Effects of thermal environment on sleep and circadian rhythm

open access: yesJournal of Physiological Anthropology, 2012
The thermal environment is one of the most important factors that can affect human sleep. The stereotypical effects of heat or cold exposure are increased wakefulness and decreased rapid eye movement sleep and slow wave sleep.

A Review of Cerebral Hemodynamics During Sleep Using Near-Infrared Spectroscopy

open access: yesFrontiers in Neurology, 2020
Investigating cerebral hemodynamic changes during regular sleep cycles and sleep disorders is fundamental to understanding the nature of physiological and pathological mechanisms in the regulation of cerebral oxygenation during sleep.

Destructive Bruxism: Sleep Stage Relationship [PDF]

open access: yesSleep, 1988
Despite apparent similar amounts of bruxism, two groups that had been evaluated polysomnographically differed dramatically in symptomatology. Patients with severe symptoms were referred to as the destructive bruxism group and were compared with (a) a group with sleep disturbance complaints who had bruxism and (b) a group of insomniac depressed patients

Large-Scale Automated Sleep Staging [PDF]

open access: yesSleep, 2017
Automated sleep staging has been previously limited by a combination of clinical and physiological heterogeneity. Both factors are in principle addressable with large data sets that enable robust calibration. However, the impact of sample size remains uncertain.

Cellular and neurochemical basis of sleep stages in the thalamocortical network

open access: yeseLife, 2016
The link between the combined action of neuromodulators in the brain and global brain states remains a mystery. In this study, using biophysically realistic models of the thalamocortical network, we identified the critical intrinsic and synaptic ...

Ssleepnet: a structured sleep network for sleep staging based on sleep apnea severity

open access: yesComplex & Intelligent Systems, 2023
Sleep stage classification is essential in evaluating sleep quality. Sleep disorders disrupt the periodicity of sleep stages, especially the common obstructive sleep apnea (OSA).

Relation of Adverse Childhood Experiences to Clinical and Patient‐Reported Outcomes for Adults With Sickle Cell Disease: A Registry Study

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Adverse childhood experiences (ACEs) are stressful or traumatic events prior to age 18 that are known to have a lasting impact on individuals’ health and well‐being. There is a gap in understanding the relationship between ACEs and Other Life Stressors and health status for adults with sickle cell disease (SCD).

Automatic sleep staging using ear-EEG [PDF]

open access: yesBioMedical Engineering OnLine, 2017
Sleep and sleep quality assessment by means of sleep stage analysis is important for both scientific and clinical applications. Unfortunately, the presently preferred method, polysomnography (PSG), requires considerable expert assistance and significantly affects the sleep of the person under observation.
