本文用信息流的方法分析了11名正常人和11名精神分裂症偏执型病人的脑电图,观察比较其α活动的传播方向。结果是:正常组两侧半球的α活动信息流均是从头的前部流向后部;而病人组两侧半球的α活动方向不同,右侧从前向后流动,左侧从头后部流向前部。t检验的结果表明两组被试者左侧半球α活动有非常显著的差异。 In this paper, 11 normal subjects and eleven paranoid schizophrenic patients were analyzed by flow of information, and their electroencephalogram was observed and compared. The results are: the normal hemisphere on both sides of the a-activity information flow from head to the front of the flow to the rear; and patients on both sides of the hemisphere α activity in different directions, the right front-to-back flow from the back of the left flow to the front . The t-test showed that there was a very significant difference in alpha activity in the left hemisphere between the two groups.
