HERBRAIN
Illustration of a female fruit fly in a glass box

Every trade
activates a neuron.

Her brain is simulated from 139,248 mapped neurons. Trading fees feed her and help her break out of a glass box. When trading stops, her energy runs out.

One fly.
Three fee streams.

HERBRAIN uses a published map of a female fruit fly's brain, with 139,248 neurons and their connections traced using an electron microscope. We use that map to simulate her brain.

Fees from token buys and sells become inputs to specific groups of neurons. While she is in the box, one share feeds her and the rest helps her escape. Once she is free, the escape share switches to courtship.

Food keeps her alive.

30%

30% of fees goes to food. These inputs stimulate her 129 sugar receptor neurons and restore her energy. A full energy reserve lasts 48 hours without food. If it reaches zero, her simulated life ends.

Food allocationNo data

Help her get out.

70%

The other 70% goes toward opening her box. It stimulates 454 neurons that detect approaching objects and connect to the Giant Fibre escape pathway. The planned release target is $5,000 in box fees. Test runs use the target shown in the Box details.

Box allocationNo data

Then find a mate.

After release

Once she is free, the 70% shifts to the mate stream. It stimulates 126 ORN_DA1 neurons that detect the male scent cVA. We read the response in pC1, a group of cells involved in courtship.

Food inputs did not activate IPC in the original model, so we use DH44 to read the food response and still show IPC here. These values describe groups of neurons. Dots in the brain map show cell positions, not live firing.

Each fly
has a name.

Each fly starts with enough energy for 48 hours. Food fees top it up. If her energy reaches zero, her life ends and becomes part of this history. A new fly starts with a new name, the same token, and the same rules. Her progress resets, including the box total.

A mapped brain.
A simulation we built.

The brain map comes from the FlyWire female connectome, a dataset of neurons and their connections. The viewer shows 17,000 sampled cells from the model's 139,248 neurons, including all available cells in the circuit groups shown above.

We use measured cell body positions where available. Other cells use reference positions from the annotations. Coordinates are scaled for display. The map shows where cells are, without drawing every connection between them.

The fly, her movements, and the view inside the circle are illustrations. They do not show a real fly's behavior or measured internal anatomy. The brain map you can explore uses measured cell positions.

We chose the rules that turn fees into neural inputs, food energy, and progress toward escape. These are parts of the simulation. They do not show that the fly has feelings, intentions, language, or consciousness.
