Electroencephalography | Definition, Procedure, Uses | Britannica In 1929 German scientist Hans Berger published the results of the first study to employ an electroencephalograph, an instrument that measures and records these brain-wave patterns The recording produced by such an instrument is called an electroencephalogram, commonly abbreviated EEG
EEG (Electroencephalogram): Uses, Procedure, Risks EEGs can help diagnose conditions like epilepsy and sleep disorders Electrodes placed on the scalp detect brain waves and send this information to a computer An electroencephalogram (EEG) test is used to check for seizures and diagnose epilepsy
What Is Electroencephalography? The EEG Test Explained It’s the primary tool doctors use to diagnose epilepsy and other seizure disorders, and it plays a key role in evaluating sleep conditions, brain inflammation, and head injuries The test is painless, noninvasive, and typically takes about 30 minutes for a routine recording
