The first night effect: an EEG study of sleep.
TLDR
The electroencephalographic records from 43 subjects who slept for four consecutive nights in a laboratory environment showed that the first night of laboratory sleep contains more awake periods and less Stage I-rapid eye movement sleep.Abstract:
The electroencephalographic records from 43 subjects who slept for four consecutive nights in a laboratory environment were studied in an effort to describe the First Night Effect. These records showed that the first night of laboratory sleep contains more awake periods and less Stage I-rapid eye movement sleep. There is a delay in the onset of Stages IV and I-REM and the sleep is more changeable. These effects rapidly adapt out by the second night of sleep.read more

The Occurrence of Sleep-Disordered Breathing among Middle-Aged Adults
TL;DR: The prevalence of undiagnosed sleep-disordered breathing is high among men and is much higher than previously suspected among women, and is associated with daytime hypersomnolence.

Sleep-disordered breathing and school performance in children
TL;DR: SAGEA is frequently present in poorly performing first-grade students in whom it adversely affects learning performance and the data suggest that a subset of children with behavioral and learning disabilities could have SAGEA and may benefit from prospective medical evaluation and treatment.

Chapter 2 - Normal Human Sleep : An Overview
TL;DR: In this article, a nightly pattern of sleep in mature humans sleeping on a regular schedule includes several reliable characteristics: sleep begins in NREM and progresses through deeper NREM stages (stages 2, 3, and 4 using the classic definitions, or stages N2 and N3 using the updated definitions) before the first episode of REM sleep occurs approximately 80 to 100 minutes later.

Adolescent Sleep Patterns, Circadian Timing, and Sleepiness at a Transition to Early School Days
TL;DR: Early start time was associated with significant sleep deprivation and daytime sleepiness, and the occurrence of REM sleep on MSLT indicates that clinicians should exercise caution in interpreting MSLT REM sleep in adolescents evaluated on their "usual" schedules.

Estimating sleep patterns with activity monitoring in children and adolescents: how many nights are necessary for reliable measures?

TL;DR: Five or more nights of usable recordings are required to obtain reliable actigraph measures of sleep for children and adolescents and reliability estimates for values aggregated over any 5 nights were adequate for sleep start time, wake minutes, and sleep efficiency.

Cyclic variations in EEG during sleep and their relation to eye movements, body motility, and dreaming.
TL;DR: Records from a large number of nights in single individuals indicated that some could maintain a very striking regularity in their sleep pattern from night to night, and that body movement, after rising to a peak, dropped sharply at the onset of rapid eye movements and rebounded abruptly as the eye movements ceased.

Sleep patterns in young adults: an eeg study.
TL;DR: EEG sleep stages do not appear in any consistent temporal sequence from night to night in a given subject nor in a group of subjects, and the stage change was usually smooth, moving from one stage to the next when sleep was deepening, but less smooth, often “jumping”.

Sleep patterns in the young adult female: An EEG study
TL;DR: Additional support was found for the hypothesis that an individual spends a characteristic mount of time in each sleep stage, and stage changes were usually smooth, moving from one stage to the next when sleep was deepening, but less smooth during arousal from deeper levels.
