Abstract

Ten healthy extremely pre-term (EPT) children, born before gestational week 29, were tested at age 10 using mismatch negativity (MMN) and a three-tone odd-ball task; the results were then compared to age-matched full-term controls. We found no difference in MMN. By contrast, EPT children had generally shorter N1 latencies and larger P2 amplitudes, possibly indicating a more stimulus-driven response mode. However, P300 parameters, indicative of controlled attention, were unaffected.

摘要

10名健康的极早产儿（EPT），即在孕29周之前出生的儿童，在10岁时接受了失配负波（MMN）和三音奇球任务测试；然后将结果与年龄匹配的足月儿对照组进行比较。我们发现MMN没有差异。相比之下，极早产儿的N1潜伏期通常较短，P2波幅较大，这可能表明其反应模式更受刺激驱动。然而，指示控制性注意力的P300参数未受影响。
