The all-or-none law states that a neuron either fires an action potential at full strength or it does not fire at all. Therefore, the only way for different messages to be conveyed is by changing the rate and/or pattern of action potentials. This is achieved through modulation by other neurons or through changes in the strength of synaptic connections. The size and speed of action potentials are relatively fixed and do not vary significantly under normal physiological conditions. The sodium-potassium pump activity is important for maintaining the resting potential of the neuron and restoring it after an action potential, but it does not directly influence the generation or modulation of action potentials.
