Electroneurophysiology Technologists

To have a better understanding of ENPs, we reached out to our partners in the Canadian Association of Electroneurophysiology Technologists (CAET) and the Canadian Board of Registration of Electroencephalograph Technologists (CBRET) for an overview.

Electroneurophysiology Technologists (ENP) perform electroencephalograms (EEG) and/or evoked potential examinations. During an EEG, the electrical activity of the brain is recorded by placing electrodes on the patient’s head. EEGs may be ordered to help diagnose various problems with the brain, such as:

  • seizures and epilepsy
  • strokes and bleeding in the brain
  • degenerative brain disease
  • brain infections

Evoked potential (EP) testing records electrical activity of the brain and spinal cord after a deliberate external stimulation. The visual (eyes), auditory (ears), motor (muscle) and sensory nerves can all be tested for such things as:

  • spinal cord injuries
  • tumours on the nerves
  • inflammation of the nerves

Because EPs can look at a variety of neurological pathways, they are sometimes in the operating room to provide information to surgeons as they operate (allowing the surgeon to make decisions based on the monitoring results).
