Somatosensory Evoked Potential Test (SEP or SSEP)
SSEPs are used to test the function of the specific sensory systems and their brain connections. SSEPs involve EEG recording along with different types of stimulation.
An SSEP test studies the relay of body sensations to your brain and how the brain receives those sensations. A stimulating electrode is placed on your arm or leg, and it generates an electrical signal. Recording electrodes are placed on your head and/or spine.

How to prepare for an SSEP:
- Please wash and dry hair thoroughly. Do not use hair products of any kind.
- Please wash and dry skin thoroughly. Do not use any oils or lotions of any kind, including cosmetics.
- Take all medications as normal. Bring medication list to test.
- Eat a regular meal prior to the test.
- Wear loose fitting top and bottom. The technologists will need access to:
- Lower back
- Hip bone area
- Back of the neck
- Lower part of the arm, near the wrist
- Both feet
Visual Evoked Potential Testing (VER)
The VER is used to test the function of the specific sensory systems and their brain connections. VER testing involves EEG recording along with different types of stimulation. A VER test assesses the visual systems. You will look at the checkerboard patterns on a TV screen during recording brainwaves.

How to prepare for a VER:
- Please wash and dry hair thoroughly. Do not use hair products of any kind.
- Take all medications as normal. Bring medication list to test.
- Eat a regular meal prior to the test.
- If you wear glasses or contacts, please bring them with you to the test.
- Please arrive on time.
Brainstem Auditory Evoked Response Test (BAER)
What is a BAER?
A BAER is a medical test that evaluates the integrity of your nerve pathway from the ear to the brain. This test may help uncover the cause of a hearing or balance problem, along with other symptoms.
What is the procedure for a BAER?
You will lie on an exam table in a comfortable position. The more relaxed you are, the more successful the test (you may even sleep) will be. Several surface electrodes are attached to your scalp and ears. They are attached with an adhesive paste that washes off easily. Earphones are placed over your ears to deliver the stimulus (clicks or tones). The stimulus is usually given to one ear at a time. A computer records the results as your brain responds to the stimulus.

How to prepare for a BAER:
- Wash and dry hair and skin thoroughly on the day of your BAER. Please do not use any oils or lotion of any kind, including cosmetics.
- Eat a normal meal.
- Take medications as usual and remember to inform us of all you medications.
- Arrive on time for you test to fill out any necessary forms and answer any questions.
