[Study of the associative activity of schizophrenic patients by the technic of remote synchronization of cortical biopotentials]. / Issledovanie assotsiativnoi deiatel'nosti bol'nykh shizofreniei metodom distantnoi sinkhronizatsii biopotentsialov kory golovnogo mozga.

To reveal physiological correlates of the schizophrenic thinking peculiarities associated with impaired mechanisms of information selection, spatial synchronization of the cortical biopotentials was studied in 10 healthy probands and 9 patients with continuously progressing schizophrenia. Both the healthy probands and the patients were asked to solve problems of comparing notions in situations where standard or non-standard criteria for the solution could be chosen. The bioelectrical activity was recorded at 48 cortical sites with subsequent estimation of the cross-correlation interconnections between the EEGs. It was found that in the solution of problems with the use of standard criteria the spatial-temporary organization of the biopotentials differed but little in the healthy probands and the patients, whereas in the solution of problems for which secondary, latent features of the subjects were required, these differences were rather marked in a number of characteristics, such as the general level of the synchronism, the character of interhemispheral asymmetries, the topographic distribution of the biopotential synchronization. The data obtained are discussed in the light of the present-day concepts on the functional specialization of the hemispheres.

[Clinico-electrophysiologic characteristics of non-process personality changes and schizophrenia in adolescence]. / Kliniko-élektrofiziologicheskaia kharakteristika neprotsessual'nykh izmenenii lichnosti i shizofrenii v podrostkovom.

The paper deals with a study of spatial organization in the biological processes during their toposcopical registration. These studies were necessary to determine the clinical and electrophysiological criteria for the differential diagnosis of schizophrenic patients and nonprocess personality deviations in adolescency. The data obtained demonstrated several differences, as shown by bioelectrical indices, in the intrahemispheric, interhemispheric, intracortical and cortical-subcortical interrelationships in the general system of functional contacts. On the basis of literary and personal experience certain assumptions are made, related to the differentiated influence of each of the links in the dynamic organization of brain activity on the character of psychopathological signs.

[Clinical features of several variants of schizophrenia in adolescence. I]. / K voprosu o klinicheskikh osobennostiakh nekotorykh variantov shizofrenii v podrostkovom vozraste (soobshchenie I).

A total of 87 schizophrenic patients (39 boys and 48 girls), with a psychopathlike syndrome and deviant behaviour were examined. On the basis of the clinical picture and type of development of the disease, 2 groups of patients (from 14-18 years) were distinguished. The first group included patients who by their clinical traits belonged to heboid schizophrenia and were observed in the framework of a one-attack shiftlike development of the process. In the second group the psychopathlike syndrome was expressed in the presence of increasing personality changes, while the development of the process was a sluggish type.

[Clinico-psychopathologic features of non-process forms of deviant behavior in adolescence]. / Kliniko-psikhopatologicheskie osobennosti neprotsessual'nykh form deviantnogo povedeniia v podrostkovom vozraste.

Clinico-psychopathological traits of non-process forms of deviant behaviour in adolescents were studied in the framework of pathological personality formation. Two variants in the development of the disease were distinguished: favourable and unfavourable. Some differential diagnostic criteria are outlined which permit to delineate this form of borderline pathology from a debut of schizophrenia in adolescency. The study includes a consideration of the disturbed system of relationships of the personality in the adolescents examined.
