Samples of students aged 18-20 years, 50 males and 50 females, were examined by a vast program, including standard anthropometry, psychological testing, EEG registration, HRV registration as a separate cut during EEG recording. To estimate intersystem covariability Spearman rank correlation and factor analysis were enlisted. Results and discussion. Frequencies of intersystem correlations are much more numerous for females as compared to males. The greatest number of significant correlations for girls fall on associations of spectral HRV parameters (HF, LF, LF/HF) and power EEG parameters in different bands and cuts. The picture for males embraces HRV parameters (VLF, IC) and EEG parameters in frequency ranks lower than 9-11 Hz in occipital and temporal cuts. Seldom correlations of HRV parameters for both sexes with soma and psychometrics are fixed. Conclusion. The results allow to discuss different by sex «adaptive endophenotypes», being the background of the behavior patterns. In particular, associations of EEG parameters with HRV parameters, connected with the functioning of higher parts of the brain for males; with HRV parameters, reflecting sympathetic and parasympathetic influences balance – for females. Females are characterized by more pronounced correlations of physiological parameters with soma, especially transversal development of soma (shoulder width, chest transversal diameter among others). |
