Hyperventilation (HV) is an important activating procedure in clinical EEG. Paroxysmal HV slowing is associated with hypoglycemia and is common in children. Paroxysmal slowing in adults is sometimes interpreted as indicating cerebral instability or paroxysmal tendencies. We investigated the clinical
