Brainstem Auditory Evoked Response (BAER)

This safe and painless test auditory (hearing) nerve and brain connections. You will relax in a reclined position as a few electrodes are applied to your head. You will then be fitted with earphones through which you will hear a clicking noise. As the noise travels through the various pathways to the brain, tiny electrical signals from the brain will be picked up by the electrodes and sent to a computer that will record and print out the results. These results will be interpreted by a neurologist.
