In some instances, a person may undergo a 24-hour EEG. They may ask you to lie still, close your eyes, breathe deeply, or look at stimuli (such as a flashing light or a picture).ĭuring the test, very little electricity passes between the electrodes and your skin, so you’ll feel very little to no discomfort.

If an EEG does not produce any abnormalities, stimuli such as strobe lights, or rapid breathing may be added to help induce any abnormalities.
