国内对颅后窝病的EEG尚无专题综述,为了深入了解这方面的知识,特就此作一介绍。颅后窝各部位病变的EEG有共同特征,即Bagchi等及本人所报告的6个EEG深部特征:(1)前、后部或弥漫性双侧同步化δ、θ、α发放;(2)在类似区域之间有易变的半球间发放;(3)矢状旁的双侧前部与双侧后部发放的易变性;(4)矢状旁的一侧变化;(5)所有的阵发性电压增高或波率变慢的一侧半球加强;(6)前后的、易变的位相倒转。头二个特征更为重要。Small等将上述特征之一或更多种作为
Domestic EEG on the posterior fossa of the skull no special survey, in order to gain a better understanding of this knowledge, especially to introduce this. The EEG lesions in all parts of the posterior fossa share common features, namely the 6 deep features of EEG reported by Bagchi et al. (1) the distribution of δ, θ, α in the anterior, posterior or diffuse bilateral synapses; (2) Variable interhemispheric distribution between similar regions; (3) variability in the bilateral anterior and bilateral posterior sagittal; (4) lateral changes in the sagittal plane; (5) all Paroxysmal voltage increase or slow wave side of the hemisphere to strengthen; (6) before and after the volatile phase reversal. The first two features are more important. Small et al. Do one or more of the above features
