Thermophysiology and sleep : a comparison between women with and without vascular dysregulation and difficulties initiating sleep [PDF]
, 2008 Temperature and sleep are closely interrelated. The fall of core body temperature (CBT) at the end of the waking period is caused by heat loss via distal vasodilatation, (warm hands and feet). This process induces sleepiness.

The European starling (Sturnus vulgaris) shows signs of NREM sleep homeostasis but has very little REM sleep and no REM sleep homeostasis [PDF]
, 2020 Most of our knowledge about the regulation and function of sleep is based on studies in a restricted number of mammalian species, particularly nocturnal rodents. Hence, there is still much to learn from comparative studies in other species.

GABA neurons in the ventral tegmental area regulate non-rapid eye movement sleep in mice
eLife, 2019 Sleep/wakefulness cycle is regulated by coordinated interactions between sleep- and wakefulness-regulating neural circuitry. However, the detailed mechanism is far from understood.

A probabilistic model for the ultradian timing of REM sleep in mice.
PLoS Computational Biology, 2021 A salient feature of mammalian sleep is the alternation between rapid eye movement (REM) and non-REM (NREM) sleep. However, how these two sleep stages influence each other and thereby regulate the timing of REM sleep episodes is still largely unresolved.

Effects of social stimuli on sleep in mice: non-rapid-eye-movement (NREM) sleep is promoted by aggressive interaction but not by sexual interaction [PDF]
, 2001 Sleep is generally considered to be a process of recovery from prior wakefulness. In addition to being affected by the duration of the waking period, sleep architecture and sleep EEG also depend on the quality of wakefulness.

NREM Sleep Parasomnias Commencing in Childhood: Trauma and Atopy as Perpetuating Factors
Clocks & Sleep, 2022 Objective/Background: Phenotyping of non-rapid-eye-movement (NREM) parasomnias is currently poorly undertaken. This study aimed to determine whether there are differences phenotypically among childhood-, adolescent-, and adult-onset NREM parasomnias ...

Neurophysiology of Avian Sleep: Comparing Natural Sleep and Isoflurane Anesthesia
Frontiers in Neuroscience, 2019 Propagating slow-waves in electroencephalogram (EEG) or local field potential (LFP) recordings occur during non-rapid eye-movement (NREM) sleep in both mammals and birds.

Lucid dreaming during NREM sleep: Two case reports [PDF]
, 2012 Lucid dreams – dreams in which the dreamer is aware that is dreaming – most frequently occur during REM sleep, yet there is some evidence suggesting that lucid dreaming can occur during NREM sleep as well.

Examining First Night Effect on Sleep Parameters with hd-EEG in Healthy Individuals
Brain Sciences, 2022 Difficulty sleeping in a novel environment is a common phenomenon that is often described as the first night effect (FNE). Previous works have found FNE on sleep architecture and sleep power spectra parameters, especially during non-rapid eye movement ...

Sleep deprivation in bright and dim light: antidepressant effects on major depressive disorder [PDF]
, 1990 Twenty-three patients with a major depressive disorder were deprived of a night’s sleep twice weekly, one week staying up in the dimly lit living room of the ward (< 60 lux), and one week in a brightly lit room (> 2000 lux).
