The routine EEG is the most common test for epilepsy. The Archer Medical EEG Technologist first measures the patient’s head so that the electrodes, which are small, metal, cup-shaped disks attached to wires, can be placed in the correct position. A wax crayon, which can be easily washed off later, is used to mark the points on the scalp. Next, the Archer Medical EEG Technologist applies the electrodes, usually using a paste that holds them in place for up to several hours.
