"Brains, Machines, and Mathematics" by Michael A. Arbib shows that any
digital computer is equivalent to the simplest of neurons, the
McCulloch-Pitts neuron because
1) A digital computer can be created using of AND, OR, and NOT gates
2) the above three gates can be simulated by giving McCulloch-Pitts
neurons varying integration characteristics.
