Brainstem Auditory Evoked Response
The Brainstem Auditory Evoked Response (BAER) test, also known as auditory brainstem evoked response, detects abnormalities within the ear or brain by measuring brainstem responses to clicks or tones in the ear. This procedure is effective in diagnosing nervous system abnormalities and hearing loss.
During this test, electrodes are placed on the scalp and subtle noises are delivered to one ear. The brain’s responses to these noises are recorded by the electrodes and analyzed to evaluate neurological function and diagnose hearing, balance or brain abnormalities.
