对30名年龄在16-22岁的正常男性进行了32个通道的脑电记录。在整个年龄范围内，Delta的活动都有所下降。这种下降在左侧额区和颞区最大；没有枕部导联表现出这种模式。基于归一化地图的相对脑电幅度分析显示，阿尔法、德尔塔和西塔频段随着年龄的增长而减少，而贝塔频段保持不变或增加。这些变化在左侧颞叶和左侧额叶区域最大。综上所述，这些发现表明，这些皮质区域在生命的第二个十年正在成熟。左侧顶区的Delta值和theta值随年龄的增加而减少的幅度明显大于右侧。
EEGs were recorded from 32 channels in 30 normal males, ages 16-22. Delta activity decreased throughout this age range. This decrease was greatest in the left frontal and temporal regions; no occipital lead showed this pattern. Relative EEG amplitude analysis, based on normalized maps, revealed decreases with age across alpha, delta, and theta bands with beta staying the same or increasing. These changes were greatest in the left temporal and left frontal regions. Taken together, these findings suggest that these cortical areas are maturing in the second decade of life. Both delta and theta showed significantly greater decreases with age in the left parietal region than in the right.
