FEATURES OF CHANGES IN INDICATORS OF THE FUNCTIONAL STATE OF THE CENTRAL NERVOUS SYSTEM IN RESPONSE TO THE CONDITIONS OF THE VIRTUAL ENVIRONMENT DEPENDING ON THE NATURE OF NEURODYNAMIC PROCESSES

The article examines the dynamics of indicators of the functional state of the central nervous system (CNS) in response to the features of the virtual environment in which cognitive-motor activity is implemented. 50 healthy volunteers took part in the study. Through psychophysiological screening measures and centile analysis, for the further implementation of the experiment, two groups of studies were obtained: «pronounced mobility of nervous processes» VPNP (n = 14) and «pronounced inertia of nervous processes» VINP (n = 13). The evaluation of the experimental activity was performed by means of the method of recording sensorimotor responses: simple visual-motor response and moving object response were used. The instrumental heart rate (HR) estimation method was also applied. Statistical processing was carried out using the Wilcoxon and Mann – Whitney criteria; indicators that reached the p < 0.05 value were considered statistically significant. As part of the evaluation of the experimental activity, statistically significant results were obtained (p < 0.05) indicating a deterioration in the functional state of the CNS in response to the conditions of the virtual environment (in which the exercise test was implemented) in the volunteers of the VPNP group. The results of the present study indicate the need to model the conditions of the virtual environment in which cognitive-motor activity is realized, depending on the features of the neurodynamic organization of sensorimotor reactions.
