Try to relax and remain still. Avoid talking during the test. You will sit in a reclining chair or lie down on an exam table in a softly lighted room. The technologist will measure certain points on your head. He or she will use a special pencil to mark the spots where electrodes will be placed on your scalp. Your scalp will be rubbed with a mild abrasive, and electrodes will be attached.
