20多年前,开始测量人的诱发电位,记录意识清醒状态下人脑的电活动,这对阐明精神病患者的脑机能障碍,提供了新的途径。我们知道,大多数精神分裂症患者常有低波幅、失同步以及快而不明显的α节律的脑电图。这种脑电图被称为“起伏(choppy)活动。大约60％的精神分裂症患者呈现上述所谓的“起伏”电活动。可是,这些发现尚 More than 20 years ago, the measurement of the human evoked potential and the recording of the brain’s electrical activity in conscious states provided a new avenue to elucidate the brain dysfunction in psychiatric patients. We know that most people with schizophrenia often have low amplitude, loss of synchronization and fast, unobvious alpha-rhythm EEG. This electroencephalogram is called “choppy” activity and about 60% of schizophrenic patients exhibit the so-called “undulating” electrical activity described above.
