Abstract: 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 absolute 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 α 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),( T5-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 imagining "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 absolute 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.
