情绪调节的性别效应：额叶静息脑电偏侧化研究

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SPSS17．0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伊=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），FS／F7／组（t=0．809，P=0．425），FP2／FPl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。

Gender difference in emotion regulation：a resting EEG study

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 per- formed 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 gen- der 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 signifi- cance （P 〉 0.05 ）. The comparison of male and female asymmetry degree of each electrode point （F4/F3 group t = 0. 465 ,FS/F7 group t =0.809,FP2/FP1 groupt= 1.542） had no statistical significance （P〉0.05）. Conclusion Normal hu- man brain hemispheres exist asyrrmEtry. 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.
