What is an "Electroencephalography" or "EEG"?

Charles Ribak, Ph.D. (Professor of Anatomy and Neurobiology, UC Irvine School of Medicine) gives expert video advice on: If I have one seizure, will I definitely have another?; Is there a cure for epilepsy?; What are the surgical treatments for epilepsy? and more...

With regards to the diagnosis and treatment of epilepsy, Electroencephalography or EEG involves connecting the head to various electrodes to a machine that would monitor activity between different points on the surface of the brain. This monitoring could be for an hour, it could be for 24 hours. There are now techniques where we can use telemetry for sending the information back. In other words, there's a helmet that has all the electrodes, and the information gets stored, and it can be reviewed over a 24 hour period. Electroencephalography or EEG is used by neurologists to diagnose whether the seizure is part of an overlying disease known as epilepsy.
