Palabiyik A. Intersystem interaction of neurophysiological and autonomic nervous system under the condition of information processing of different complexity and modality

The existence of a dome-like interaction of the neurophysiological and autonomic nervous system from the speed of presentation, modality of signals and complexity of the task is proved. Differentiation of verbal signals at speeds of 30 and 60 per minute, and figurative 90 stimuli was characterized by a gradual increase in cognitive and neurophysiological mechanisms of regulation of the autonomic nervous system, coordinated interaction of autonomic and central, sympathetic and parasympathetic units, strengthening integrative processes. This was confirmed in HRV and SARS, which were characterized by high values of SI, TR, IC, LF/HF and the speed of motor reactions and a small number of errors. It is shown that a further increase in the rate of differentiation of image signals to 120 and verbal to 90 per minute leads to a decrease in the success of information processing (a significant number of errors) and multidirectional changes in the interaction of neurophysiological and autonomic nervous systems. This indicated the transition of the functional system from the optimal state of autonomous regulation to the imbalance between the central and autonomous control circuit of the SR and the development of deregulation and vegetative-cognitive interference, as well as cognitive dissonance. This is confirmed by the pronounced dominance of the central mechanisms of regulation of the autonomic nervous system, high values of the stress index (SI) and disturbance of the sympathetic-vagal balance (LF/HF) in regulatory processes.
