With domestic ND-161 16-channel EEG machine pictorial EEG: basic rhythm to 30-100μv9.5-10.5c / SA activity-based. Eyes closed evoked test: α wave suppression is not complete. Lead on both sides of the basic symmetry, the region appeared scattered and short-range 75-160μV6-7c / sθ rhythm; particularly prominent frontotemporal area. Hyperventilation induced test 23 seconds after the paroxysmal frontal paroxysmal 100-
