脑干听觉诱发电位 (BAER) 测试结果，异常，犬

Waveforms representing central auditory processing in a dog with abnormal hearing. In a dog with normal hearing, within 12 milliseconds the two waveforms would be in phase, with peaks and troughs occurring at the same times; however, in this deaf dog, the waveforms are never in phase, indicating dysfunctional central auditory processing.
