Somebody mapped a fruit fly's brain down to the last wire β 138,639 neurons, 15,091,983 synapses β and published it for free. We did not ask what it was for. We asked what it could be conditioned to do.
QUESTION
EVERYTHING.
IS REAL.
TO THE BAD GUYS.
ROBINHOOD
βRESPONSE STRENGTH (peak MBON z-score)
RABBIT HOLES
Targets ranked by how hard SUBJECT 7 reacted. A strong reaction means interesting, never true.

BRIEF THE ASSET
Hand SUBJECT 7 a new target. It becomes an odour, and the implanted connectome answers it.
These are real Drosophila olfactory receptor channels. The same topic always produces the same smell β the encoder is SHA-256, nothing random.

BOUNTIES
Things the cat wants brought in. Bring one and get paid in $THC. Entering is free β you are answering a request, not buying a run.
CASE FILES
Debriefs. Target, odour, and how the asset answered. Status describes the response, never the claim. Every case re-runs from its seed.
Nothing matches that. The cat has no opinion it hasn't already filed.
ASSET CAM
Real connectome. Real simulation. The smell is our invention.
The measured circuit. Every number on this page is computed here.
β
Wiring and spiking are real: 138,639 neurons, 15,091,983 synapses, leaky integrate-and-fire. The mapping from a topic to a smell is invented and deterministic β a fly has no concept of a conspiracy. The response is real; the label is ours.

Two runs, and only one of them counts. Everything measured β the tingle, Kenyon sparsity, the learning curve, teachability β is computed on the olfactory learning circuit: ORN β antennal lobe projection neurons β Kenyon cells β MBONs, with dopaminergic and APL neurons. 8,572 neurons, 606,719 synapses.
Brain Cam can also show a second run over the whole connectome (138,639 neurons, 15,091,983 synapses, LIF with a 1.8 ms synaptic delay and a 5 ms alpha synapse). That one is for looking at, not for measuring. The full network cannot hold biologically sparse Kenyon coding and a clean mushroom-body readout at the same time β pushing sparsity down with APL inhibition drags the readout down with it, and the best whole-brain setting found was still about six times too dense. The circuit does both at once, so the circuit stays the instrument.
