Beaumont performs five types of evoked potentials (EP) tests. They are BAEP, SSEP, VEP, ERG, and EOG. The test records specific sensory impulses from end organs and the body such as eyes, ears, and limbs. Thus, the EP testing evaluates conduction of sensory nerve impulses along the nerve pathway from the end organ to the brain centers.
BAEP evaluates the auditory pathway from the ear through the brainstem to the brain. A series of clicks or tones are delivered through earphones to each ear independently. The test lasts approximately one hour.

SSEP is used to evaluate the nervous system pathway(s) from nerves in the arms or legs through the spinal cord to the brain. A series of small electrical currents are applied to the skin at the extremity. The current creates a tingling and/or tapping sensation, but not pain. The patient needs to remain relaxed and comfortable during the testing. The test takes approximately 90 minutes to two hours.
VEP takes about one hour to complete. VEP is used to evaluate the visual pathways from the eye to the visual cortex of the brain. Each eye is tested separately while you sit in a chair, alert and staring at the middle of a checkerboard pattern display on a video screen.
If you cannot fully cooperate to stare at the checkerboard pattern (i.e. a baby or small child) each eye will be tested separately using bright light flashes from a strobe light or from goggles worn over the eyes.
The ERG and EOG evaluate the retina in the eye. Each test lasts approximately one hour. During the test, your eyes are stimulated with various colors of flashing and flickering lights.
