WebIn the auditory system, it is a measure of frequency selectivity. For example, in recordings from an auditory nerve fiber, the threshold is usually defined as a fixed increase in firing rate in response to a pure tone. Typically, tuning curves are V-shaped with a characteristic frequency (CF) or best frequency ...
