Gender difference in emotion regulation:a resting EEG study / 中华行为医学与脑科学杂志

ABSTRACT

Objective Frontal resting EEG asymmetry was used to evaluate the gender effect of emotion regulation.Methods The resting EEG was recorded in 30 healthy volunteers (19-26 years old) by the guide 40 amplifier,and off-line analysis on EEG data were conducted by scan4.3 software.The statistical analysis were performed using SPSS 17.0.Results In normal human,frontal resting EEG alpha power was statistically significant(F=4.918,P =0.035).Asymmetry and gender interaction group (F =0.668,P =0.421),electrode point and gender interaction group (F =0.283,P =0.756),electrode point and asymmetry interaction group (F =1.418,P =0.260),electrode point,asymmetry and gender interaction group (F =1.164,P =0.327) had no statistical significance (P ＞ 0.05).The comparison of male and female asymmetry degree of each electrode point (F4/F3 group t =0.465,F8/F7 groupt=0.809,FP2/FP1 group t=1.542) had no statistical significance (P＞0.05).Conclusion Normal human brain hemispheres exist asymmetry.The asymmetry does not exists gender effect.In non-task state,frontal resting EEG alpha power asymmetry can not be recognized as the indicator of emotion regulation ability.
