PONG NEURONS: This is DishBrain, an in vitro system that combines human brain cells with artificial intelligence technology, which researchers at Australian biotech Cortical Labs recently trained to play the classic 1972 Atari video game Pong. Fluorescent markers show axons in green, neuron bodies in purple, dendrites in red, and all other cells in blue. Where multiple markers are present, colors are merged and typically appear as yellow or pink. Posted: October 12, 2022
