n.

Abbr. EEG A graphic record of brain waves as recorded by an electroencephalograph.
electroencephalogram
(ĭ-lěk’trō-ěn-sěf’ə-lə-grām’)
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.
electroencephalogram (EEG) [(i-lek-troh-en-sef-uh- loh-gram)]

A written recording of the electrical activity of the brain. Electroencephalograms are useful in studying and detecting brain disorders.
