摘要

The work was performed on two groups of young men aged 18-22 years with and without sexual experience. Boys conducted a subjective olfactory assessment of body odors of girls located in different phases of the menstrual cycle, collected in an intact state, and while listening to rock music for an hour while recording multichannel EEG. The obtained data on a subjective assessment and change in spectral power in narrow frequency ranges in response to olfactory stimulation were subjected to multivariate analysis of variance. It was found that the olfactory attractiveness of receptive odor tests of girls for boys is higher and decreases under the influence of rock music mainly for odor samples collected in the non-receptive phase of the menstrual cycle of donors. The background electrical activity of the brain of young men who engage in regular sex life is characterized by a lower spectral power in all frequency ranges except beta rhythms. EEG reactions to intact odor stimuli in all young men are accompanied mainly by a decrease in spectral power in the theta1 rhythm and an increase in the delta and alpha2 frequency ranges. The detected EEG reaction is characteristic of non-receptive odor samples of girls. In young men with a lack of sexual life, the EEG reaction to intact odor tests is more generalized. When young men with regular sexual life are presented with the smells of girls collected while listening to rock music, the spectral power decreases in theta2 and alpha1 rhythms. Young men with a lack of sexual life react to the smells of girls collected while listening to rock music, with only a slight increase in the average spectral power in theta1 and alpha1 rhythms, and a decrease in the alpha1 frequency range. Apparently, the influence of rock music did not have a significant effect on girls who are in the receptive phase of the ovarian-menstrual cycle, and the lack of reliable EEG reactions in boys of both groups can be explained by the significant effect of the girls' individual smell on a particular boy.
