During the information loading in children, the changes of coefficient of functional asymmetry, reflecting strengthening role of left hemisphere in realization of mental activity in the age of 7 to 8 years are revealed. At the same time, shifts of diagnostic parameters of variability of cardiac rhythm depending on age, sex and direction of changes in coefficient of asymmetry are found. Most pronounced changes were found in indexes of activity of sympathetic and parasympathetic nervous system, thus more noticeable change by sympathetic nervous system at loading was observed in girls of the first class, and parasympathetic — in boys of the second class. Dependence of changes of coefficient of functional asymmetry at loading of reference values is established in sympathetic nervous system and Bayevsky index at right-handed persons of 8 years.
