Refuting a Temporal Correlation: Interictal Epileptic Discharges Do Not Preferentially Occur During Respiratory Events in Patients With Sleep‐Related Breathing Disorder and Epilepsy

open access: yesJournal of Sleep Research, EarlyView.
ABSTRACT The bidirectional interaction between sleep and epilepsy is well known. In particular, it has been established that sleep apnea can worsen epilepsy, whereas sleep apnea (SA) treatment has a beneficial effect on seizure control. However, the exact mechanisms whereby SA promotes epileptic seizures are unknown.

Wearables as Translational Physiomarkers and Clinical Endpoints in Insomnia Research: Can Sleep Research Advance Psychiatry?

open access: yesJournal of Sleep Research, EarlyView.
ABSTRACT Wearables that integrate actigraphy and pulse photoplethysmography (ACT + PPG) could represent a promising advancement in insomnia research and clinical practice. This especially applies to assessing objective sleep for a longer period in the home environment, which is impractical with ambulatory polysomnography (PSG) whereas actigraphy alone ...

The Sleep Opportunity, Need and Ability (SONA) Theory

open access: yesJournal of Sleep Research, EarlyView.
ABSTRACT ‘How much sleep does one need?’ is a critical question that has been difficult to answer. The long history of sleep research has culminated in population‐derived normative values of 7 to 9 h of sleep per night to avoid dysfunction. Such a wide range is sufficiently large that one cannot know what is required for any given individual.

Bidirectional Predictors Between Neurobehavioural Measures During Total Sleep Deprivation and Baseline and Recovery Sleep Measures

open access: yesJournal of Sleep Research, EarlyView.
ABSTRACT For the first time, we examined bidirectional predictors between baseline night (B2) and recovery night 1 (R1) actigraphic sleep measures and neurobehavioural indices during total sleep deprivation (TSD) in a 5‐day experiment with 32 healthy adults. During the B2 and R1 nights, wrist actigraphy assessed sleep indices. Neurobehavioural measures

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 hallucinations and cataplexy) or are absent/partial in their normal REM sleep time (REM sleep without

REM sleep and memory

Current Opinion in Neurobiology, 2017
Memory consolidation, a process which stabilizes recently acquired information into long-term storage, is thought to be optimized during sleep. Although recent evidence indicates that non-rapid-eye movement sleep (NREMs) is directly involved in memory consolidation, the role of rapid-eye movement sleep (REMs) in this process has remained controversial ...

REM-sleep timing is controlled homeostatically by accumulation of REM-sleep propensity in non-REM sleep

American Journal of Physiology-Regulatory, Integrative and Comparative Physiology, 1994
Sleep structure in the rat was characterized during uninterrupted full-day recordings using an analytic procedure that identifies rapid eye movement (REM) sleep episodes based on REM-sleep-onset electroencephalograph phenomena, hence independently of REM-sleep duration.

REM Sleep Parasomnias

Neurologic Clinics, 1996
The three states of mammalian being--wakefulness, REM sleep, and NREM sleep--are not mutually exclusive and may occur simultaneously, oscillate rapidly, or appear in dissociated or incomplete form to produce primary sleep parasomnias. Dysfunctions of a wide variety of organ systems may take advantage of the sleeping state to declare themselves ...

Forerunners of REM sleep

Sleep Medicine Reviews, 2012
The development of sleep research can be divided into two main periods. The first one was initiated in 1863 by the first systematic measurement of the depth of sleep, the second in 1953 by the discovery of recurrent episodes of rapid eye movements in sleep.

Dreaming without REM sleep

Consciousness and Cognition, 2012
To test whether mental activities collected from non-REM sleep are influenced by REM sleep, we suppressed REM sleep using clomipramine 50mg (an antidepressant) or placebo in the evening, in a double blind cross-over design, in 11 healthy young men. Subjects were awakened every hour and asked about their mental activity.
