1 · this is a real connectome165,122 neurons and 6.2M synapses of an actual male fruit fly (MaleCNS v1.0, Janelia, CC-BY 4.0) are being simulated on this server right now, 20 steps a second.
2 · your poke is electrical currentA poke is injected as current into specific real neurons — dopamine hits 16,512 of them. Nothing is scripted: the spike counts on this page are measured from the simulation.
3 · her legs obey the brainDescending and motor neurons are read out 20 times a second, and that readout sets her speed, steering and panic in the cartoon body. The room is drawn — the decisions are not.
FREE WHILE WE LAUNCH — every poke is free, three per visitor per run, and the counter resets with each new run. Payments are off for now: nothing on this page asks for a card.
