应用脑电功率谱分析意境作业心理调控的特异性
目的通过检测接受和未接受意境作业训练的受试者脑电功率,分析意境作业心理调控的脑电特异性。方法选择在校大学生为受试对象,采用随机对照的方法,分为实验组和对照组,比例为1:1,对实验组受试者进行意境作业培训,对照组不做任何干预,意境作业内容不告知。应用脑电同步检测意境作业过程中的脑电变化,并从总体、时段、空间3方面对δ、θ、α、β4个频带比较分析;时段分为4个静息态(0~3)和3个意境作业(1~3)7个时段,不同静息态时段间为意境作业时段;通过对两组α、β频带各导联绝对功率的比较,探寻空间的差异。结果总体比较,意境作业和静息态,两组在δ、θ、α、β频带均表现出极显著性差异(P〈0.001),实验组...

Summary: | 目的通过检测接受和未接受意境作业训练的受试者脑电功率,分析意境作业心理调控的脑电特异性。方法选择在校大学生为受试对象,采用随机对照的方法,分为实验组和对照组,比例为1:1,对实验组受试者进行意境作业培训,对照组不做任何干预,意境作业内容不告知。应用脑电同步检测意境作业过程中的脑电变化,并从总体、时段、空间3方面对δ、θ、α、β4个频带比较分析;时段分为4个静息态(0~3)和3个意境作业(1~3)7个时段,不同静息态时段间为意境作业时段;通过对两组α、β频带各导联绝对功率的比较,探寻空间的差异。结果总体比较,意境作业和静息态,两组在δ、θ、α、β频带均表现出极显著性差异(P〈0.001),实验组8频带绝对功率值低于对照组,θ、α、β频带绝对功率值均高于对照组。时段比较,两组6频带在静息态0、3时段和意境作业1、2时段表现出显著差异(P〈0.05),0频带在静息态1、2时段和意境作业3时段表现出显著差异(P〈0.01);实验组δ、θ频带功率变化类似余弦曲线,α、β频带各时段均有显著性差异,仪频带从意境作业1时段开始波幅较平稳,β频带自意境作业2时段开始波幅较平稳。空间比较,两组δ、θ频带各导联差异不显著(P〉0.05),α频带在F7、C3、C4、P3、P4、13、T4、T5、T6、PZ、O1、O2导联均表现出显著性差异(P〈0.05),β频带在FP2、F7、F8、P3、P4、T5、T6、C4、PZ、O1、O2表现出显著差异(P〈0.05),α、β频带最高功率均集中在O1、O2导联。结论意境作业能够诱发δ、θ、α、β频带的节律性反应,尤其在α、β频带的时段上表现出平稳的规律,在空间上表现出快、慢波交替变化的规律,说明意境作业能够有效提高脑的安静程度,改善大脑的紧张状态,进而调整不良情绪。 |

Bibliography: | Objective To analysis the electroencephalographical (EEG) specificity of psychological adjustment of Imaginary Working (IW) by comparing the EEG power of trained subjects and untrained subjects. Methods University students were recruited as the subjects, randomly and equally divided into experimental group and control group. The students of experimental group were trained Imaginary Working, with no intervention on those of control group. The changes of powers during the process of Imaginary Working were synchronously detected by EEG, furthermore, the delta (δ) band, theta (θ) band, alpha(α) band, and beta (β)band were compared and analyzed from three aspects of general points, time interval, and different leads. Results There were very significant differences in δ、θ、α、 and β bands between the two groups at both Imaginary Working (IW) and resting state (RS) (P 〈 0. 001 ) : the absolute power of δ band in experimental group was lower than that of control group, and the absolute powers of 0, θ,αand β bands were |
