基于脑电波α频带相对功率分析意境作业对抑郁状态大学生的解郁效应

Resolving depression effects of artistic work on depressed college students: a analysis based on EEG α-band relative power

目的通过检测接受和未接受意境作业训练的抑郁状态大学生脑电波α频带相对功率,分析意境作业对抑郁状态大学生的解郁效应。方法将24名抑郁状态大学生按照1∶1原则分为两组,对实验组进行意境作业培训,对照组不做任何干预。实验前和实验组培训后分别采集提取两组脑电波α频带相对功率,采集过程依次分为静息态0、意境作业1、静息态1、意境作业2、静息态2、意境作业3、静息态3共7个时段。结果两组导联FZ、F8、FT7、FCZ、FT8、C3、CZ、CPZ、TP8、P4、T5、P3、PZ、T6、O1在静息态0差异有统计学意义(P <0. 05)。意境作业1中,两组导联FZ、FT7、FCZ、FT8、CZ、TP7、T5、PZ、CPZ、TP8、P3、P4、T6、O1差异有统计学意义(P <0. 05);意境作业2中,导联FP2、FC3、FT8、FT7、FCZ、FC4、TP7、P4、T6、T3、CP3、TP8、P3、O2差异有统计学意义(P <0. 05);意境作业3中,导联FP2、FT7、FCZ、FT8、F3、CZ、O1、TP7、TP8、P3差异有统计学意义(P <0. 05),在意境作业操作整个过程中,两组在导联FCZ、FT8、TP7、TP8、P3差异有统计学意义(P <0. 05)。结论意境作业能够诱发脑电波α频带的节律性反应,表现为后脑区和顶区α频带高相对功率,对抑郁状态具有一定缓解作用。

Objective To analyze the resolving depression effects of artistic work on depressed college students through detecting changes of EEG α-band relative power in depressed college students received or not received artistic work training. Methods The depressed college students（ n = 24） were divided,according to 1∶1 principle,into test group and control group,and the test group was given artistic work training and control group was not given any interventions. The changes of EEG α-band relative power were collected,compared and analyzed from 2 groups before the experiment and after the training. The collective period was divided into 7 phases： resting state 0,artistic work 1,resting state 1,artistic work 2,resting state2,artistic wark 3,resting state 3. Results The leads of FZ,F8,FT7,FCZ,FT8,C3,CZ,CPZ,TP8,P4,T5,P3,PZ,T6 and O1 showed significant difference between 2 groups at resting state 0（ P 〈0. 05）. The leads of FZ,FT7,FCZ,FT8,CZ,TP7,T5,PZ,CPZ,TP8,P3,P4,T6 and O1 showed significant difference between 2 groups in artistic work 1（ P 〈0. 05）. The leads of FP2,FC3,FT8,FT7,FCZ,FC4,TP7,P4,T6,T3,CP3,TP8,P3 and O2 showed significant difference between 2 groups in artistic work 2（ P 〈0. 05）. The leads of FP2,FT7,FCZ,FT8,F3,CZ,O1,TP7,TP8 and P3 showed significant difference between 2 groups in artistic work 3（ P 〈0. 05）. The leads of FCZ,FT8,TP7,TP8 and P3 showed significant difference between 2 groups in the whole operation of artistic work（ P 〈0. 05）.Conclusion Artistic work can induce sexual responses of EEG α-band,shows a higher α-band relative power in metencephalon and parietal regions,and has some relieving effect on depression status.
