Micromechanics of the reptilian ear

This paper reviews selected physiology and anatomy of the lizard peripheral auditory system and presents the implications of these data for understanding cochlear micromechanics. The reasons for studying the micromechanics of the lizard ear are presented along with the difficulties in conducting such studies in the mammal. Data from the Anguid and Iguanid families of lizards demonstrate the influence of the hair cell system on neural tuning. In addition, evidence from the Iguanid suggests that cilium length may help determine neural tonotopic organization. In general, the reptilian research presented shows the importance of the hair cell system for determining the tuning of associated nerve fibers and in understanding the transduction process in general.
