Firing of on and off.
Human brains aren't digital. They're very analog.
Neuronal firing is often understood as a fundamentally binary process, because a neuron either fires an action potential or it does not. This is often referred to as the "all-or-none" principle. Once the membrane potential of a neuron reaches a certain threshold, an action potential will fire. If this threshold is not reached, it won't fire. There's no such thing as a "partial" action potential; it's a binary, all-or-none process.
Frequency Modulation: Even though an individual neuron’s action potential can be considered binary, neurons encode the intensity of the stimulation in the frequency of action potentials. A stronger stimulus causes the neuron to fire action potentials more rapidly. Again binary in nature not analog.
So what you are saying is they are discrete in time and pulse modulated. Which can encode for so much more information than how NNs work on a processor.
