Kozhemyako T. Neurophysiological and vegetative mechanisms of information processing of teenagers with different individually-typological characteristics of the nervous system

The connections of the individually-typological characteristics of the central nervous system, the EEG- brain activity and the regulatory reactions of the cardiovascular system on the experimental load of the information processing are established in the dissertation. The scientific novelty of the results: the first time development of the theory of the connection of individually-typological characteristics of the higher areas of the central nervous system with functional peculiarities of the neurophysiological and autonomous mechanisms of regulation of the heart rate (HR) during the psychomotor activity. For the first time, high dependence of changes in the power of the main EEG rhythms and the spectral characteristics of the autonomous regulation of the HR during the information processing on the neurodynamicindividually-typological characteristics of the higher areas of the central nervous system was revealed. It was also revealed that during the information processing, the power of the main EEG rhythms, the coefficient of brain activation and the autonomous mechanisms of regulation of the heart rate are dependent on the FMNP. The proof of this is that the individuals with high characteristics of the FMNP did a test task on the information processing with fewer errors, higher power of the main EEG rhythms and the level of brain activation and the spectral characteristics of autonomic regulation of the heart rate than those surveyed with a low level of studied typological characteristics. The obtained data are important for perspective fundamental and applied researches of psychophysiological mechanisms of providing psychomotor activity. The results are practical because they broaden the theoretical concepts and substantiate the role of neurodynamicindividually-typological characteristics of the higher areas of the central nervous system in encreasing the functioning of the brain processes and autonomous regulation of the heart. From a practical point of view, the work shows the role of individually-typological characteristics of the higher areas of the central nervous system in encreasing the functioning of the brain and heart processes, and it substantiates the individual approach in the implementation of technologies for psychomotor activity management.
