摘要目的 采用额叶静息脑电偏侧化来研究情绪调节的性别效应.方法 应用40导放大器采集30名19～ 26岁正常人的静息脑电,通过scan4.3软件对脑电数据进行离线分析,最后用SPSS 17.0软件进行统计分析.结果 正常人脑左右半球间alpha波功率差异有统计学意义.偏侧化与性别交互效应组,极点与性别交互效应组,极点与偏侧化交互效应组,极点与偏侧化与性别交互效应组,均差异无统计学意义(F=0.668,1.418,1.164,P＞0.05).男女偏侧化程度F4/F3组(t=0.456,P=0.646),F8/F7组(t=0.809,P=0.425),FP2/FP1组(t=1.542,P=0.134),各极点均差异无统计学意义(P＞0.05).结论 正常人大脑左右半球存在偏侧化,偏侧化不存在性别差异,额叶静息脑电alpha波功率偏侧化,在非任务状态下不能作为情绪调节能力的指标.

abstractsObjective 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.
