Visual Evoked Potential (VEP)

This safe and painless test evaluates the visual (sight) nervous system. You will relax in a reclining chair, and a few electrodes will be applied to your head. You will then be asked to watch a flashing checkerboard pattern on a TV screen. Tiny electrical signals from your brain will be picked up by the electrodes and sent to a computer that will record and print out results. These results will be interpreted by a neurologist.

Time:                                                                                                                             Approximately 60 minutes
