from joystick inputs. The research paves the way for adaptive brain-computer interfaces by modeling brain activity more flexibly. Congrats to authors Dima Yanovsky, and Andrii Zahorodnii! 🦾

this is f*cking gold - I built a neural-vision prototype for humanoid robotics. With GPT Astra, my Robinhood token experiment took a very unexpected turn. CatBrain was originally meant ONLY for Robinhood tokens. Then I started experimenting beyond markets. → Cat-inspired visual processing: ON/OFF contrast channels and motion signals → A 512-unit synthetic spiking model → Neural activity decoded into left / right / hold proposals → Real fly-neuron annotations + Stonkfly source, included for future connectome experiments → Unitree H1 as the next integration target The visual design draws on mechanisms studied in the feline visual system. Code, data and research plan on GitHub in reply.

I can't f*ckin believe it - I BUILT a cat-inspired visual system for a ROBOT DOG A camera feeds visual data into a simulated feline neural system - and its activity controls where the robot moves. → 20,480 simulated neurons processing vision → 8 orientation channels detecting edges → Camera → NEURAL ACTIVITY → target → movement → Turns toward moving targets in REAL TIME → Runs completely OFFLINE → Connected to a Unitree Go2 through its SDK Movement appears right - it turns right. Left - it turns left. Centered - it locks on. The robot’s controller handles balance and legs. CATBRAIN handles where it looks and follows. The project is still IN DEVELOPMENT - you can follow every step on GitHub. I attached the link in the replies.

For the first time in history, GPT-6 Astra created a fly that is simply a fly. Not a chatbot pretending to be a fly. Not a simplified animation. A digital fly running its own connectome brain, perceiving a real room through its own senses and interacting with the environment using the power of AR. The entire loop is surprisingly wild: Spectacles capture the retina, light rays, hands, and the surrounding room → the room is converted into an inventory → sensory information is fed into the fly’s neural system → the MaleCNS connectome processes it → descending neurons and motor pools generate actions → the commands return to the Spectacles → wings, legs, and head respond. In other words, the fly sees through its own eyes, processes the world through its own simulated brain, and acts through its own virtual body. We are moving from AI that generates outputs to AI that actually has a body, senses, a brain, and a closed perception-action loop. The 🪰 is no longer just simulated. It is experiencing a world The developer Pavlo Tkachenko is pinned below in the post

Giving Microduck object-tracking vision capabilities! 🦆👀🤖 It can now play fetch and doesn't get confused by other objects. Using Roboflow Trackers library I made Microduck keep track of the different objects in its sight and has a control policy for reaching the ball it tracks. Open-Source code below 👇

I made a fictional, Hinge-like dating app for the fly. Profile pixels feed the neural model. Measured dopamine-neuron activity drives a like/pass/rose rule. You can watch every decision, inspect the evidence, and replay exactly what our boi Francis sees. Built it on top of by Fly / Wirehead by Matty Hempstead, but replaced the scrolling feed with a fictional dating world. Repo is in the reply.

I uploaded both a male and female fruit fly's real brains into Minecraft, and got them to actually flirt. The male's courtship song (produced by his wings) , the real signal fruit flies use to attract a mate, is playing live through Minecraft note blocks, a direct translation of real neuron activity, not a sound effect. And the female is genuinely responding, standing closer, driven by her own real neural circuit. Two real animals from inside minecraft! #fly001

166,700 fruit fly neurons are walking a robot cat across a desk right now. In September 2026, Google Research and HHMI Janelia mapped every neuron and every connection in an adult male fruit fly's full nervous system, brain, optic lobes, and ventral nerve cord together, and published it in Cell. The number is staggering on its own: 166,700 neurons, roughly 125 million synapses, the most complete nervous system map of any animal ever built. Now that exact wiring is running live, simulated neuron for neuron, inside a small robotic quadruped equipped with a camera and motion sensors. Movement comes in through the sensors, the biological circuitry fires the way it always did, and the output drives the robot's legs directly. No one wrote the balance logic. No one coded the gait. The insect's own nervous system does that job, just on legs it never had. To be clear about what this is and isn't: nothing biological is alive in this loop. It's a full computational reconstruction of real neural wiring, controlling hardware instead of an insect body. The brain is real. The body is borrowed. Remarkable proof that a mapped nervous system can drive any body you give it, or a preview of something people aren't ready to think through yet?

I did these movements for 30 on 30 off for 5 sets with 60 seconds between sets. These patterns build the stuff adults forget about and kids desperately need coordination, rhythm, stability, mobility, body control, & athleticism. Give the circuit a try. Until next time, doggies.

A former participant in a secret US legacy program reveals how gifted children were trained to pilot UAPs using pure consciousness. JOZAK: “They called it the Prometheus system.” “They’re not flown with joysticks. They’re flown through the mind.” “You take your consciousness outside of your body and you become that object. I would lay in a deep meditation… shift my consciousness into the vehicle and become it… pilot it up and down, move it left and right.” “I would shift my consciousness into it… like a split-screen video game. Third-person view on one side, first-person on the other. By flip-flopping the two, I would make it move.” “They monitored my brain waves and built a neural interface… so an Air Force guy with a controller could push up and the craft would move using my brain signals.”
