The EEG (electroencephalogram) uses highly conductive silver electrodes coated with silver-chloride and gold cup electrodes to obtain accurate measures of effectiveness, resistance caused by dura mater, cerebrospinal fluid, and skull bone.
Monopolar Technique : the use of one active recording electrode placed on area of interest, a reference electrode in an inactive area.
Bipolar Technique : the use of two active electrodes on areas of interest.
Measures brain waves (graphs voltage over time) through electrodes by using the summation of many action potentials sent by neurons in brain.
An EEG can determine changes in brain activity that may be useful in diagnosing brain disorders, especially epilepsy. An EEG may be helpful to confirm, rule out or provide information that helps with management of the following disorders:
Epilepsy or other seizure disorder
Brain dysfunction that may have a variety of causes (encephalopathy)
The EEG has become a widely used and successful research tool
It is a practical candidate that offers valid measurement
It contributes objective information that can be easily viewed and measured
It is a versatile system that allows for a diverse application of the information it provides:
From therapeutic endeavors, and enhancing educational efforts, to offering information and insight that has helped to improve pilots’, conductors’, and drivers’ vigilance performance, as well as strengthening the base of general knowledge in a way that has helped to improve our everyday lives.
