In September 2026, the release of a complete map of an adult male fruit fly’s neural connections gave the internet a new scientific dataset to experiment with (and meme).
Within days, social media users were connecting simulations of the fly’s neural network to everything from Beat Saber and Minecraft to cryptocurrency trading and parallel parking, turning the fruit fly brain into the centerpiece of a growing series of memes and absurd experimental projects.
The trend quickly became known for viral videos showing the simulated fly brain performing increasingly unexpected tasks, such as playing video games, trading Bitcoin and driving.
So, how did a scientific breakthrough become a source of viral internet experiments? Let’s find out. Here’s what’s going on with all the “Fruit Fly Brain Simulation” memes.
Where Did ‘Fly Brain Simulations’ Come From?
The meme originated back on September 3rd, 2026, following the release of MaleCNS v1.0, a complete wiring diagram of an adult male fruit fly’s central nervous system created by HHMI Janelia’s FlyEM team, the Cambridge Connectomics Group and Google Research.
The dataset maps roughly 165,000–166,000 neurons and millions of synaptic connections, traced from electron-microscope images of a real fly.
It was released as an openly available dataset that could be downloaded and simulated, following earlier efforts such as FlyWire’s mapping of the female fruit fly brain.
Later that day, the official News from Google X / Twitter account (@NewsFromGoogle) then posted about the scientific breakthrough, informing people of the marvel of science.
Within days of the release, developers began running leaky-integrate-and-fire simulations of the connectome and connecting the fly’s sensory and motor neurons to external inputs and outputs.
On September 7th, 2026, YouTuber Ro0oney uploaded a video titled “I Put A Fly’s Conscious Brain into Minecraft,” showing how they simulated the fruit fly in the survival game Minecraft.
The video received over hundreds of thousands of views and tens of thousands of likes in just a few days, becoming one of the earliest major viral posts about the fly brain and humorous simulations using it — subsequently kicking off a slew of other jokes.
How Are The ‘Fruit Fly Brain Simulations’ Used In Memes?
As more developers, researchers and social media users experimented with the virtual fruit fly brain, the dataset quickly became a source of memes centered around putting the simulated fly into increasingly unusual situations.
Various clips shared online showed the simulated fruit fly playing games, trading cryptocurrency and controlling a vehicle, with each new experiment adding another use for the publicly available neural network.
One especially viral example shows the simulated fly brain being used to play the virtual-reality rhythm game Beat Saber.
Another viral post shows the fly brain being given $100 to trade Bitcoin, with dopamine neurons stimulated when the fly makes a profit.
Another example shows the simulated fly-brain system driving and attempting to complete the “ultimate test” of parallel parking.
The trend also includes experiments placing the simulated fly brain inside virtual environments and allowing it to explore entirely on its own.
What Are Some Related Memes?
The Fly Brain Simulations trend is part of a broader pattern in which legitimate scientific research can quickly escape its original academic context and become meme fodder online.
Once unusual or unexpected findings from a study reach social media, users can turn the research itself into the basis for jokes, screenshots and viral discussions, often focusing on the strangest details of the findings.
One example is the “Doki Doki Literature Club! Birthing Fanfiction” story, also known as the “Extreme Outlier ChatGPT User,” a viral incident that emerged in early July 2026 after researchers published a study examining how people use AI for creative writing.

The conversation around the viral “Extreme Outlier ChatGPT User” centered on an anonymous ChatGPT user identified in the paper as an “extreme outlier” who had generated thousands of fanfiction prompts about characters from Doki Doki Literature Club!, involving pregnancy, childbirth and related scenarios.
Screenshots and summaries of the findings quickly spread across social media over the summer, particularly Twitter / X, where users joked about the individual’s extraordinary dedication to the niche subject matter.
The findings came from the research paper “AI Fiction in the Wild,” published on June 24th, 2026, by researchers from the University of Washington and the University of Colorado Boulder, which analyzed more than 500,000 anonymized English-language ChatGPT conversations from the WildChat dataset.
