EEG indicators of the central nervous system in individuals with different levels of psychophysiological adaptation

The purpose of the study is to assess functional activity of the brain, individual structural and functional formations of the central nervous system at different levels of psychophysiological adaptation (PFA) and to identify their contribution to the formation of low PFA level. Material and Methods. Using psychological and visual-motor tests, methods of heart rate variability, functional state of structural and functional formations of the central nervous system: "cortex", "cortical-subcortical interaction", "central regulation of the cardiovascular system" was evaluated; the integral PFA level was determined using the evaluation results. EEG was used to evaluate brain functional activity and the listed CNS formations. Results. As the level of PFA in the EEG decreased, indicators regarded as the anomalous ones increased: type IV EEG; unstable EEG dynamics; high index of (31 activity; flashes of bilateral synchronous waves. The maximum number of abnormal EEG parameters was revealed at low FS of structural and functional formation "central regulation of the cardiovascular system" in persons with low PFA level. Conclusion. Identification of the maximum number of abnormal EEG indicators at low FS of structural and functional formation of the central nervous system "central regulation of the cardiovascular system" in persons with low PFA level testified to its main contribution to the formation of a low integral level of PFA.
