Аннотация: The aim of this study is to identify the features of adaptive responses of the nervous system in students and the relationship between the success of arbitrary control of the heart rate and the dynamics of adaptive reactions in a competitive stress model.?METHODS: The research involved 82 students of the pedagogical University. To assess the regulatory and adaptive mechanisms of the central nervous system, we recorded the value and sign of the DC-potential in the frontal areas, and the magnitude of interhemispheric asymmetry in normal conditions and under the psycho-emotional load (the heart rate biofeedback game).?RESULTS: The two groups of students was allocated: the first group with a high degree of voluntary self-regulation and adaptation under the conditions of competitive stress included 33 people (40.3 %), and the second group with lower levels of self-regulation, which consisted of 49 people (59.7 %). In the “Successful” group, we noted the dominance of the left hemisphere, a high or medium level of activation of the frontal lobes, and hemispheric asymmetry within 3 mV. The most significant difference in the DC-potential level of the left hemisphere was in normal conditions (P=0.04). When exposed to emotional stress activation level of the frontal cortex increased. The “Unsuccessful” group is characterized by the dominance of the right hemisphere, the predominance of asymmetric and low levels of activation, a decrease in the average level of DC-potential of both hemispheres under stress, and less pronounced interhemispheric asymmetry. Also the interrelation between the activation level of the right hemisphere and heart rate (r = 0.37) was found.?CONCLUSIONS: Students with initially higher levels of activation effects in cerebral cortex successfully cope with the control of emotions in terms of competitive load and have greater adaptive capacity than those with low activation level, right skewed or less pronounced asymmetry of the activation processes.
