electroencephalogram   (ĭ-lěk'trō-ěn-sěf'ə-lə-grām')  Pronunciation Key 
A graphic record of brain waves representing electrical activity in the brain, used especially in the diagnosis of seizures and other neurological disorders. ◇ The instrument used to record an electroencephalogram is called an electroencephalograph.It generates a record of the electrical activity of the brain by measuring electric signals using a set of electrodes attached to the scalp that act as transducers. Differences of electric potential between different parts of the brain are measured by a portable set of galvanometers and printed as a wide paper strip with multiple simultaneous waveform tracings that have standard configurations in the normal brain.
