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.

REM sleep, REM parasomnias, REM sleep behaviour disorder.
Ideggyógyászati szemle, 2022 We review the literature on REM parasomnias, and their the underlying mechanisms. Several REM parasomnias are consistent with sleep dissociations, where certain elements of the REM sleep pattern emerge in an inadequate time (sleep paralysis, hypnagogic ...

Role of corticosterone on sleep homeostasis induced by REM sleep deprivation in rats. [PDF]
PLoS ONE, 2013 Sleep is regulated by humoral and homeostatic processes. If on one hand chronic elevation of stress hormones impair sleep, on the other hand, rapid eye movement (REM) sleep deprivation induces elevation of glucocorticoids and time of REM sleep during the

Molecular Mechanisms of REM Sleep [PDF]
Frontiers in Neuroscience, 2020 Rapid-eye movement (REM) sleep is a paradoxical sleep state characterized by brain activity similar to wakefulness, rapid-eye-movement, and lack of muscle tone.

A moderate increase of physiological CO2 in a critical range during stable NREM sleep episode: A potential gateway to REM sleep [PDF]
Frontiers in Neurology, 2012 Sleep is characterized as rapid eye movement (REM) and non-rapid eye movement (NREM) sleep. Studies suggest that wake-related neurons in the basal forebrain, posterior hypothalamus and brainstem and NREM sleep-related neurons in the anterior-hypothalamic

The Biology of REM Sleep [PDF]
Current Biology, 2017 Considerable advances in our understanding of the mechanisms and functions of rapid-eye-movement (REM) sleep have occurred over the past decade. Much of this progress can be attributed to the development of new neuroscience tools that have enabled high-precision interrogation of brain circuitry linked with REM sleep control, in turn revealing how REM ...

A Hypothalamic Switch for REM and Non-REM Sleep [PDF]
Neuron, 2018 Rapid eye movement (REM) and non-REM (NREM) sleep are controlled by specific neuronal circuits. Here we show that galanin-expressing GABAergic neurons in the dorsomedial hypothalamus (DMH) comprise separate subpopulations with opposing effects on REM versus NREM sleep.

Rapid eye movements during sleep in mice: High trait-like stability qualifies rapid eye movement density for characterization of phenotypic variation in sleep patterns of rodents [PDF]
BMC Neuroscience, 2011 Background In humans, rapid eye movements (REM) density during REM sleep plays a prominent role in psychiatric diseases. Especially in depression, an increased REM density is a vulnerability marker for depression.

REM Sleep and Endothermy: Potential Sites and Mechanism of a Reciprocal Interference [PDF]
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 ...

REM Sleep EEG Instability in REM Sleep Behavior Disorder and Clonazepam Effects [PDF]
Sleep, 2017 We aimed to analyze quantitatively rapid eye movement (REM) sleep electroencephalogram (EEG) in controls, drug-naïve idiopathic REM sleep behavior disorder patients (iRBD), and iRBD patients treated with clonazepam.Twenty-nine drug-naïve iRBD patients (mean age 68.2 years), 14 iRBD patients under chronic clonazepam therapy (mean age 66.3 years), and 21
