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

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

A continuum model for the dynamics of the phase transition from slow-wave sleep to REM sleep [PDF]
, 2010 Previous studies have shown that activated cortical states (awake and rapid eye-movement (REM) sleep), are associated with increased cholinergic input into the cerebral cortex.

Differential Function of Melatonin MT1 and MT2 Receptors in REM and NREM Sleep
Frontiers in Endocrinology, 2019 The pathophysiological function of the G-protein coupled melatonin MT1 and MT2 receptors has not yet been well-clarified. Recent advancements using selective MT1/ MT2 receptor ligands and MT1/MT2 receptor knockout mice have suggested that the activation ...

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.

Dynamic Network Activation of Hypothalamic MCH Neurons in REM Sleep and Exploratory Behavior
Journal of Neuroscience, 2019 Most brain neurons are active in waking, but hypothalamic neurons that synthesize the neuropeptide melanin-concentrating hormone (MCH) are claimed to be active only during sleep, particularly rapid eye movement (REM) sleep. Here we use deep-brain imaging

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.

Loss of REM sleep features across nighttime in REM sleep behavior disorder [PDF]
Sleep Medicine, 2016 Melatonin is a chronobiotic treatment which also alleviates rapid eye movement (REM) sleep behavior disorder (RBD). Because the mechanisms of this benefit are unclear, we evaluated the clock-dependent REM sleep characteristics in patients with RBD, whether idiopathic (iRBD) or associated with Parkinson's Disease (PD), and we compared findings with PD ...

Nursing Open, EarlyView., 2023 Abstract Aim This study aimed to examine the association of job‐related stressors and insomnia; to determine the association of psychological capital and insomnia; and to explore whether psychological capital mediates the association between job‐related stressors and insomnia among Chinese nurses. Design A cross‐sectional questionnaire survey.
