An auditory nerve codes for frequency of a stimulus by firing an action potential for only a particular cycle of a stimulus which is called . Any single auditory neuron is not capable of following the stimulus on a cycle-by-cycle basis, because they cannot fire beyond a certain rate (500-600 Hz in humans) effectively. However, a group of neurons can fire for different cycles of a stimulus, which is explained by the theory/principle.
