The present study aimed at clarifying the characteristics of variability of the resting arousal EEGs in normal and mentally retarded children. Their ages ranged from 3 to 15 years in 58 normal and from 7 to 18 in 63 retarded. The EEG was recorded monopolarly from six regions of the scalp. The data analysed by a multipurpose digital computer comprised auto-power spectra and a coefficient of variation of power at each frequency. The variability of power at peak within the theta frequency band in both groups of children showed a notably higher value as compared with other frequency bands in all regions. We discussed some of the problems of treating this variability of power as a general characteristic of theta waves or as a developmental one.
本研究旨在阐明正常儿童和智力发育迟缓儿童静息觉醒脑电图的变异性特征。58名正常儿童年龄在3至15岁之间，63名智力发育迟缓儿童年龄在7至18岁之间。脑电图通过单极记录法从头皮的六个区域进行记录。由多功能数字计算机分析的数据包括自功率谱和每个频率的功率变异系数。两组儿童在θ频段内峰值处的功率变异性在所有区域均显示出与其他频段相比明显更高的值。我们讨论了将这种功率变异性视为θ波的一般特征或发育特征所涉及的一些问题。
