electroencephalogram  (-lktr-n-sf-l-grm)
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.
