The study focuses on the lability and adaptability of the central nervous system of residents of Moscow and Moscow region aged 65 and older. All examinees regularly practised various types of physical activity, such as Nordic walking, cycling, Qigong gymnastics, etc. The functional state of the central nervous system of the examinees was studied using the Psychophysiologist hardware-software system by determining simple visual-motor reaction (SVMR), complex visual-motor reaction (CVMR), reaction to a moving object (RMO). Based on the analysis of speed and stability of sensorimotor reactions in response to light stimuli and moving object we made an express-evaluation of the level of functional state of the central nervous system, sensorimotor reactions, quality of activity, balance of inhibition and excitation processes. As a result of the study, the optimal level of CNS functioning was registered in most of the examinees. Activation of the central nervous system in the majority of the examinees is at an average level, the average level of operative efficiency is noted. The results of the study indicate a shift in the balance of nervous processes in the examinees towards inhibition.

The life of any modern society without the Internet is impossible. Every year the number of Internet users is increasing, as men and women of all ages and nationalities surf the net. However, along with the advantages, there are also negative moments of worldwide Internet growth, e.g. Internet addiction. Many adolescents are becoming netaholics, and it is evident that the Internet undermines their health. The aim of the study is to determine the functional state of the central nervous system (CNS) in students with various online behavior patterns according to a simple visual-motor reaction. Materials and Methods. The authors examined 202 students, aged 12–17, living in the city of Abakan (Republic of Khakassia). We used Chen Internet Addiction Scale (CIAS) adapted by V.L. Malygin and K.A. Feklisov to determine the online behavior pattern. A simple visual-motor reaction test was used to assess the functional state of the central nervous system. The test was performed on the Psychophysiological testing device-1/30 “Psychophysiologist”, a hardware-software complex. Nonparametric statistics was used for data processing: Pearson’s chi-square test was applied for qualitative indicators and the Mann–Whitney U-test – for quantitative ones. Results. The data obtained showed that a good functional state of the central nervous system prevails in students with various online behavior patterns. At the same time, teenagers-netaholics demonstrated lower indicators in the sensorimotor test in comparison with students with adaptive and non-adaptive Internet experience. Netaholics showed a decrease in concentration, attention span (accuracy and stability) and retardation (speed of response). Conclusion. Our findings indicate that despite a good functional state of the central nervous system predominance of CNS inhibition processes, fatigue, a decrease in mental performance and cognitive activity are peculiar to students-netaholics.

С каждым годом количество его пользователей увеличивается, в деятельность в сети Интернет вовлекаются все возрастные слои населения. Но наряду с достоинствами имеет место и негативное последствие распространения Интернета по миру – развитие сверхувлеченности сетью Интернет (интернет-зависимости), которая наиболее часто возникает в подростковом возрасте, отрицательно сказываясь на здоровье подростков. Цель. Определить особенности функционального состояния центральной нервной системы (ЦНС) у школьников с различными видами онлайн-поведения по параметрам простой зрительно-моторной реакции. Материалы и методы. Обследовано 202 школьника в возрасте 12–17 лет, проживающих в г. Абакан (Республика Хакасия). Для определения вида онлайн-поведения применяли адаптированную В.Л. Малыгиным и К.А. Феклисовым шкалу интернет-зависимости Чена (тест CIAS). Для оценки функционального состояния ЦНС использовали тест простой зрительно-моторной реакции с помощью аппаратно-программного комплекса УПФТ-1/30 «Психофизиолог». Статистическую обработку данных проводили с применением методов непараметрической статистики: критерия χ2 Пирсона для качественных показателей и U-критерия Манна–Уитни для количественных. Результаты. Полученные данные показали, что у школьников с различными видами онлайн-поведения преобладает удовлетворительное функциональное состояние ЦНС. При этом среди школьников с патологическим пользованием Интернетом (интернет-зависимостью) имеется тенденция к ухудшению значений по отдельным показателям сенсомоторного теста по сравнению со школьниками с адаптивным и неадаптивным пользованием Интернетом, что проявляется снижением концентрации и устойчивости внимания (по уровню безошибочности и стабильности), замедлением реакций (по уровню быстродействия). Выводы. Результаты исследования указывают на преобладание процессов торможения в ЦНС, состояние утомления, снижение психической работоспособности и когнитивной деятельности у школьников с интернет-зависимостью, несмотря на удовлетворительное значение функционального состояния ЦНС. Ключевые слова: функциональное состояние центральной нервной системы, интернет-зависимость, зрительно-моторные реакции, школьники.

Aim. The Federal State Educational Standard of Higher Education prescribes providing the educational process in accordance with the individual and typological features of students. The nature of adaptation shifts in students depends on ethnic, ecological, and morphological indicators determining the functional status of the body. Its functional status and functional abilities conditioned by academic and professional activities are determined by the cerebral process, which influences the efficiency of adaptation and cognitive performance in general. The article deals with studying the features of psychophysiological potential in Russian and Kazakh first-year female students during their adaptation to studying at the pedagogical university. Materials and methods. We conducted the diagnostics of the functional status of the central nervous system and cognitive performance in first-year female students at pedagogical universities. The average age of participants was 17.9 years. The total sample (n = 120) consisted of the Russian and Kazakh students living in Kostanay (Kazakhstan) and Chelyabinsk (Russia). A simple eye motor response (SEMR) and a complex eye motor response (CEMR) to a light stimulus were measured with the NS-Psychotest equipment. The calculated data are the following: the functional status of the system; response stability; level of functional abilities. These data were used as a basis for the assessment of cognitive performance in the participants of the study. Results. The results obtained characterize the neuro-dynamic basis of first-year students’ adaptation expressed in the average level of CNS activity, mobility of nervous processes, and optimal functional abilities. In the conditions of the average intragroup expression of the functional criteria of the central nervous system better cognitive processes for the processing of sensory information were revealed in students from Chelyabinsk compared to Kostanay. Conclusion. The analysis of the data obtained revealed the regional specifics of the average values of chronoreflexometry in first-year students, namely a significantly higher level of neural interaction and sensorimotor processing in first-year students from Chelyabinsk.

Interhemispheric functional asymmetry was studied in students of Khanty-Mansiysk State Medical Academy and Kurgan State University. The diff erences in the activation of the cerebral hemispheres in young people studying in diff erent climatogeographic conditions, depending on gender, were determined. Male Northerners demonstrated a symmetrical activation profi le of the large hemispheres. In Kurgan young men, the predominance of right-hemisphere activity was determined by the speed of a simple visual-motor reaction and the functional level of the nervous system. In the groups of girls, a large activation of the right hemisphere was observed in Northerners by the duration of the latent reaction period and the functional level of the nervous system, and in KSU students by all parameters of a simple visualmotor reaction.

The purpose of this research was to analyse the functional state of the central and autonomic nervous systems in young emergency physicians working in the northern region. Materials and methods. We examined 33 emergency physicians of a multidisciplinary hospital in Khanty-Mansi Autonomous Okrug – Yugra aged 25 to 43 years (19 men and 14 women). The functional state of the central nervous system (CNS) was assessed using the method of simple visual-motor reaction (SVMR) and criteria developed by T.D. Loskutova – system’s functional level (SFL), reaction stability (RS) and level of functional abilities (LFA) – as well as attention stability, working memory and Whipple’s accuracy index. The state of autonomic regulation was evaluated according to the dynamics of heart rate variability (HRV) at rest and during active orthostatic test (AOT). Results. We found that male emergency physicians have higher rates of psychomotor reactions, SFL, RS, and LFA than their female colleagues. SVMR showed pathological reactions of the CNS in subjects of both sexes. The body’s adaptive capabilities due to autonomic regulation were preserved in most emergency physicians. However, a pathological response to AOT was found in both men and women. The pathological basis for impaired autonomic regulation and the development of maladaptive reactions in the subjects was a deterioration of the current functional state of the body, excessive activation of the sympathoadrenal system and a decrease in parasympathetic regulation. Responses to AOT in male emergency physicians were accompanied by a decrease in the total power (TP) of the HRV spectrum by 24.7 %, and an increase in low frequency (LF) to high frequency (HF) ratio by a factor of 2.6; while in female doctors, by a decrease in TP by 11.5 % and an increase in LF/HF ratio by a factor of 1.7. The median of 30/15 coefficient was 1.48 for men and 1.45 for women. Thus, in the course of professional selection of doctors to provide emergency care under unfavourable climatic conditions of the North, it is advisable to conduct a comprehensive examination of the functional state of the central nervous system and autonomic regulation to identify a risk group with impaired adaptation mechanisms.

Background. The function of the central nervous system in adolescents reflects the complex influence of climatic and social conditions, as well as morphofunctional lability characteristic of puberty. Studying the functional state of the central nervous system in adolescents living at high latitudes is important for forming a region-dependent norm of the functional state of the body. Aim. The paper aims to reveal the features of sensorimotor integration as an indicator of the functional state of the central nervous system in 11–14-year-old students living in the North. Materials and methods. 88 schoolchildren from Surgut (46 males and 42 females) aged 11–12 years (1 group, n = 33) and 13–14 years (2 group, n = 55) were examined. Psychophysiological testing was carried out with the help of the NS-Psychotest hardware and software (Neurosoft, Ivanovo). The following methods were used: simple visual and motor reaction, complex visual and motor reaction – choice reaction. Mathematical and statistical processing was carried out in Microsoft Excel and Statistica 10.0. Results. Sex-related differences in neurodynamic data were revealed: average parameters of boys of both groups in comparison with girls are characteristic of a more active and mobile central nervous system. The functional state of the central nervous system in males is higher than that of females in both age groups, though, sensorimotor responses of females are more stable. Age-related improvements in sensorimotor integration were noted due to improved cerebral processing of sensory information by reducing latency time of sensorimotor responses. In males, depending on age, there was a tendency to negative changes in the functional state of the central nervous system. Conclusions. The results obtained describe the average level of activation and a high level of functional mobility of nervous processes in all adolescents. The average level of the functional state of the central nervous system reflects the optimal functional capabilities of the participants, which is the basis for effective psychophysiological adaptation to living conditions and educational activities.

Introduction.During the study, we tried to find out whether the temporal characteristics of sensory-motor response can reflect the typological properties of the central nervous system. Such research is essential to reveal the mechanisms of development of higher mental functions and mental capacity.Purpose.To establish the relationship between the speed characteristics of visual-motor reaction different complexity and individual-typological properties of the central nervous system.Methods.Individual differences of sensorimotor reaction and the properties of the main nervous processes were determined by the method of M. V. Makarenko [8] using the computer system "Diagnost-1". 32 teenagers aged 10-11 were examined. During the study, the indicators of latent periods of simple (SVMR) and complex visual-motor reactions of choice (RC1-2, RC2-3), functional mobility of nervous processes (FMNS) were investigated. Results.Speed characteristics of simple (SVMR) and complex visual-motor reactions of choice of one (RC1-3) and choice of two (RC2-3) excitatory and inhibitory signals were studied in order to 202177use them to assess individual typological properties of the central nervous system (CNS) in adolescents 10-11 years old. There is no evidence of a relationship between the rate of SVMR with different levels of functional mobility (FMNS) of nervous processes in adolescents 10-11 years old.The reaction rate did not differ statistically and was the same in representatives with high, medium and low levels oftypological properties of nervous system. The results of the correlation analysis between SVMR and FMNP were r = 0.13 (p = 0.59), which indicated no relationship between them. The relationship of sensorimotor response time with individual-typological features of the CNS was established in complex information differentiation RC2-3. The temporal characteristics of RC2-3 were dependent on the individual-typological properties of the CNS.The reaction rate of RC2-3 was higher in adolescents 10-11 years old with high levels of -3 were r = 0.35 (p = 0.034).The results show that the velocity characteristics of complex neurodynamic acts, in contrast to simple ones, can be used as quantitative characteristics of the typological properties of the CNS.Originality.The results of our research may be evidence that the indicator RC2-3 can be used as an additional informative criterion for assessing the individual-typological properties of the higher parts of the central nervous system.Conclusion. The temporal characteristics of SVMR and RC1-3 cannot be considered as informative criteria for assessing the individual-typological properties of CNS in adolescents 10-11 years. Time characteristics of RC2-3 differentiation reactions can be used as additional indicators for assessing the individual-typological properties of higher nervous activity in adolescents 10-11 years, namely, the level of functional mobility of nervous processes.Key words:processing of information of various complexity, speed characteristics of simple reactions, motor acts of choice and differentiation, individual-typological properties, functional mobility of nervous processes
