Surface-recorded auditory brainstem responses in the dog

Surface-recorded auditory brainstem responses were obtained from 8 dogs. Trains of clicks were presented by earphone at a level approximately 80 db re human threshold. In one dog an undetected otitis media was signalled by wave-form latency delay. Jewett Waves I-V were found with order and spacing much as with human Ss, but the early waves were more prominent. It was concluded that electric response audiometry may have a bright future in electrophysiological, veterinary, and pharmacological research on audition in animals.
