Abstract
The peripheral auditory system of the alligator lizard (Gerrhonotus multicarinatus) has been studied extensively; however, limited data are available for the whole‐nerve (AP) response. Could the AP serve as a convenient monitor of the condition of the ear during experimentation? AP responses to tone burst acoustic stimuli of various frequencies were recorded from the alligator lizard and three measures using the AP response were obtained. (1) Averaged suprathreshold AP responses were related to primary auditory nerve fiber activity. (2) AP thresholds were compared to single‐unit thresholds. (3) AP excitatory tuning curves were compared to single‐unit tuning curves. The good agreement between AP responses and single‐unit data indicate that the AP is a useful tool for measuring the physiology of the peripheral auditory system in the alligator lizard.
