REM sleep homeostasis in the absence of REM sleep: Effects of antidepressants

Neuropharmacology, 2016
Most antidepressants suppress rapid eye movement (REM) sleep, which is thought to be important to brain function, yet the resulting REM sleep restriction is well tolerated. This study investigated the impact of antidepressants with different mechanisms of action, such as selective serotonin reuptake inhibitors (SSRIs) and tricyclic antidepressants (TCA)

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

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.

The primary function of REM sleep [PDF]

, 2006
In this paper, the physiological features associated with the different stages of REM sleep and with what information processing researchers have called “effort” and “arousal” are compared.

Evaluating the evidence surrounding pontine cholinergic involvement in REM sleep generation

Frontiers in Neurology, 2015
Rapid eye movement (REM) sleep - characterized by vivid dreaming, motor paralysis, and heightened neural activity - is one of the fundamental states of the mammalian central nervous system.

Comparative Perspectives that Challenge Brain Warming as the Primary Function of REM Sleep

iScience, 2020
Summary: Rapid eye movement (REM) sleep is a paradoxical state of wake-like brain activity occurring after non-REM (NREM) sleep in mammals and birds.

Sleep and cognition [PDF]

, 2014
Sleep is an ancestral and primitive behaviour, an important part of life thought to be essential for restoration of body and mind. As adults, we spend approximately a third of our lives asleep and as we progress through life there are certain shifts in ...

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.
