SEX DIFFERENCES OF CORTICAL INTERACTIONS IN CONNECTION WITH THE ACCURACY OF SHORT TIME INTERVALS RECOGNITION AND INDIVIDUAL PSYCHOLOGICAL CHARACTERISTICS

Abstract

Sex differences in brain electrical activity both at rest and after recognition of visual stimulus exposure period were revealed in the research. The features of cortical activation, functional asymmetry and spatio-temporal synchronization of electrical activity of the brain regions in young men and women in relation to short time intervals perception are analyzedin the paper. The analysis of sex differences in correlation links between psychological indicators (constitutional, intellectual, psychodynamic and adaptation) was carried out. The characteristics of the functional activity of brain in groups of young men and women with different accuracy and speed time intervals recognition, accuracy of intellectual tasks solution and level of social-psychological adaptation were described. On the basis of sexual peculiarities of brain mechanisms the authors suggest some assumptions about the psychological characteristics of adaptation and regulation of intellectual activity in young men and women.
