An EEG is a test to detect problems in the electrical activity of the brain. For this test, electrical impulses from your brain, are read through electrodes attached to your scalp.The procedure is painless, and produces a pattern of impulses recorded on a disk or paper. During the test, the examinee may be asked to perform certain tasks, such as breathing deeply and rapidly for several minutes, look at a bright flashing light or sleeping.
