Age-dependent changes in EEG activity were assessed in a comparison of EEG recordings taken from 102 children at the ages of 6 and 10 years. Of the 2-to-13-cycle-a-second activity recorded from the left occipital region, the fast alpha frequencies (10 to 13 cycles a second) showed a significant increase at the expense of all slower frequencies. The children were divided into two groups according to whether they had been exposed to a small or large number of biological risks; in the latter group the extent of the increase in fast alpha activity was negatively related to the number of additional psychosocial risks. This effect was even more pronounced in the group of brain-damaged children, where the smallest age-dependent shift in the EEG frequencies was seen in the group with both minimal brain damage and a high psychosocial risk factor. These data suggest that the exposure of children with minimal brain damage to multiple psychosocial risks may lead to a delay in the maturation of the brain that can be detected by neurophysiological methods.
通过比较102名6岁和10岁儿童的脑电图记录，评估了脑电图活动的年龄依赖性变化。在从左枕叶区域记录的每秒2至13次循环的活动中，快速阿尔法频率（每秒10至13次循环）显著增加，而所有较慢频率的活动则相应减少。根据儿童所面临的生物风险数量的多少，将他们分为两组；在生物风险数量较多的那组儿童中，快速阿尔法活动的增加程度与额外心理社会风险的数量呈负相关。这种效应在脑损伤儿童组中更为明显，在脑损伤最小且心理社会风险因素较高的组中，脑电图频率随年龄的变化最小。这些数据表明，轻度脑损伤儿童暴露于多种心理社会风险中，可能会导致大脑成熟延迟，这种延迟可以通过神经生理学方法检测到。
