On the Relative Contribution of Stress and Rapid Eye Movement Sleep Deprivation to the Retention Deficit Following Rapid Eye Movement Sleep Deprivation.
The question of what role, if any, rapid eye movement (REM) sleep plays in memory consolidation has yet to be answered. Those studies which find evidence for a functional role of REM in consolidation do so by comparing REM deprived (REMD) animals, which are subjected to cold, wetness, isolation, …

Neural Dynamics of Mental Imagery, Visual Perception, and Rapid Eye Movement Sleep
… to better understand the functional role of rapid eye movement (REM) sleep, we sought to gain a deeper understanding of the differences between neural activity during REM sleep and during the awake state. We set out to investigate the temporal directionality of communication and coupling in …

Central autonomic control in spontaneously hypertensive rats: a study on phasic phenomena during rapid-eye-movement sleep
… differences between the two sleep states. In non rapid-eye-movement sleep, heart rhythm is under prevalent baroreflex control, whereas in rapid-eye-movement sleep central autonomic commands prevail (Zoccoli et al., 2001). Moreover, during rapid-eye-movement sleep the cardiovascular variables show …

A Mathematical Model of the Sleep-Wake Cycle
… of three distinct states: wakefulness, non-rapid-eye-movement (NREM) and rapid-eye-movement (REM). The process of switching between different states is complex, but a common assumption is that it is regulated primarily by two processes (the circadian and the homeostatic process) via …

Effects of Environmental Temperature on Sleep and Waking in Normal Rats and Rats With Basal Forebrain Damage
… decline in the heat and in the cold. Amounts of rapid-eye-movement (REM) sleep in normal rats vary within the thermoneutral zone defined by minimal metabolic rate--25 to 31(DEGREES)C--peaking toward the upper end of this zone (Szymusiak and Satinoff, Physiol. Behav. 26:687, 1981). Given the …

An Examination of Two Possible Delineations of the REMS-Consolidation Hypothesis.
… similar to those in the arousal state, and rapid eye movements. This stage has been termed "rapid eye movement sleep" (REMS), or "paradoxical sleep" (PS) due to the unusual physiological changes. Perhaps the most intriguing characteristic of REMS is its close relationship to the dream …

The twitcing eye : REM sleep and the emotional brain
… emotion have been linked since the discovery of rapid eye movement (REM) sleep sixty years ago. Sleep, in particular REM sleep and the dreams it harbors, seems to modulate mood, restoring stability to the weary mind. Scientists have struggled to understand this link through the biological study …

Effects of REM Sleep Deprivation on Trigeminal Nerves: Increased Thermal Sensitivity
… rat holding device to measure the effect of rapid eye movement (REM) sleep deprivation on trigeminal nerve sensitivity by measuring changes in response to thermal stimuli. This device is now commercially available and sold as an accessory to the Plantar Test (Ugo Basile). Using my device, I …

Are patients with Parkinson’s disease who have either mild to moderate microsmia, severe microsmia or anosmia clinically different?
… (PDQ39), the Hoehn and Yahr scale (H&Y), the Rapid Eye Movement Behaviour Disorder Screening Questionnaire, (RBD) and the Montreal Cognitive Assessment (MoCA). Results: Seventy-two males and forty females have been recruited for this study. Age ranged from 49 - 89 years (mean age 71 years). …

Investigation of Sleep Neural Dynamics in Intracranial EEG Patients
… in alpha band activity between wakefulness and rapid eye movement (REM) sleep in frontal and temporal regions of iEEG patients. Lastly, we implement an automated sleep scoring method relying on the variations in alpha and delta bands power during sleep which can be applied to large sets of iEEG …

A central medullary circuit regulating REM sleep and pontine waves
Rapid-eye-movement (REM) sleep is a distinct behavioral state best known for its association with vivid dreaming in humans, as well as its theorized role in memory formation and consolidation. REM sleep is composed of tonic features such as hippocampal theta oscillations and skeletal muscle …

RF SENSORS FOR MEDICAL AND CYBER-PHYSICAL INTELLIGENCE

A methodological study of the effect of experimentally induced demand characteristics in research on nocturnal dreams
… woken to report their laboratory dreams during rapid eye movement (stage REM) sleep. Night 1 served as an habituation night (Hall, 1967). On nights 2-7 subjects recorded their home dreams on blank diary forms, from which baseline measures were derived. Night 8 served as the laboratory baseline …

Interactions between anterior thalamus and hippocampus during different behavioral states in the rat by Héctor Penagos.
… of awake immobility, slow wave sleep (SWS) and rapid eye movement sleep (REM). Despite its close functional and anatomical association with the hippocampus, whether or how activity in the anterior thalamus is related to activity in the hippocampus during behavioral states characterized by …

Ethosuximide stabilizes sleep-related oscillations and reduces sleep fragmentation during alcohol withdrawal
… oscillations that occur during the rapid eye movement (REM) and, more importantly, non-REM (NREM) stages of sleep. T-type calcium channels are an important component of the cellular processes that generate and maintain SROs. In two complementary studies, we examined the effects of …

Investigating state-dependent pontine cholinergic activity during REM sleep and P-waves in vivo
Rapid eye movement (REM) sleep is a behavioural state during which phasic deflections in pontine LFP, known as pontine waves (P-waves), occur most prominently. Cholinergic pedunculopontine and laterodorsal tegmental nucleus (PPT/LDT) neurons have been implicated in the generation mechanisms of both …

Regulation of dorsal raphe serotonergic neurons by histamine
… a significant increase in the amount of non-rapid eye movement (NREM) sleep. The data reported here could have important clinical implications in the discovery of novel sleep therapies which target the serotonergic and/or the histaminergic system.
