1. A graphic record of brain waves representing electrical activity in the brain, used especially in the diagnosis of seizures and other neurological disorders.
2. ◆ 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

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

From Science Daily

Then came the neonatal intensive care unit, the application of a web of electrodes to the scalp, the first seizure caught on electroencephalogram, a massive dose of phenobarbital, consent for a “whole genome sequencing”—just one of many tests, no more portentous than the last—a brief return home, more seizures, and another hospital stay.

From Slate

In the letter, Dr. Brian P. Monahan, the Navy rear admiral who serves as the on-site doctor in the Capitol for members of Congress and the Supreme Court, said his examination of Mr. McConnell, Republican of Kentucky — along with a brain M.R.I., an electroencephalogram study and a neurological consultation — had found no sign of a seizure disorder or stroke.

From New York Times
