Nerve firing intervals are integer multiples of the stimulus period

Evidence

However, due to phase locking, the time between firings for any particu­ lar nerve will always be an integer (1, 2, 3, 4, …) multiple of periods of the stimulating waveform and there are a number of nerves involved at each place. A “volley firing” principle has also been suggested by Wever (1949) in which groups of nerves work together, each firing in different cycles to enable frequencies higher than 300 Hz to be coded. — David Howard, Jamie Angus, coustics and Psychoacoustics, 917
