Synapse / Pong: A Dish of Neurons Meets a Moving Ball
An interactive explainer reconstructs the closed loop used in DishBrain’s Pong experiments, from electrical stimulation to neuronal response and paddle movement.
Field notes
The explainer turns the experiment into a visible feedback loop: stimulation encodes ball position, simulated spike activity selects paddle direction, and hits or misses alter the next signal. It reports a 1,024-channel electrode array, 4–40 Hz rate-coded input, and a study involving approximately 800,000 cells. A useful guardrail is built into the presentation: its 3D brain-inspired mesh is illustrative, while the cited Pong experiment used a 2D in-vitro culture.
