The EEG recordings of 41 patients with thalamic arteriovenous malformations (AVM) were studied by means of multivariate statistical analysis. In 16 patients the AVM were located in pulvinar, in 17 patients in the ventrolateral, in 4 patients in the medial, and in the remaining 4 patients in the anterior thalamic regions. Pathological EEG signs were visually classified and subjected to analysis of variance. The EEG signs were separated caused by the lesion localization. It was shown that the lesions in the posterior thalamus resulted in the alpha-rhythm suppression up to its total elimination. It was substituted for the bilateral local pathological activity in the posterior areas of the hemispheres. The diffuse beta-activity was observed. The ventrolateral and medial thalamic lesions led to the alpha-rhythm disorganization and its exaltation. The local slow waves were revealed in the sensorimotor cortical areas. The diffuse slow activity was observed as well as the signs of diencephalic irritation in the form of bilaterally synchronous bursts of activity in the alpha-theta range.
通过多变量统计分析研究了41例丘脑动静脉畸形（AVM）患者的脑电图记录。16例患者的AVM位于丘脑枕，17例位于腹外侧，4例位于内侧，其余4例位于丘脑前部区域。对病理性脑电图征象进行视觉分类并进行方差分析。脑电图征象因病变定位而有所不同。结果表明，丘脑后部的病变导致α节律抑制直至完全消失，被半球后部区域的双侧局部病理性活动所取代，观察到弥漫性β活动。丘脑腹外侧和内侧病变导致α节律紊乱及其增强，在感觉运动皮层区域发现局部慢波，还观察到弥漫性慢活动以及以α-θ范围内双侧同步活动爆发形式出现的间脑刺激征象。
