title: [On the informative value of coherence analysis in clinical EEG studies].
abstract: Within the framework of discussion about the informative value of the method of coherent analysis, results of successful clinical application of this method of EEG processing in different morbid conditions are reviewed. Not denying the theses proposed by the opponent about the imperfection of methodological maintenance of the EEG coherent analysis and incompatibility of the results received with different software, the ways of overcoming these difficulties are specified. First of all, it is offered to unify procedural conditions of the technique. The thesis of the opponent that calculation errors are influenced by hypothetical "noise" (all signals of the environment) is regarded skeptically, as it could not be found in patients with "zero" coherence with the diagnosis of brain death. Some doubts are cast upon the prospect of replacement of the coherent analysis with an artificial envelope of the modulated groups of waves in assessment of synchronous processes of the brain. It is concluded that all technological and methodological problems of application of the EEG coherent analysis existing now can be overcome.
