TRANSFORMATION OF PSYCHO-PHYSIOLOGICAL PROPERTIES IN WAR SITUATIONS

Background
Neurodynamic and neurophysiological properties were studied in 53 men aged 21-35 years at the beginning and after 6 months of martial law.

Material and methods
The neurodynamic, individual-typological and sensorimotor properties of the subjects were studied while processing information using the “Diagnost 1M” system. The neurophysiological characteristics of long-latency visual evoked potentials (LVEPs) were determined using the “Neurokom” EEG-complex.

Results
At the beginning of the martial law, men were divided into two subgroups: conditionally resistant (the first subgroup) and not resistant (the second subgroup) to long-term psycho-emotional stress. It was found that neurodynamic, individual-typological properties of the first subgroup changed little and differed significantly from the second subgroup: balance (BNP), functional mobility (FMNP) and strength of nervous processes (SNP). Individual-typological properties of the nervous system (FMNP, SNP, BNP) and sensorimotor properties (SVMR, RC1-3, RC2-3) underwent significant changes in the representatives of the second subgroup in 6 months. Subjects of this subgroup had lower amplitude values between the peak intervals of N1-P2, P2-N2 and Р3 peak, as well as significantly shorter latency of Р1, Р2 and longer Р3 components, which indicates a violation of cortical-subcortical interaction.

Conclusions
It was found that the studied properties determine the formation of adaptive reactions in the conditions of martial law.
