由一个区域来的重复性活动的现象,脑电图可以表示一种局限性(部分性)的癫痫发作。这一现象不同于脑电图的背景节律,并且不是由于警觉水平改变所致。这种持续活动的形态可能是连续的棘波和尖波成类正弦波(Sinusoidal)。大概是Jasper1949)和Jaser 等(1951)最早提出自发活动减少表示癫痫发作。Klass(1975)发现116例部分性癫痫病人中25%的病人自发活动减少。为了进一步确定局限性或区域性发作活动的形态,作者观察了66例自发地发生部分性癫痫的病例。
The phenomenon of repetitive activity by a region, EEG can represent a limited (partial) seizures. This phenomenon is different from the background rhythm of EEG, and not due to changes in the level of alertness. This pattern of sustained activity may be continuous spikes and spikes into a class of sinusoids. Probably Jasper1949) and Jaser et al. (1951) first proposed a decrease in spontaneous activity indicating seizures. Klass (1975) found that spontaneous activity decreased in 25% of 116 patients with partial epilepsy. To further determine the limitations or the pattern of regional seizures, the authors observed 66 cases of spontaneous partial epilepsy.
