Sleep architecture when sleeping at an unusual circadian time and associations with insulin sensitivity. [PDF]
PLoS ONE, 2013 Circadian misalignment affects total sleep time, but it may also affect sleep architecture. The objectives of this study were to examine intra-individual effects of circadian misalignment on sleep architecture and inter-individual relationships between ...

Optogenetic activation of cholinergic neurons in the PPT or LDT induces REM sleep [PDF]
, 2014 Rapid eye movement (REM) sleep is an important component of the natural sleep/wake cycle, yet the mechanisms that regulate REM sleep remain incompletely understood.

Current Biology, 2020 For many decades, sleep researchers have sought to determine which species ‘have’ rapid eye movement (REM) sleep. In doing so, they relied predominantly on a template derived from the expression of REM sleep in the adults of a small number of mammalian species.

Comparing the cardiac autonomic activity profile of daytime naps and nighttime sleep. [PDF]
, 2018 Heart rate variability (HRV) is a reliable technique to evaluate autonomic activity and shows marked changes across a night of sleep. Previous nighttime sleep findings report changes in HRV during non-rapid eye movement sleep (NREM), which have been ...

REM Sleep and Endothermy: Potential Sites and Mechanism of a Reciprocal Interference
Frontiers in Physiology, 2017 Numerous data show a reciprocal interaction between REM sleep and thermoregulation. During REM sleep, the function of thermoregulation appears to be impaired; from the other hand, the tonic activation of thermogenesis, such as during cold exposure ...

Is REM Density a Measure of Arousal during Sleep?
Brain Sciences, 2023 Rapid eye movements (REMs), an expression of REM sleep phasic activity, occur against a stable background of cortical desynchronization and the absence of axial tone. The significance of REMs during the sleep period was initially attributed to the mental

Sociality Affects REM Sleep Episode Duration Under Controlled Laboratory Conditions in the Rock Hyrax, Procavia capensis. [PDF]
, 2017 The rock hyrax, Procavia capensis, is a highly social, diurnal mammal. In the current study several physiologically measurable parameters of sleep, as well as the accompanying behavior, were recorded continuously from five rock hyraxes, for 72 h under ...

Evening light environments can be designed to consolidate and increase the duration of REM-sleep
Scientific Reports, 2022 Evening exposure to short-wavelength light has disruptive effects on circadian rhythms and sleep. These effects can be mitigated by blocking short-wavelength (blue) frequencies, which has led to the development of evening blue-depleted light environments
