摘　　要：目的通过测量不同思维主题下意境作业α频带的脑电功率值,分析其对各脑功能区的特异性效应。方法将48名大学生分为2组,对实验组进行3种意境作业培训,对照组不做任何干预。采集2组意境作业α频带脑电功率进行比较分析。结果实验组在作业态和静息态中,枕叶、顶叶的功率均高于对照组(P<0.05)。不同的意境作业引发不同的脑电功率变化,思维主题"我在玫瑰花丛中漫步"下的意境作业时,左右脑对侧导联在FP1-FP2、F7-F8、C3-C4、P3-P4、T5-T6、O1-O2均有显著性差异(P<0.05),且右侧导联功率均大于左侧导联,作业结束后的静息态枕区功率降低。思维主题"春天的阳光温暖着我的身体""我的每一个毛孔都在自由地呼吸"下的意境作业,仅F7-F8、P3-P4对侧导联有显著性差异(P<0.05),作业结束后的静息态枕区功率升高,在最后一次静息态功率升至最高。结论意境作业的静心安神效应体现在顶叶、枕叶的α频带高功率表现;通过练习意境作业,可以使大脑更容易进入和保持安静状态。不同意境作业引发的各种感觉效应可能与对应的各个脑功能区反应相关。Objective To analyze the effects of different kinds of Image Thinking on brain functional area by measuring alpha band electroencephalograph （EEG） power. Methods 48 college students were enrolled and divided into two groups. Subjects in the experiment group received three kinds of Image Thinking intervention, while those in the control group did not receive any intervention. Alpha band ab- solute power of two groups was measured to compare and analyze. Results The alpha band absolute power value of the experiment group was higher than that in the control group at occipital lobe, parietal lobe, and temporal lobe in both active and resting state （ P 〈 0.05 ）. The power in c~ frequency range was significantly different in three kinds of Image Thinking status. When imagining ＂I am rambling in the rose bushes＂, there was statistically significant difference in contralateral lead in （FP1-FP2）, （F7-F8）, （ C3-C4）, （P3-P4）, （TS-T6）, and （O1-O2） （P 〈 0.05 ）. Moreover, power in the right hemisphere was higher than left hemisphere, and after active stage the power of occipital lobe reduced. When imagi- ning ＂the spring sunshine is warm on my body My every pore is breathing freely＂, there was statistically significant difference in contralateral lead in （ F7-F8 ） and （P3-P4） （ P 〈 0.05 ）. The alpha band abso- lute power increased at occipital lobe after active stage, then the power increased to peak at final resting state. Conclusion Image thinking exhibits a significant tranquilizing effect according to the reflection of the high power of alpha band at occipital lobe and parietal lobe. Different kinds of feeling effect caused by Image Thinking maybe related to the function of every brain area.
