Non-REM sleep in major depressive disorder [PDF]
NeuroImage: Clinical, 2022 Disturbed sleep is a key symptom in major depressive disorder (MDD). REM sleep alterations are well described in the current literature, but little is known about non-REM sleep alterations.

Local Aspects of Avian Non-REM and REM Sleep [PDF]
Frontiers in Neuroscience, 2019 Birds exhibit two types of sleep that are in many respects similar to mammalian rapid eye movement (REM) and non-REM (NREM) sleep. As in mammals, several aspects of avian sleep can occur in a local manner within the brain.

Blood pressure dipping during REM and non-REM sleep in patients with moderate to severe obstructive sleep apnea [PDF]
Scientific Reports, 2021 A limited number of papers have addressed the association between non-dipping-blood pressure (BP) obstructive sleep apnea (OSA), and no study has assessed BP-dipping during rapid eye movement (REM) and non-REM sleep in OSA patients.

Structural differences between REM and non-REM dream reports assessed by graph analysis. [PDF]
PLoS ONE, 2020 Dream reports collected after rapid eye movement sleep (REM) awakenings are, on average, longer, more vivid, bizarre, emotional and story-like compared to those collected after non-REM. However, a comparison of the word-to-word structural organization of

REM versus Non-REM sleep disturbance specifically affects inter-specific emotion processing in family dogs (Canis familiaris) [PDF]
Scientific Reports, 2020 Dogs have outstanding capabilities to read human emotional expressions, both vocal and facial. It has also been shown that positively versus negatively valenced dog-human social interactions substantially affect dogs’ subsequent sleep.

Regulation of REM and Non-REM Sleep by Periaqueductal GABAergic Neurons [PDF]
Nature Communications, 2018 The vlPAG in the midbrain is known to suppress REM sleep, but the precise neural correlates are not known. Here, the authors record the activity of vlPAG GABAergic neurons during the sleep–wake cycle and report fast changes at REM sleep transitions and ...

Hibernation in a primate: does sleep occur? [PDF]
Royal Society Open Science, 2016 During hibernation, critical physiological processes are downregulated and thermogenically induced arousals are presumably needed periodically to fulfil those physiological demands.

Journal of International Medical Research, 2022 Objective Rapid eye movement (REM) obstructive sleep apnea (OSA) is associated with the risk of cardiovascular events. Arterial stiffness and carotid artery intima-media thickness (IMT) predict these events, but few relevant studies have been conducted ...
