基于α频带脑电功率时序特征分析意境作业的静心安神效应

Timing characteristics analysis of the tranquilizing effects of Imaginary Working based on the alpha band electroencephalogram power

目的通过脑电检测分析意境作业在α频带绝对功率的时序特征,探寻静心安神效应。方法以在校大学生为受试对象,按照1∶1的比例随机分成实验组和对照组。实验组接受意境作业干预,对照组不进行任何干预。在意境作业干预训练后,采集2组α频带绝对功率进行比较分析。结果 2组在各时段α频带脑电绝对功率均有统计学差异(P<0.05);实验组α频带的绝对功率值较对照组更高,综合比较各时点数据较对照组更平稳。结论意境作业训练能够诱发人脑α频带的节律性反应,随时间延续呈现平稳态势,并存在明显的后续干预效应,具有明显的静心安神作用效应。

Objective To explore the tranquilizing effects of Imaginary Working by investigating the timing characteristics of the alpha band electroencephalogram（ EEG） power. Methods College students as volunteer subjects were recruited and randomly divided into experimental group and control group at 1∶ 1 ratio. The experimental group received Imaginary Working intervention while the control group did not receive any intervention. After Imaginary Working intervention training,the alpha band absolute power of two groups was measured to compare and analyze. Results Alpha band EEG absolute power in the two groups were statistically different at all time periods（ P〈0. 05）. The absolute power value of the experimental group was higher than the control group,appeared more steady than the control group at each time point. Conclusion Imaginary Working can induce the alpha band rhythm response and maintain the effects with time as a subsequent effect. Imaginary Working presents with an apparent tranquilizing effect.
