The brainstem auditory evoked response test is performed to assess auditory nerve and auditory brain stem function.
You will lie on a reclining chair or bed and remain still. Electrodes will be placed on your forehead and on each earlobe, or behind your ears. You hear clicking noises or tones through earphones and the electrodes pick up the brain's response and record it on a graph.
This test does not hurt. The test takes at least 1 hour and you should feel no aftereffects.
