Study of Neurophysiological and Hemodynamic Indicators in Persons With High and Low Levels of Executive Control

This work is devoted to the study of the individual characteristics of cerebral circulation, galvanic skin response and heart rate during mental, sensorimotor and sensory activity. In two groups, differing in the level of behavior control (precise and imprecise), a comparative analysis of behavioral and physiological indicators was carried out. Imprecise subjects before the test (readiness state) GO/NOGO showed higher indices of the tone of the arterioles and venules of the cerebral vessels in the basin of the carotid arteries. During the GO/NOGO trial, a more reactive increase in vascular tone was observed in the precise group, more pronounced in the right hemisphere. In the imprecise group, a higher level of mental stress was registered in terms of GSR and heart rate during mental counting. GSR was also more pronounced in this group when viewing images. The optimal and non-optimal types of information load portability are discussed.
