The article discusses the probable role of many factors that determine the individual variety of the neurophysiological mechanisms that provide the opportunity to learn and use fluently two or more languages. The formation of the speech function is affected by both the general factors for bilinguals and monolinguals, as well as by the specific(More)
Changes in systemic brain activity under the influence of classic music (minor and major music) were studied based on two groups of healthy children aged five to six years (n = 53). In 25 of the children studied, the Luscher test showed the increased level of anxiety, which significantly decreased after music therapy sessions. Bioelectric cortical activity(More)
We report here data on a number of systematically recorded phasic EEG phenomena during the sleep–waking cycle, along with data on the heterogeneity of the EEG stages of sleep forming sequential sleep macrocycles in humans. These transient EEG changes quite often showed a tendency to periodicity, especially at the initial stages of sleep and in transitional(More)
Adolescence is characterized by an intense formation of interregional interaction of cortical areas. In this period, the activity of deep brain structures is significantly reorganizing and cortical-subcortical interaction is augmenting. Our objective was to assess the pattern of changes in the spatial structure of brain bioelectric potentials with age and(More)
Adolescence is characterized by an intensive formation of inter-regional cortical fields interaction, in this period significantly reorganized the activities of deep brain structures and cortical-subcortical interaction are enhanced. Our objectives were to evaluate the nature of changes in the spatial organization of brain bioelectric potentials with age(More)
The present article is an attempt to perform a conceptual clinical and physiological analysis of a large spec- trum of sleep-related phenomena called parasomnias in children, based on data from three independent in- stitutions. Parasonmias appear in the process of falling asleep, at the time of sleep stage changes, and upon awakening. They are common for(More)
The present article is an attempt to perform a conceptual clinical and physiological analysis of the large spectrum of sleep-related phenomena called parasomnias in children, based on data from three independent institutions. Parasomnias appear in the process of falling asleep, at the time of sleep stage changes, and upon awakening. They are common for both(More)
This study presents data on some phasic EEG phenomena regulary recorded during sleep - wakefulness cycle and heterogeneity of EEG sleep stages forming consecutive human sleep macrocycles. These short-term EEG changes quite often tend to periodization, especially during initial sleep-stages and transitive states (sleep microcycles). An attempt was made to(More)
