研究了正常人在安静和思维状态下阵发性 4 0Hz脑电事件相关信号 (40HzERP)的特征变化 ,探讨阵发性 4 0HzERP与年龄、性别、文化程度和智力测验得分之间的关系 ,同时对 4 0HzERP不同参数进行比较。结果表明 :正常人在安静状态下阵发性 4 0HzERP出现的时间、面积和峰值均明显低于思维状态下的测试 ,而定向力及计算力测试时阵发性 4 0HzERP低于视空间测试。思维活动时阵发性 4 0HzERP增加幅度与简易精神状态量表 (MMSE)和韦氏成人智力量表 (WAIS)得分呈正相关。
The characteristics of paroxysmal 40Hz ERS (40HzERP) in normal and silent state were studied, and the relationship between paroxysmal 40HzERP and age, gender, educational level and intelligence test scores was studied. At the same time, Compare different parameters of 40HzERP. The results showed that the time, area and peak value of paroxysmal 40 Hz ERP in normal subjects were significantly lower than those in the state of mind under normal conditions. However, the paroxysmal 40 Hz ERP was lower than that in the visual acuity test. The rate of increase in paroxysmal 40 HzERP at thought activity was positively correlated with MMSE and WAIS scores.
