In biology individual cells are self organising and do not only what is best for them but also the whole. Their behaviour is good for the organ, and the organ works alongside the other organs. It also occurs in a fractal manner with cells working with the organ and vice verse to make for a healthy body. This is horizontal and vertical cooperation.
Error correcting processing in the brain allows for certain inputs and neutrons to be wrong but for the output to be “correct” due to sense-making. This is a mutual symbiotic relationship rather than a game theoretical one.
