Findings are presented in support of the hypothesis that the tendency of sleep rapid eye movement (REM) activity to group into burst structures changes with age during the first year of life in normal infants. Specifically, by assuming a markovian model for the generation of 1 sec long units of REM activity, it is shown that the propensity of those units to develop a sustained clustering pattern may increase during the first 2 months, possibly reaching a plateau at about 4 months. On the other hand, the overall density of REM activity units may continue to increase beyond that point in time.
正常婴儿在出生后的第一年，睡眠快速眼动（REM）活动聚集成爆发结构的倾向会随年龄变化。具体而言，通过假设一个用于生成1秒长REM活动单元的马尔可夫模型，研究表明这些单元形成持续聚类模式的倾向可能在头2个月增加，可能在大约4个月时达到平稳状态。另一方面，REM活动单元的总体密度可能在那个时间点之后继续增加。
