Cortical and cervical somatosensory evoked potentials (SEPs) were studied by the averaging method in twenty healthy children, aged 20 days to 3 years. The stimulus was applied to the median nerve at the wrist and SEPs were recorded by electrodes placed on to the contralateral parietal scalp region as well as over the skin at the C6-7 vertebral region. The reference electrode was placed at the Fz. All subjects were studied during the awake state as well as during the N-REM sleep. The results indicate that N-REM sleep influenced the latency and the duration of SEPs, especially in children aged less than one year. This finding probably reflects a variable rate of maturation of the somatosensory pathway. The state of wakefulness must therefore be taken into account when assessing the pathological relevance of SEP recording in young children.
采用平均法对20名年龄在20天至3岁的健康儿童进行了皮质和颈段体感诱发电位（SEP）研究。刺激施加于手腕处的正中神经，通过置于对侧顶叶头皮区域以及C6 - 7椎体区域皮肤上方的电极记录SEP。参考电极置于Fz。所有受试者均在清醒状态以及非快速眼动睡眠期间进行研究。结果表明，非快速眼动睡眠影响SEP的潜伏期和时长，尤其是在1岁以下儿童中。这一发现可能反映了体感通路成熟速率的差异。因此，在评估幼儿SEP记录的病理相关性时，必须考虑清醒状态。
