Using scalp and depth electroencephalography (EEG), we examined the relationship between the surface EEG activity and abnormal EEG discharges in the ipsilateral hippocampus in order to study the neuronal connection between the two cerebral regions. Ictal EEG was divided into 4 groups: 1) unitempo-ipsilateral-bifrontal slow waves, 2) unitempo-ipsilateral-bilateral slow waves, 3) bilateral slow waves, and 4) bilateral slow waves with repetitive spikes. Abnormal depth EEG activity in the hippocampus was classified into paroxysmal discharges and recruiting rhythms. Ictally and interictally, repetitive sharp waves or spikes in the unilateral hippocampus were associated with sharp waves or spikes in the ipsilateral temporal region. These findings suggest that the ipsilateral projection of seizure activity originating in the unilateral hippocampus is dependent upon the function of the subiculum.
我们使用头皮和深度脑电图（EEG），研究了同侧海马体中表面EEG活动与异常EEG放电之间的关系，以探究两个脑区之间的神经元连接。发作期EEG分为4组：1）单时相-同侧-双额慢波，2）单时相-同侧-双侧慢波，3）双侧慢波，4）伴有重复棘波的双侧慢波。海马体中异常深度EEG活动分为阵发性放电和募集节律。在发作期和发作间期，单侧海马体中的重复锐波或棘波与同侧颞区的锐波或棘波相关。这些发现表明，起源于单侧海马体的癫痫活动的同侧投射依赖于下托的功能。
