FlyBrain Tic-Tac-Toe

A web page where each visitor teaches their own fly to play tic-tac-toe from no memories at all. The learning centre is all 2,597 Kenyon cells of the right mushroom body taken from the FlyWire wiring diagram, with their real input synapses, output neurons and dopamine compartments. For each candidate move the fly imagines the resulting board, a sparse set of Kenyon cells fires and recalls how good it was, and after PAM reward or PPL1 punishment dopamine the prediction error decides which synapses move. An exam of 100 games with learning switched off measures what stuck.
