Auditory evoked potentials

Over a headphone, patients hear several sounds rapidly following each other, generating electric potentials within the acoustic nerve. Electrodes on the surface of the head help measure the electrical potentials, which makes the examination of the acoustic nerve and communicating brain areas of the lower and middle brainstem possible. AEP are regularly measured in case of a suspicion of tumors of the acoustic nerve (e.g., acoustic neuroma), multiple sclerosis or other diseases.
