Evoked potentials

 

Evoked potential tests assess the nerve pathway from sensory inputs to the brain. During all tests, a small number of electrodes will be applied to your scalp. Different stimuli are then given, depending on which pathway is being assessed:

  • For a visual evoked potential (VEP), a checkerboard or flashing light will be shown
  • For a brain stem auditory evoked potential (BAEP), clicking noises will be presented through a set of headphones
  • For a samatosensory evoked potential (SEP), nerves in the hands and/or feet will be stimulated using small electrical impulses
     

Prior to all evoked potential tests, please ensure your hair is clean and do not use any hair products e.g., gel, hairspray. Continue to take your usual medication, and please bring a list of current medication.

Please bring any glasses or contact lenses you may wear to a VEP.

Do not listen to excessive noise for at least 24 hours prior to a BAEP.

Wear comfortable, loose-fitting clothing to an SEP.
