The amount of sleep spindles and K-complexes shows a great interindividual variety of combinations, such as many or few sleep spindles and K-complexes respectively. There seems to be no direct correlation between the amount of sleep spindles and K-complexes intraindividually. In our unselected population - age range between 18 and 77 years - the mean sleep spindle density is at 2.59 +/- 1.85/min and the mean K-complex density at 1.96 +/- .96/min stage 2. The diffuse individual distribution, however, does not reflect the age factor involved. The sleep spindle and K-complex density were practically half the amount for the age group above 50 years as compared to the age group of less than 30 years.
睡眠纺锤波和K复合波的数量呈现出个体间多种不同的组合形式，比如分别有许多或很少的睡眠纺锤波和K复合波。个体内部睡眠纺锤波和K复合波的数量之间似乎没有直接关联。在我们未经过筛选的人群（年龄范围在18至77岁之间）中，睡眠纺锤波的平均密度为2.59±1.85/分钟，K复合波在第二阶段的平均密度为1.96±0.96/分钟。然而，这种个体间的分散分布并未反映出年龄因素。与年龄小于30岁的人群相比，50岁以上年龄组的睡眠纺锤波和K复合波密度实际上只有其一半。
