How Computationally Complex Is a Single Neuron?

Scientists taught an artificial neural network to imitate a biological neuron. The result offers a new way to think about the complexity of brain cells.

Our mushy brains seem a far cry from the solid silicon chips in computer processors, but scientists have a long history of comparing the two. As Alan Turing put it in 1952: “We are not interested in the fact that the brain has the consistency of cold porridge.” In other words, the medium doesn’t matter, only the computational ability.
