Brainstem Auditory Evoked Potential (BAEP or BAER for brainstem auditory evoked response)

This test evaluates the auditory portion of the nervous system from the ears through the brainstem and the auditory portion of the brain. Electrodes are pasted to the scalp, and the patient wears headphones which deliver a series of clicks and tones to each ear separately. This is NOT the same as a hearing test (or audiogram), and it provides different information.
