Electroencephalograms were recorded in 76 normal children between 10-12 years of age and several parameters were calculated from the results of spectral analysis. Sections of recordings which were free of artefacts, taken under different conditions (eyes open, eyes closed and during tests of mental arithmetic and vocabulary with the eyes closed were analysed. In these normal children, there was significant asymmetry of the alpha 1, beta 1, theta rhythms, and related parameters at rest, but the asymmetry was not necessarily found to correlate with the laterality of hand, eye, foot or all three. Vocabulary, and to a greater extent arithmetic significantly decreased alpha rhythms. Arithmetic affected both hemispheres equally but vocabulary depressed the alpha rhythms more obviously on the left.
对76名10至12岁的正常儿童进行了脑电图记录，并根据频谱分析结果计算了几个参数。分析了在不同条件下（睁眼、闭眼以及闭眼进行心算和词汇测试时）无伪迹的记录片段。在这些正常儿童中，静息时α1、β1、θ节律及相关参数存在显著不对称，但这种不对称不一定与手、眼、脚的偏侧性或三者全部相关。词汇，以及在更大程度上心算显著降低了α节律。心算对两个半球的影响相同，但词汇对左侧α节律的抑制更明显。
