The study was aimed to reveal the characteristic features of EEG in 343 patients with caudate lesions depending on the localization of the pathological process (arteriovenous malformation, AVM). Methods of multivariate statistics were applied. It was shown that lesions in the body of the caudate nucleus (NC) were accompanied by the alpha-rhythm suppression up to its complete disappearance at the side of AVM and at the opposite side. Lesions in the head of NC were characterized by diffuse cortex irritation and local changes of the irritative character in the fronto-posterior and central regions at the side of AVM. Applied methods of EEG analysis made it possible to separate the influence of AVM localization within the limits of NC from other pathological factors accompanying it and to show the role of different parts of NC in formation of brain bioelectrical activity.
本研究旨在揭示343例尾状核病变患者脑电图（EEG）的特征，这些病变取决于病理过程（动静脉畸形，AVM）的定位。应用了多元统计方法。结果显示，尾状核体部病变时，AVM侧及对侧的α节律抑制直至完全消失。尾状核头部病变的特征是弥漫性皮质激惹以及AVM侧额、中央和后头部区域的局部刺激性改变。所应用的EEG分析方法能够区分AVM在尾状核范围内的定位影响与伴随它的其他病理因素，并显示尾状核不同部位在脑生物电活动形成中的作用。
