The characteristics of sleep spindles as a function of age were studied with an automated analysis system. Five age groups (group 0, 3-5 years; I, 13 years; II, 25-34 years; III, 42-53 years; and IV, 67-79 years) were analyzed. Significant differences in spindle frequency were found between groups 0-I and II-III-IV. The frequency increased with increasing age. No age differences were found in spindle duration. Spindle amplitude reached a peak in the group I subjects, then decreased with increasing age.
使用自动分析系统研究了睡眠纺锤波特征随年龄的变化。分析了五个年龄组（0组，3 - 5岁；I组，13岁；II组，25 - 34岁；III组，42 - 53岁；IV组，67 - 79岁）。发现0 - I组与II - III - IV组之间纺锤波频率存在显著差异。频率随年龄增长而增加。纺锤波持续时间未发现年龄差异。纺锤波振幅在I组受试者中达到峰值，然后随年龄增长而降低。
