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.

In uncomfortable conditions, high academic load leads to adaptive changes in medical students. The functional status and level of functional capacities in students determines the effectiveness of adaptation and cognitive performance. Aim. The article aims to identify the features of the functional status of the central nervous system using the data of simple visual-motor reaction in medical students studying in the northern region. Materials and methods. 95 students were examined, 51 females and 44 males. The average age was 19.62 ± 1.57 years. The indicators of variational chronoreflexometry were determined through the data of simple visual-motor reaction. The level of functional capacities of the central nervous system, the stability of reactions, and the functional level of the system were calculated. The study was carried in accordance with the method proposed by M.P. Moroz (Express-diagnostics of the functional status and human performance). Results. It was established that in most cases the functional status of the central nervous system in medical students corresponded with reduced and slightly reduced mental performance. Simple visual-motor reaction time in male and female students was 280.47 ± 2.34 ms and 278.09 ± 2.92 ms, respectively. Significant differences were not revealed among the studied groups. Conclusion. The functional status of the central nervous system in medical students of the Middle Ob region is characterized by high neuropsychic tension, increased fatigue, decreased working capacity, weakened attention and concentration.

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.

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

 Objective: The goal of the research is studying the functional changes in the central nervous system against the background of intoxication with the minimum dosages of gasoline, benzene and acetone.Methods: The research was performed on 45 white mice divided into 3 groups; each group received corresponding hydrocarbon in the exposure chamber by inhaling. The functional state of the CNS was assessed with a complex of integral tests: By summation of subliminal pulses, the ability of animals to restore rectilinear movement after centrifugation, by the tone of skeletal muscles, and by the activity of muscle static work.Results: The durations of the narcosis phases in case of acute inhalation poisoning are different for all studied substances. The study of the functional changes in the CNS on the background of intoxication with low dosages has revealed that at the first exposure to benzene for activating the motor reaction the required number of electric pulses from the outside increases, the muscle tone increases, the ability to static work reduces, and the time for rectilinear movement and “animal hypnosis” increases. At the same time, on the background of intoxication during the fifth exposure, a decrease is observed in the number of electric pulses from the outside for activating the motor reaction, the muscle tone remains increased, the ability to static work is reduced, and the time of “animal hypnosis” is shorter than that during the first exposure.Conclusion: Against the background of the repeated use of small doses of benzene, the CNS adapts to the action of the toxic factor. With that, the ability of the CNS to sum the subliminal pulses, the cholinergic innervation of the skeletal muscles tone and other integral tests during the fifth exposure change less than during the first exposure.

Introduction. The purpose of the study was to assess the hygienic impact of classes with using an interactive whiteboard and an interactive table on the functional state of the body of preschool children aged 6-7 years. Material and methods. The results of studies of the impact of classes using interactive equipment in kindergarten on the functional state of the body of children aged 6-7 years. The interactive whiteboard was used in all classes (two or three) during the day. Continuous duration of its use at each session did not exceed 5 minutes, in total - 15 minutes during play activities used the interactive table which lasted up to 10 min. Results. The comparative analysis of the results of the studies did not reveal any differences in the indices of fatigue and psycho-emotional state of children in the response to developmental activities with and without the use of interactive equipment. The expressed activating influence of occupations with use of the interactive equipment on the activity of the central nervous system is established. This was manifested in a significant increase in the speed of complex sensorimotor responses and a decrease in the probability of an error. Discussion. In our opinion, the approximate response to the novelty, bright and attractive form of information presentation with the interactive equipment lead to the functional mobilization of brain structures involved in the analysis of information, followed by a more pronounced concentration of attention, creates an optimal tone of the central nervous system, providing ease and speed of lockings and functioning of nerve connections underlying learning.

Genetic Contributions

Recent remarkable advances in genetic technologies have allowed for the identification of genetic factors potentially related to a predisposition to elite athletic performance. Most of these genetic variants seem to be implicated in musculoskeletal and cardiopulmonary functions. Conversely, it remains unclear whether functions of the central nervous system (CNS) genetically contribute to elite athletic traits, although the CNS plays critical roles in exercise performance. Accumulating evidence has highlighted the emerging implications of CNS-related genes in the modulation of brain activities, including mental performance and motor-related traits, thereby potentially contributing to high levels of exercise performance. In this review, recent advances are summarized, and future research directions are discussed in regard to CNS-related genes with potential roles in a predisposition to elite athletic traits.
