[The EEG characteristics in a lesion of different sections of the human caudate nucleus].
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.
