Synchronized responses of primary auditory fibre-populations in Caiman crocodilus (L.) to single tones and clicks

Abstract

Measurements of the responses to tones and clicks were made from single primary auditory fibres of the caiman. The distribution of the amplitude and phase of the fundamental component of the response rate modulation over the best frequencies of the fibres is comparable to that reported in the cat, despite the fact that the basilar membrane in caiman is only 4.5 mm long. However, much higher intensities are needed in the caiman (75-85 dB SPL) than reported in the cat (20 dB SPL) to obtain systematic distributions of the phase of the responses, probably due to the larger scatter of the phase responses in the caiman. The slopes of the phase distributions are very similar to those in cat. Single unit phase responses as a function of stimulus frequency at 85 dB SPL can be approximated by one, or in fibres with low best frequency, two straight lines. At lower intensities the deviation of the phase-frequency responses from a straight line increases as the group delay at the best frequency becomes larger. The shortest latencies of click responses are obtained with rarefaction clicks. Group delay estimates obtained from the responses to clicks and from the straight line approximations of the phase-frequency responses are related in a wa...Continue Reading
