Scientific definitions for electroencephalogram
[ ĭ-lĕk′trō-ĕn-sĕf′ə-lə-grăm′ ]
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.
