Abstrakt: The paper presents data on the populational laterality proportions among men and women. Analysis of cardiac rhythm variations in right- and left-handed men and women in rest and during mental loading has shown a more pronounced sympathetic domination in left-handed examinees unlike right-handers. The most significant differences in the autonomic balance during mental loading were revealed between the left-handed and right-handed men. An earlier physiological maturation was established to be more characteristic of left-handed women as compared with right-handers. On the background of low and high levels of estrogens a correlation was revealed between the level of hormones and parameters of autonomic balance of the autonomic nervous system both in right-handed and left-handed women.
