title: [Spectral analysis of the EEG in patients with cerebral contusions and traumatic intracranial hematomas].
abstract: The authors subjected to a mathematical analysis 80 electroencephalograms registered in 20 patients with contusional foci andintracranial hematomas, verified during surgical operations. In order to evaluate the peculiarities of the EEG spectrograms an adaptive system of filtration was proposed which was based on an approximation of the assessment of the spectral density. The used method with the aid of computers permitted to detect the characteristic disturbances of the frequency spectrum in the EEG which had a topical and differential diagnostical significance for patients in the acute period of a severe brain injury.
