What is it?

It is a test that examines whether signals are conducted normally over the nerve pathways.

  • A BERA (Brainstem Evoked Repose Audiometry) tests the pathways for hearing, which are closely related to the pathways responsible for balance.
  • An MEP (Motor Evoked Potential) tests the motor pathways.
  • An SSEP (Somato Sensory Evoked Potential) tests the sensory pathways.
  • A VEP (Visual Evoked Potential) tests the visual pathways.

What is the process?

A staff member of the Neurology Department will place electrodes on your head, arm and/or leg. To do this, a type of gel and some tape will be used.

Then various stimuli will be given.

  • BERA: sounds via headphones or earphones
  • MEP: a special coil will be placed about your head and will emit a magnetic pulse
  • SSEP: electrical shocks on the pulse or ankle
  • VEP: looking at a checkerboard pattern on a screen
  • BERA: tell staff if you wear a hearing aid.
  • VEP: if you have glasses or contact lenses, do not remove them. You must be able to follow the stimulus on the screen.
