Summary
Single unit recordings from the VIIIth nerve of the bullfrog (Rana catesbeiana) in response to tones reveal three populations of auditory fibers: low-frequency inhibitable fibers, mid-frequency non-inhibitable fibers and high-frequency non-inhibitable fibers. By selectively sectioning and recording from individual nerve branchlets within the inner ear, it is shown that the amphibian papilla gives rise to low and mid-frequency sensitive units and the basilar papilla gives rise to high-frequency sensitive units.
