在三组不同难度心算作业时,采用遥测仪对31名健康受试者进行了EEG 检查。并通过计算机进行了功率谱分析。结果表明:1、随着计算难度增加,受试者β_2波能量值、心算错误率和对心算难度的主观评价值亦随之增大。各指标三组之间比较,均有显著性差异(PFS<0.01)。2、β_2波能量比值与主观评价值之间相关分析,二者呈正相关(P<0.01)。说明β_2波能量值变化与心算作业难度之间有一致性关系。
At three different levels of mental arithmetic, 31 healthy subjects underwent EEG by telemetry. Power spectrum analysis was done by computer. The results show that: 1, with the increase of computational difficulty, the β 2 wave energy, the error rate of mental arithmetic and the subjective evaluation value of difficulty of calculating mental arithmetic also increase. Each index between the three groups were significantly different (PFS <0.01). 2, β_2 wave energy ratio and subjective assessment of the correlation between the value of the two was positively correlated (P <0.01). This shows that there is a consistent relationship between the change of β_2 wave energy and the difficulty of mental arithmetic.
