Sleep spindles, as defined in the international electroencephalography (EEG) glossary, are distinguished from spindle bursts seen in the EEGs of premature infants. Classical sleep spindles do not occur in prematures. They first appear clearly in the EEG during slow wave sleep from the 4th week postterm (44 weeks conceptional age) and are normally present in all infants' EEGs by 9 weeks postterm. During the first year of life they may be of high voltage relative to their appearance in older children and adults and are commonly characterized by variable degrees of interhemispheric asymmetry and asynchrony. Individual differences are great. Some features of clinical significance are discussed.
根据国际脑电图（EEG）术语表的定义，睡眠纺锤波与早产儿脑电图中出现的纺锤波暴发不同。典型的睡眠纺锤波在早产儿中不会出现。它们在孕40周后第4周（孕龄44周）的慢波睡眠期间首次清晰地出现在脑电图中，到孕40周后第9周时通常会出现在所有婴儿的脑电图中。在生命的第一年，相对于大龄儿童和成人的脑电图表现，它们的电压可能较高，并且通常具有不同程度的半球间不对称和不同步的特征。个体差异很大。文中讨论了一些具有临床意义的特征。
