Main scientific achievements
In the process of pubertal development, significant factors reflecting the maturation process of the bioelectrical activity of the brain are a diffuse drop in the amplitude of all rhythms and the strengthening of the caudal alpha rhythm focus against the background of suppression of the anterior-central alpha focus. In neurotic disorders against the background of a delay in the fall of the amplitude of the rhythms and the formation of the caudal focus of the alpha rhythm, the formation of the theta rhythm is observed in the anterior-central regions indicating the increased activity of the septo-hippocampal system. In the preschool period, the most pronounced changes in boys, in comparison with girls, are leveled at the senior school age, and with the further development this dynamics persists.
The observed restructuring of the bioelectrical activity of the brain (EEG) from mature age to older reflects the emerging imbalance in non-specific systems: an increase in the level of activity, on the one hand, the synchronizing effects of the septo-hippocampal system, and on the other, the ascending premises of desynchronizing mechanisms.
The influence of the weak geomagnetic disturbance of the Earth on the functional state of the brain of women 50-60 years old is most likely mediated through the effect on the central regulating apparatus of the brain, among which the leading role belongs to the structures of the limbic-reticular complex activating and deactivating the links of nonspecific systems. On days of weak geomagnetic disturbance compared to days with a calm geomagnetic environment, in the group of older women compared to women of mature age, the EEG structure reflects a less optimal variant of the distribution of rhythm characteristics over the cortical areas when solving an arithmetic problem.
