Cognitive tasks involved determining signal modality, visual shapes or word meaning, as well as quick error-free reactions with the left (gol) or right (gor) hand or motor inhibition (nogo). The rate of signal presentation increased gradually (30, 60, 90 and 120 per minute). The ANS was examined based on heart rate variability (HRV), scattergram area (S), periodic (SD2) and aperiodic (SD1) oscillations of correlation rhythmography (CR). Results. Differentiation of verbal and visual cues presented at a low rate was associated with increased activity of cognitive and neurophysiological mechanisms of ANS regulation, coordinated sympathoparasympathetic interaction, and enhanced integrative processes. High rate presentations led to divergent changes in cognitive function and ANS: increased HRV and decreased SD1 and SD2, increased number of errors, and decreased motor reaction time and S. Conclusions. Interactions between cognitive function and ANS were related to the rate of presentation and signal modality: increased interactions occurred with low rate presentations, whereas, high rate (visual) presentations impaired performance and also reduced autonomic-cognitive interactions.

Transformation of Psycho-Physiological Properties in War Situations

“…First, by interference of nervous processes [14,21], which are the basis of mental activity. Secondly, by the presence of dominant states [26], and thirdly, by the processes underlying the development of depression of psychophysiological properties, the driving force of which is the imbalance of cortical-subcortical interactions in the brain structures and impossibility of high-quality processing of information [18]. The validity of this assumption is confirmed by the results of a neurophysiological study of latency and amplitude characteristics of LVEP in abductions Р 3 , Р 4 , О 1 and О 2 .…”

“…The first of these mechanisms is determined by the individual typological properties of the nervous system of the subjects and is indicated by FMNP, SNP and BNP. It has been proven that these indicators are genetically determined [13,26] and they did not change during 6 months of war in the first group of subjects. The second of these mechanisms lies in the plane of analysis of the results obtained in the second subgroup.…”
