SEX DIFFERENCES OF THE HUMAN BRAIN HEMODYNAMIC SUPPLY DURING THE PERFORMANCE OF THE SIMULATED COGNITIVE ACTIVITY
The article provides research data devoted to the study of an actual scientific problem of human physiology - the identification of sex differences in human cerebral hemodynamics during the solving cognitive tasks. Cognitive activity was modeled using a two-colored Schulte – Gorbov test, cerebral hemodynamics was assessed by the method of rheoencephalography, registering it in the fronto-mastoidal and occipito-mastoidal leads on the left and right. The obtained data indicate that the hemodynamic supply of brain activity in subjects of different sexes during the solution of cognitive tasks differs significantly. In particular, it was found that when the Schulte – Gorbov test was performed in male subjects, hemodynamic changes were observed in the occipital region mainly on the right, while in females – in the occipital region both: on the left and on the right.
