Neurophysiology Patient Information

Part of your treatment process at MNI may involve neurophysiological testing to study the bioelectrical activity of the central and peripheral nervous system as well as the electrical functioning of the brain, spinal cord, and nerves. Neurophysiology may help reveal abnormalities and assist physicians in finalizing specific diagnoses.

Patient Information about Neurophysiological Studies


More information about these studies:

  • Electroencephalogram (EEG): a test using electrodes attached to wires that allow a computer to measure and record your brain’s electrical activity.
  • Electromyography (EMG): a diagnostic procedure using electrodes to assess the health of muscles and motor neurons, the nerve cells that control muscles. Motor neurons transmit electrical signals that cause muscles to contract and an EMG translates these signals into graphs, sounds or numerical values that a specialist interprets. EMG results can diagnose nerve dysfunction, muscle dysfunction or problems with nerve-to-muscle signal transmission.
  • Evoked potential (EP): a test measuring the time it takes for nerves from different areas of the body to respond to stimulation. EP results help physicians diagnose and monitor certain conditions.
