The brain’s all-or-nothing neuron firing resembles binary logic

Evidence

When the impulses coming into a neuron exceed a certain threshold, then that neuron, in turn, emits a pulse. Immediately this begins to feel, to McCulloch and Pitts, like logic: the pulse or its absence signifying on or off, yes or no, true or false. — Brian Christian, The Alignment Problem, 12
