title: [Super-slow oscillations of cerebral biopotentials in patients with transient circulatory disorders in vertebral-basilar basin].
abstract: The paper deals with a study of 30 patients with transient disorders of circulation in the vertebro-basillar basin. Besides the routine methods of clinico-laboratorial examinations, for the first time in neurological practice a new method of electrophysiological registration was used: superslow fluctuations of the brain biopotentials. The patients were examined during the interattack period. According to the character of changes in the superslow brain activity the patients were divided into 3 groups. It was possible to establish that the characteristics of superslow fluctuations in the brain biopotentials correlates with the state of the activity of adaptive-regulative brain mechanisms. This condition is reflected in the frequency, duration and severity of transient vascular episodes. Such data permit to clarify some pathogenetical mechanisms in the development of transient disorders of cerebral circulation.
