Chronoreflexometric characteristics of the mental performance of children of primary school age - the natives of the Middle Ob were based on the statistical analysis of the latent period of time of a simple visual - motor responses. The results of a survey showed that the functional state of the nervous system of surveyed children ofprimary school age was at “reduced” and “greatly reduced” level of mental performance. This state is characterized by a weakening of attention, a sharp deterioration in time and accuracy parameters of activity and a significant decrease of efficiency on the whole.

Objective: to analyze the neurodynamic indicators of the sensorimotor response of primary school age children with orthophoria and heterotropia. Material and methods. 51 children (102 eyes) aged 6-11 were examined. 2 groups that could be compared in terms of age and sex were formed. The first group consisted of 20 patients (40 eyes) with orthophoria associated with moderate hypertropia of Hm 3.5 (2.3; 5.3) diopters, the second group included children with concomitant convergent strabismus associated with moderate hypertropia of Hm 4.25 (2.0; 6.5) diopters - 31 patients (62 eyes). To study the properties of the nervous system (NS), the computer appliance «NS-Psychotest» (LLC «Neurosoft», Ivanovo, http://neurosoft. com/ru) was used. The neurodynamic indicators of the sensorimotor response were identified with the techniques «Simple Visual Motor Response» (SVMR), «Discrimination reaction» (DR), «Moving Object Response» (MOR), «Critical Flicker-Fusion Frequency» (CFF). Results. Concomitant strabismus in the children of the second group reliably leads to an increase in the time of SVMR, DR by 65.5 ms and 42.4 ms, respectively (p < 0.05), in comparison with the group of the children with orthophoria. The difference between the indices of DR and SVMR in the children of group 1 - 51.5 ms, of group 2 - 28.4 ms, verifies a decrease of the rate of the neurodynamic processes of the NS in the children with heretotropia. In the study with the MOR technique, the time of response in the first group was - -31 (-127; 50) ms, in the second group - 22 (-29; 94) ms (р = 0.000008), a positive value of the indicator of the response time in the children of the second group is a consequence of the prevalence of inhibition processes in the central nervous system in most the examined patients. Conclusion . The obtained results show that the presence of heterotropia in the children of the second group reliably leads to decreased mobility of nervous processes and predominance of inhibition processes in the central nervous system. The combination of the low velocity of the response and expressed inertness of nervous processes in the children of the second group are indicative of a lack of coordination of the interrelations between the centers of the visual and motor analyzers.

One of the most common diseases of the cardiovascular system is cardiac arrhythmias. Assessment of the heart rate is one of the obligatory methods of pediatric examination and its deviation from the age norm may indicate a change in the child's health and be one of the first manifestations of the disease. Heart rhythm disturbances accompany various diseases, namely: congenital heart defects, cardiomyopathies, rheumatic and infectious diseases, intoxication, vegetative crises, endocrine diseases, diseases of the nervous system and others. Most often, in children's practice, it is not always possible to establish the cause of heart rhythm disturbances, as well as to classify the presence of organic or functional disorders without conducting morphological studies. Purpose — to study the features of heart rhythm and the state of the autonomic nervous system (ANS) among the children of primary school age with sinus bradycardia. Materials and methods. Children of primary school age with sinus bradycardia were examined (210 children). All children underwent: clinical examination, ECG at rest and after exercise, daily monitoring of ECG and heart rate, echocardiography, cardiointervalography with spectral analysis of heart rate. Results. Assessment of the cardiovascular system among children with bradycardia revealed the following features: 80.0% of children had no complaints, 68.0% of children at the age of 6–7 years and 55.0% of children at the age of 8–10 years had moderate bradycardia, 32.0% of children at the age of 6–7 years and 45.0% of children at the age of 8–10 years had significant bradycardia. After the exercise test, 71.0% of children still had bradycardia, which is typical for children at the age of 9–10 years and 29.0% of children had an acceleration of heart rate above the age norm. Holter monitoring revealed the following cardiac arrhythmias: sinus rhythm driver migration, ectopic rhythm, sinoatrial block, 2 grade atrioventricular block, atrial extrasystole and ventricular extrasystole. Different duration of sinoatrial pauses was detected: in the range from 1300–1400 ms among the most children (78.0%) to 1700–1800 ms among 1.8% of children. Data from spectral analysis of sinus rhythm showed the predominance of parasympathetic nervous system tone among the 84.0% of children, asympathicotonic (40.5%) and normal (44.9%) autonomic reactivity. Conclusions. Examination of the children of the primary school age revealed sinus bradycardia and bradyarrhythmia among the 80.7% of children. Bradyarrhythmia is typical for children at the age of 6–7 years, bradycardia — for children at the age of 9–10 years. Spectral analysis of the ANS showed an imbalance in the regulation of sinus rhythm: the predominance of the parasympathetic link, regardless of the initial state of the ANS and the violation of adaptive mechanisms. According to Holter monitoring, the duration of pauses is longer than normal for the given age (more than 1300 ms) indicates sinus node dysfunction and requires closer monitoring due to the risk of developing sinus node weakness syndrome and other threatening conditions in later life. The research was carried out in accordance with the principles of the Helsinki declaration. The study protocol was approved by the Local ethics committee of all participating institution. The informed consent of the patient was obtained for conducting the studies. No conflict of interest was declared by the authors. Key words: children, bradycardia, bradyarrhythmia, vegetative homeostasis.

The present study examined age differences in time-based prospective memory (TBPM) in primary school age children and tested the role of self-initiated memory retrieval and strategic time monitoring (TM) as possible developmental mechanisms. Fifty-four children were recruited from local primary schools (27 younger children, mean age = 7.2 ± 0.55 years, and 27 older children, mean age = 9.61 ± 0.71 years). The task was a driving game scenario in which children had to drive a vehicle (ongoing task) and to remember to refuel before the vehicle runs out of gas (TBPM task, i.e., the fuel gauge served as child-appropriate time equivalent). Fuel gauge was either displayed permanently (low level of self-initiation) or could only be viewed on demand by hitting a button (high level of self-initiation). The results revealed age-dependent TBPM differences with better performance in older children. In contrast, level of self-initiated memory retrieval did not affect TBPM performance. However, strategies of TM influenced TBPM, as more frequent time checking was related to better performance. Patterns of time checking frequency differed according to children’s age and course of the game, suggesting difficulties in maintaining initial strategic TM in younger children. Taken together, the study revealed ongoing development of TBPM across primary school age. Observed age differences seemed to be associated with the ability to maintain strategic monitoring.

Цель. Анализ влияния характера зрения (ХЗ)на показатели сложной сенсомоторной реакции на движущийся объект (РДО)у детей младшего школьного возраста с содружественным сходящимся косоглазием (ССК). Материал и методы. Было обследовано 33 ребенка (66 глаз), в возрасте 6–11 лет, с ССК на фонеHm4,6±2,5Д. Сформированы 3 группы, в зависимости от ХЗ, на фоне полной коррекции. 1 группа – 12 детей (24 глаза) с монокулярным ХЗ, угол косоглазия 5,9±4,0°, 2 группа –12 детей (24 глаза)с одновременным ХЗ, угол косоглазия 3,9±3,6°,3 группа – дети с бинокулярным ХЗ – 9 пациентов(18 глаз), угол косоглазия 0,9±0,8°. Всем пациентам проводилось стандартное страбологическое обследование. РДО была исследована с помощью аппаратно-программного комплекса «НС-Психотест»(ООО «Нейрософт). Результаты. Среднее время РДО в 1 группе –29,1±9,5мс, во 2 группе – 16,6±8,4мс, в 3 группе –-12,4±4,1мс (р <0,05). Положительное значение среднегруппового показателя РДО детей 1 и 2 группы является следствием преобладания у большинства обследуемых процессов торможения в ЦНС. Отрицательное значение среднегруппового показателя детей 3 группы является свидетельством преобладающей реакции НС в виде дисбаланса течения нервных процессов в сторону возбуждения в ответ на предложенную нагрузку. Выводы. Отсутствие у детей 1 и 2 группы бинокулярного зрения приводит не только к нарушению аккомодационно-конвергентных взаимосвязей в зрительном анализаторе, но и является причиной изменения зрительной экстраполяции, что приводит к снижению подвижности нервных процессов и преобладанию тормозных процессов в ЦНС(положительное значение средне группового показателя времени РДО детей 1 группы – 29,1±9,5 мс,2 группы – 16,6±8,4 мс).
