Abstract

Short-latency veslibular-evoked potentials to pulsed linear acceleration were characterized in the quail. Responses occurred within 8 ms following the onset of stimuli and were composed of a series of positive and negative peaks. The latencies and amplitudes of the first four peaks were quantitatively characterized. Mean latencies at 1.0 g ms-1 ranged from 1265 ± 208 μs (P1, N = 18) to 4802 ± 441 μs (N4, N - 3). Amplitudes ranged from 3.72 ± 1.51 μV (P1/N1, N = 18) to 1.49 ± 0.77 μV (P3/N3. N = 16). Latency-intensity (LI) slopes ranged from -38.7 ± 7.3 μs dB-1 (P1, N = 18) to -71.6 ± 21.9 μs dB-1 (N3, N = 15) and amplitude-intensity (AI) slopes ranged from 0.20 ± 0.08 μV dB-1 (P1/N1, N = 18) to 0.07 ± 0.04 μV dB-1 (P3/N3, N = 11). The mean response threshold across till animals was -21.83 ± 3.34 dB re: 1.0 g ms-1 (N = 18). Responses remained after cochlear extirpation showing that they could not depend critically on cochlear activity. Responses were eliminated by destruction of the vestibular end organs, thus showing that responses depended critically and specifically on the vestibular system. The results demonstrate that the responses are vestibular and the findings provide a scientific basis for using vestibular responses to evaluate vestibular function through ontogeny and senescence in the quail.
