目的采用静息脑电技术研究正常成年人额叶alpha波偏侧化是否受到年龄因素的影响,同时进一步验证静息脑电alpha波偏侧化作为情绪调节能力指标的稳定性。方法正常青年人(18~25岁)30人,正常中年人(40~50岁)30人,首先采集脑电,对脑电数据进行离线分析,将最终数据转化成自然对数,然后用SPSS 17.0软件处理,对两组人群进行分析。结果正常成年人额叶静息脑电Alpha波存在偏侧化(F=6.865,P<0.05)。青年组与中年组额叶静息脑电在F3/F4点(t=-0.346,P>0.05);F7/F8点(t=-0.121,P>0.05);FP1/FP2点的偏侧化程度均不存在差异(t=-0.192,P>0.05)。结论正常成年人额叶静息脑电偏侧化不受年龄因素影响,额叶静息脑电Alpha波偏侧化作为情绪调节能力的指标在年龄差异上具有一定的稳定性。
Objective To study if the lateralization of alpha-wave in frontal lobe of normal adults is affected by age factors by resting electroencephalography (EEG), and to further verify the stability of alpha-wave of resting electroencephalogram (EEG) as the index of emotion regulation. Methods Normal young people (18-25 years old) 30 people, normal middle-aged people (40-50 years old) 30 people, the first collection of EEG, EEG data off-line analysis, the final data into natural logarithm, and then use SPSS 17.0 software processing, analysis of two groups of people. Results Normal adult frontal lobe resting electroencephalogram Alpha wave had lateralization (F = 6.865, P <0.05). The resting electroencephalogram in the frontal lobe of middle-aged and middle-aged patients at F3 / F4 (t = -0.346, P> 0.05), F7 / F8 (t = -0.121, P> 0.05) There was no difference between the two groups (t = -0.192, P> 0.05). Conclusion Normal adult frontal lobe resting EEG is not affected by age. Frontal lobe resting electroencephalogram Alpha wave lateralization has some stability as an indicator of emotion regulation ability in age.
