EEG Discs

The EEG Disc Electrodes are used mainly for EEG/ neurofeedback applications. The EEG Disc Electrodes are "snapped" into the sensor lead. Electrogel or Nuprep and Ten20 can be used for preparation. Attach the electrodes to the ears by using our earclips or use a minicab to position the electrodes.

EEG Disc Electrodes are packed per 50. The electrodes can be re-used 10-20 times. Clean the electrodes with Ivory or lukewarm water.

  • Reusable for 10-20 times
  • Packed per 50

Why it's done:

An EEG can determine changes in brain activity that might be useful in diagnosing brain disorders, especially epilepsy or another seizure disorder. An EEG might also be helpful for diagnosing or treating the following disorders:

  • Brain tumor
  • Brain damage from a head injury
  • Brain dysfunction can have a variety of causes (encephalopathy)
  • Inflammation of the brain (encephalitis)
  • Stroke
  • Sleep disorders

An EEG might also be used to confirm brain death in someone in a persistent coma. A continuous EEG is used to help find the right level of anaesthesia for someone in a medically induced coma.


  • Low blood sugar (hypoglycemia) is caused by fasting
  • Body or eye movement during the tests (but this will rarely, if ever, significantly interfere with the interpretation of the test)
  • Lights, especially bright or flashing ones
  • Certain medicines, such as sedatives
  • Drinks containing caffeine, such as coffee, cola, and tea (while these drinks can occasionally alter the EEG results, this almost never interferes significantly with the interpretation of the test)
  • Oily hair or the presence of hair spray


  • Wash your hair the night before or the day of the test, but don't use conditioners, hair creams, sprays or styling gels.
  • Hair products can make it harder for the sticky patches that hold the electrodes to adhere to your scalp.
  • If you're supposed to sleep during your EEG test, your doctor might ask you to sleep less or avoid sleep the night before your test.
