title: [The reflection of compensation processes in the structure of the EEG spatial-temporal relationships in patients with disordered brain regulatory mechanisms].
abstract: Studies of intercentral relations of electrical activity in the cerebral cortex of the patients with hypophysis tumours under the conditions of chronic (before operation) and acute (after tumour ablation, early post-operative period) influence of the focus on the regulatory brain systems allowed to reveal definite changes of spectral-coherent EEG characteristics, reflecting the functional state of the cerebral adaptive-compensatory apparatus. It has been shown that reciprocal character of changes of various forms of the brain electrical activity and their intercentral relations is one of manifestations of development of the processes of cerebral compensation. At the same time, global fall of the EEG intercentral relations indicating the disintegration of the cerebral functional connections, reflects a loss of CNS compensatory mechanisms. The revealed EEG-characteristics at the present time are applied in Burdenko Institute of Neurosurgery for diagnostic-prognostic estimation of the brain functional state in patients during pre- and post-operative period.
