The purpose of research is to develop a biotechnical system (BTS) using neuroelectrostimulation of the peripheral nerve formations of the neck to assess and correct the psychophysiological l state of a person.Methods. The study involved 79 volunteers-subjects, divided by randomization into the main, control and placebo groups. The assessment of psychometric parameters of working memory was carried out using the dual 2-back test, and the assessment of the functional state was carried out using the analysis of heart rate variability (HRV). Correction of the psychophysiological state was carried out by stimulating the nerve formations of the neck with a spatially distributed field of voltage impulses; the target of stimulation was the cervical ganglia of the sympathetic nervous system.Results. The results of the study showed that the proposed structure of the BTS and the method for correcting the human psychophysiological state can improve working memory performance and normalize the state of the autonomic nervous system after five correction procedures. The results obtained on the test practically do not change and remain after 2 months.Conclusion. BTS, which includes a block of multichannel neuroelectrostimulation of peripheral nerve formations of the neck, is effective for correcting human psychophysiological l state, which is important for solving the problems of finding new ways and methods to improve human cognitive activity in the field of education.
