应用脑电功率谱分析意境作业心理调控的特异性
Specificity analysis of psychological adjustment of Imaginary Working based on electroencephalographical power spectra
摘要
Abstract
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,αand βbands between the two groups at both Imaginary Working (IW)and resting state (RS)(P <0.001):the absolute power of δband in experimental group was lower than that of control group,and the absolute powers of θ,αand βbands were higher than those of the control group.There were significant differences of absolute power of δband at RS0 ,IW1 ,IW2 and RS3 (P <0.05),and there were significant differences of θband at RS 1 ,RS2 and IW3 (P <0.01 ).The changes of absolute power of δand θbands in experimental group were close to cosine curves.Although there were statistical differences of αband and βband at each state,from IW1 period the amplitude of αband began to keep stable,and from IW2 period the amplitude of βband did.There were no significant differences of δband and θband appeared different leads between the two group(P >0.05).The absolute power of αband showed statis-tical differences in lead of F7,C3,C4,P3,P4,T3,T4,T5,T6,PZ,O1 and O2(P <0.05),while that of βband showed significant difference in lead of FP2,F7,F8,P3,P4,T5,T6,C4,PZ,O1 and O2 (P <0.05).The highest power of αand βband both appeared in the lead of O1 and O2.Conclusion Imag-inary Working induced the rhythmic response of δ,θ,αand βband,especially the rhythm alternated fast waves and slow waves.It is suggested that Imaginary Working keep the brain in rest state,and relieve tension,and adjust negative emotions.关键词
