| Summary: | Purpose of the study - to reveal the relationship of autonomic homeostasis with interhemispheric asymmetry of the brain in young residents of the Arctic zone of the Russian Federation. Materials and methods. The study of cerebral energy processes and interhemispheric asymmetry was carried out by registering the DC-potential level of the brain and calculating the interhemispheric gradient (Td-Ts) on a 5-channel hardware-software diagnostic complex "NeuroKM" in 63 young people of working age (30-34 years old), born and permanently residing in the Arctic zone. The study of autonomic homeostasis included the study of the frequency parameters of heart rate variability at rest and during exercise - a passive orthostatic test using the VNS-spectrum diagnostic complex (Neurosoft LLC). Statistical data processing was carried out using the SPSS Statistics 26 software. Research results. In northerners with different types of hemispheric dominance of cerebral energy processes, the sex characteristics of autonomic homeostasis were revealed. At rest, in both study groups, the activity of the parasympathetic division of the autonomic nervous system in the regulation of the heart rhythm predominates. In "left hemispheric" men and "right hemispheric" women, there is an insufficient reactivity of the parasympathetic division of the autonomic nervous system in response to the orthostatic test and an increase in sympathetic activity. In men with right hemispheric asymmetry and women with left hemispheric dominance, a more pronounced vagal activity with normal parasympathetic reactivity in response to load and preservation of the reserve of parasympathetic regulation is observed. Conclusion. Thus, the most optimal vegetative homeostasis is observed in men with right hemispheric dominance and women with left hemispheric asymmetry of cerebral energy exchange. |
