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.

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.

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. Keywords: functional state of the central nervous system, Internet addiction, visual-motor reactions, students. Современное общество уже невозможно представить без Интернета. 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.

The purpose of the study was to determine the neurodynamic and psychological properties of elite cyclists concerning the level of mobilizationin the reaction to the moving object. In order to determine the neurodynamic properties of athletes we used the diagnostic complex "Diagnost-1". The reaction to the moving object was used to monitor and predict the functional state of the central nervous system of athletes, to assess thespeed and accuracy of the response, the excitation/inhibition ratio, and the balance of nervous processes. Moreover, we have analyzed the forceand functional mobility of nervous processes, the sensorimotor activity, namely the dynamics of nervous processes, the efficiency and speed ofboth the simple sensorimotor reaction, and the simple and complex sensorimotor choosing reaction, the sensorimotor asymmetry index, and otherparameters. Hans Eysenck's Personality Inventory (EPI), the State-Trait Anxiety Inventory by C. Spielberger (adapted by Y. Hanin) and the Luscher color test allowed determining individual typological characteristics and the psycho-emotional state of athletes. The results of the reaction to the moving objects revealed differences between cycling athletes with high, medium and low mobilization rates. The most optimal functional state of the central nervous system in terms of the reaction to the moving object was specific to the cyclists with the low level of mobilization. Athletes with a high level of mobilization did not demonstrate significant differences in the reactions to the moving objects, but differed the higher stability in the complex sensory-motor choice reaction. Athletes with the medium level of mobilization in the reaction to the moving objects were characterized by the lowest level of State Anxiety in combination with a reduced functional state of the central nervous system. Thus, the higher efficiency of sensorimotor response was detected in the athletes with the high and low mobilization level in the reaction to moving objects.

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.

The features of production factors established at the main workplaces of shoe production are considered. The materials on the results of the study of the functional state of the central nervous system of women workers of shoe production in the dynamics of the working day are presented. The level of functional state of the central nervous system was determined by the speed of visual and auditory-motor reactions, installed using the universal device chronoreflexometer. It was revealed that in the body of workers of shoe production there is an early development of inhibitory processes in the central nervous system, which is expressed in an increase in the number of errors when performing tasks on proofreading tables. It was found that the most pronounced shift s in auditory-motor responses were observed in professional groups, where higher levels of noise were registered in the workplace. The correlation analysis showed a close direct relationship between the growth of mistakes made in the market and the decrease in production. An increase in the time spent on the task indicates the occurrence and growth of production fatigue.Funding. The study had no funding.Conflict of interests.

Toxicity and hazard assessment of dioctyl terephthalate (DOTP) was performed in acute, subacute, and chronic experiments, and its principal toxicometry parameters were determined.It was found that on single exposure DOTP exhibits low toxicity and hazard. No resorptive and irritant effects on skin and mucous membrane of eyes were detected in animal experiments. The single inhalation exposure threshold limit value was set at 300 mg/m3, based on the results of monitoring of the functional state of the central nervous system and myocardium and hematological parameters.Thirty-day subacute experiments (oral administration, inhalation exposure, and skin applications) revealed no accumulation of the compound.Four-month chronic exposure to DOTP aerosols (concentration 96,8 mg/m3) caused disorder of the functional state of the central nervous system and myocardium, changes in the hematological and biochemical parameters, gas and acid-base status of the blood, and morphological changes in the lungs and heart. Embryotoxic, genotoxic and gonadotoxic effects were not detected.The chronic inhalation exposure threshold limit value for DOTP (Limch) was set at 18,6 mg/m3, and the concentration of 3,4 mg/m3 was found to be ineffective.The maximum allowable concentration of DOTP in the air of the working area was set at 3,0 mg/m3, hazard class 3.
