What to Expect

Your head will be measured and electrodes are placed on the scalp with a cream-like substance. You will then be asked to lie still, be relaxed and comfortable. During the test you may be asked to take repeated deep breathes (hyperventilation) or you may be shown a strobe light that flashes at different speeds (photic stimulation). Drowsiness and sleep are encouraged during the test.
