Application and use of prime electrodes and eye leads.
Often the standard International 10-20 System of electrode placement doesn't provide enough information regarding abnormal EEG activity. The application and use of prime electrodes can help to localize abnormal activity and also establish polarity of activity past the end of the chain of a bipolar montage. The proper application and use of eye leads can help to determine if EEG activity is abnormal or a non-cephalic artifact. This article will outline application and use of prime electrodes and eye leads.
