在一个外伤性脑内病变的病人,我们记录了两个连续的脑电图爆发抑制活动。在两次测量之间,患者的临床状况恶化。第一次脑电图显示对称的大脑半球间的爆发。然而,在第二次脑电图中,我们注意到从一个半球到另一个半球的同步性,但在相反的方向上是不同步的。我们提出了一个简单的模型,可以解释为什么爆发抑制活动的单向抑制比对称抑制更严重。
In a patient with traumatic intracerebral lesions, we recorded two subsequent electroencephalograms with burst-suppression activity. Between the two measurements, the clinical condition of the patient deteriorated. The first EEG showed symmetrical interhemispheric asynchrony of bursts. In the second EEG, however, we noted synchrony from one hemisphere to the other, but asynchrony in the opposite direction. We propose a simple model that can explain why one-way asynchrony of burst-suppression activity is prognostically more severe than symmetrical asynchrony.
