ONE-WAY ASYNCHRONY OF BURST-SUPPRESSION ACTIVITY

In a patient with traumatic intracerebral lesions, we recorded two sub sequent electroencephalograms with burst-suppression activity. Between the two measurements, the clinical condition of the patient deteriora ted. The first EEG showed symmetrical interhemispheric asynchrony of b ursts. In the second EEG, however, we noted synchrony from one hemisph ere to the other, but asynchrony in the opposite direction. We propose a simple model that can explain why one-way asynchrony of burst-suppr ession activity is prognostically more severe than symmetrical asynchr ony.
