title: Effects of stimulus frequency on adaptation in auditory-nerve fibers.
abstract: Several experimental methods of depressing the response of auditory-nerve fibers to tonal stimuli have been shown to reduce the response to signal frequencies at or near fiber CF (characteristic frequency) more than to frequencies greater or less than CF. In this study we have used a short adapting tone presented before each test-tone burst to reduce the fiber's response to the test tone. We observed the effects of changing test frequency when the adapting frequency was held constant at fiber CF. The depression in discharge rate was found to be approximately constant across test frequency.
