Auditory Brainstem Response

Evaluates hearing function, by measuring the natural electricity given off by the brain. This test is like a hearing test and looks mainly at the auditory nerve. During this test the patient does not have to do anything but relax. This is the same test that is used for the newborn hearing screenings. To obtain results small sticker electrodes are placed behind each ear and on the forehead. The electrodes do not administer any shocks; they simply pick up the natural electricity given off by the brain as the signal travels through the auditory system.
