Groups of nerves firing in staggered cycles code frequencies above 300 Hz

Evidence

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 M. Howard, Jamie Angus, Acoustics and Psychoacoustics, 900
