Neural Coding and Auditory Perception
... When FT was equal to the CF, AN fibers with low CF (<2 kHz) tended to fire at 1/CF intervals. In comparison, responses of CN units had fewer peaks and were shorter in duration. In particular, primary-like-with-notch and onset responders typically showed one peak for broad phase transition stimuli an ...
