Evoked Potential Tests

VEP 

VEP (Visual Evoked Potential) testing checks the pathway from the eyes to the brain. The VEP test may help find the cause of certain vision problems and other conditions. Evoked potential tests measure the electrical signals carried by the nerves, quickly and safely.

​Electrodes are placed at several places on  your scalp. You are seated in front of a TV screen and asked to stare at the center. One eye is tested at a time. The stimulus is a reversing pattern checkerboard. A computer records the results as your brain responds to the stimulus. The test is pain-free and usually takes one hour. 

How do I prepare for the test?

  1. Wash your hair and skin.
  2. Do NOT use lotion or oil.
  3. Eat a normal meal.
  4. Take your normal medications.
  5. Bring your glasses or contact lenses. 
  6. Please arrive 15 minutes before your appointment time.
  7. This can be a tiring test and good results depend on your cooperation and patience during the appointment. 

SEP

SEP (Somatosensory Evoked Potential) test checks the pathway from the nerves in the limbs to the brain. The SEP test is a way to study the function of the spinal cord and nerves in the limbs. 

Electrodes are placed on your scalp, neck, shoulder and wrist for the upper body SEP, or placed on your scalp, lower back, neck, knee and ankle for the lower body SEP. The stimulus is given to the wrist or ankle. The stimulus is a mild electrical pulse which will cause a muscle twitch. A computer records the results as your brain and spinal cord respond to the stimulus. The test can take up to two hours. ​

How do I prepare for the test?

  1. Wash your hair and skin. 
  2. Do NOT use lotion or oil. 
  3. Eat a normal meal.
  4. Take your normal medications.
  5. Allow plenty of time.
  6. Please arrive 15 minutes before your appointment time.
