What is EEG?

EG is an abbreviation for electroencephalography. This term was introduced in 1929 by German psychiatrist Hans Berger.
Generally, EEG is a bioelectric brain activity test. Brain cells communicate with each other through electrical pulses. EEG is helpful in detecting potential disorders associated with this activity.
The test records the course of the brain waves. Small electrodes are placed on the skin surface of the skull. Electrodes record changes in electrical potential on the surface of the skin from neuronal cortical activity and send signals to the computer that records them.
Electric pulses in the EEG record look like wavy lines with mountains and valleys - it's an electroencephalogram.
Electroencephalogram is are evaluated by the qualified physicians. Any abnormality may be a symptom of epilepsy or other brain disease.
