A group of scientists from Melbourne shows how brain cells living in a petri dish can play the arcade game Pong. 

Australian researchers are the first in the world to teach cultured neurons to perform a task. DishBrain, as they call their network, consists of 800,000 brain cells in a petri dish and can play the video game Pong. They found a way to interact with the cells and stimulated them to modify their activity. This creates a form of so-called synthetic biological intelligence. They published their results in Neuron.
