Blood oxygenation level dependent (BOLD) response related to interictal activity was evaluated in a patient with post-traumatic focal epilepsy at repeated continuous electroencephalogram (EEG)-functional magnetic resonance imaging examinations. Lateralized interictal EEG activity induced a main cluster of activation co-localized with the anatomical lesion. Spreading of EEG interictal activity to both frontal lobes evoked bilateral clusters of activation indicating that topography of BOLD response might depend on the spatial distribution of epileptiform activity.
在一名创伤后局灶性癫痫患者的重复连续脑电图 (EEG)-功能磁共振成像检查中，评估了与癫痫间期活动相关的血氧水平依赖 (BOLD) 反应。偏侧性癫痫间期 EEG 活动诱导了一个与解剖病变共定位的主要激活簇。癫痫间期 EEG 活动向双侧额叶扩散引起双侧激活簇，表明 BOLD 反应的拓扑结构可能取决于癫痫样活动的空间分布。
