SummarySeveral parameters of the peripheral auditory physiology of the bobtail lizard have been examined with respect to the time of the year. These include gross-potential and neural thresholds across the entire hearing range as well as a standard measure of gross-potential size and an estimate of the success in recording primary auditory afferents.1.The results do not indicate any pronounced changes in hearing ability across the year. This contrasts with earlier reports by Johnstone and… 
Peripheral auditory processing in the bobtail lizard Tiliqua rugosa
TLDR
Fibres of low characteristic frequency show a characteristic change in their response pattern with stimulation frequency; it is suggested that primary suppression plays an important role in shaping the very phasic response to tones at the fibres' upper frequency range.
Peripheral auditory processing in the bobtail lizard Tiliqua rugosa
Summary1.Primary auditory fibres in the bobtail lizard phase-lock up to a maximal frequency of 1.0 to 1.3 kHz at 30 °C body temperature.2.Phase histograms frequently have two peaks, 180° apart. The
Peripheral auditory processing in the bobtail lizard Tiliqua rugosa
TLDR
Primary auditory-nerve fibres of the bobtail lizard have asymmetrical, V-shaped frequency-threshold tuning curves, which permit a separation into the same low-CF and high-CF groups.
Lizard auditory papillae: An evolutionary kaleidoscope
Binaural processing by the gecko auditory periphery.
TLDR
The neural response accurately reflects tympanic directionality, and most neurons in the auditory pathway should be directional, as well as best ITD and click delays match interaural transmission delays.
A comparison of auditory brainstem responses across diving bird species
TLDR
Vocalization parameters were measured for each species, and showed that with the exception of the common eider, the peak frequency of all species’ vocalizations measured here fell between 1000 and 3000 Hz, matching the bandwidth of the most sensitive hearing range.
Otoacoustic Emissions in Amphibians, Lepidosaurs, and Archosaurs
TLDR
This chapter will provide an outline of this work and recommend that all the information discussed in this chapter needs to be understood in the light of the source of the energy that manifests itself in OAEs in nonmammals.
Evolution of structure and function of the hearing organ of lizards.
TLDR
This review considers the possible influence of various morphologic features on function, and correlates these features with physiologic response parameters.

Gross potentials recorded from the cochlea of the skinkTiliqua rugosa
TLDR
The summating potential recorded from the scala tympani increased eight to ten-fold during spring, and there was an oblique shift in the intensity curves of all gross response components to the poorer responses at other times of the year.
Seasonality of Two Midbrain Auditory Responses in the Treefrog, Hyla chrysoscelis
Multi-unit responses and averaged evoked potentials (AEPs) were recorded over 14 months from the torus semicircularis, a midbrain auditory nucleus, in Hyla chrysoscelis. Audiograms collected during
Nonlinear Properties of the Peripheral Auditory System of Anurans
TLDR
A series of electrophysiological experiments were conducted in order to determine the nonlinear behavior of the anuran’s peripheral auditory system, and the results have interesting implications regarding the origin of nonlinearities, as well as the mechanical basis for frequency analysis, in the vertebrate inner ear in general.

Spontaneous and driven responses of semicircular canal primary afferents in the unanesthetized pigeon.
TLDR
The relation between the spontaneous mean ISI and its standard deviation (SD) for SC primary afferents in the unanesthetized pigeon is best described by a power function model, which provides a significantly better fit than does a linear model.
