Fly-brain model reportedly makes 91 ping-pong returns in 100 seconds

A user says they trained a fly connectome model—a model of its neural wiring—to play ping-pong against itself, reporting 91 returns in 100 seconds. According to their account, each fly runs the MaleCNS graph with 166,700 neurons and 25.6 million connections. The two share trained weights but keep separate neural states. The user says viewers can watch the brains and nerve cord light up during play, with the flashes reflecting the model’s activity.
