Brainstem auditory evoked potentials in horses and ponies.
Brainstem auditory evoked potentials (BAEPs) were recorded from 27 ponies. The peak and inter-peak (IP) latencies, V:I ratios and dispersal values were determined and the results from each category were compared with each other and with the authors' Thoroughbred BAEP data. Peak latencies were faster for ponies. The V:I ratios and dispersal values had similar characteristics in horses and ponies. In ponies there was a strong trend for IP latencies to be positively correlated with height, inter-aural distance and age. A positive relationship between I-V IP latency and inter-aural distance was confirmed in ponies as well as horses.
