A deep learning software tool for automated sleep staging in rats via single channel EEG [PDF]

open access: yesNPP-Digital Psychiatry and Neuroscience
Poor quality and poor duration of sleep have been associated with cognitive decline, diseases, and disorders. Therefore, sleep studies are imperative to recapitulate phenotypes associated with poor sleep quality and uncover mechanisms contributing to ...

Alterations of Subcortical Brain Structures in Paradoxical and Psychophysiological Insomnia Disorder

open access: yesFrontiers in Psychiatry, 2021
Insomnia disorder (ID) is a common illness associated with mood and cognitive impairments. Subtyping ID is an ongoing debate in sleep medicine, but the underlying mechanisms of each subtype is poorly understood. Growing evidence suggests that subcortical

Paradoxical Sleep Mechanisms [PDF]

open access: yesSleep, 1994
A review of the effects of brain-stem transections, carbachol microinjections and lesions does not show that the pons is necessary and sufficient for paradoxical sleep (PS) generation. The different theories that explain the mechanisms of PS rebound are summarized.

Sleep Education for Paradoxical Insomnia [PDF]

open access: yesBehavioral Sleep Medicine, 2011
This case study series investigated a new treatment for paradoxical insomnia patients as there is no standard treatment for this patient group at this time. Four paradoxical insomnia patients had a polysomnography (PSG) sleep study, an unsuccessful brief course of behavioral treatment for insomnia, and then a novel sleep education treatment comprising ...

Sleep of paradoxes [PDF]

open access: yesThe Journal of Physiology, 2000
In this issue of The Journal of Physiology, Morrell et al. report their findings from a study of the response of human subjects to inspiratory resistive loading during sleep and wakefulness. At issue is a question of physiology in sleep that is important for understanding the pathophysiology of the obstructive sleep apnoea syndrome. These patients, and

Phenotype-based and Self-learning Inter-individual Sleep Apnea Screening with a Level IV Monitoring System [PDF]

open access: yes, 2018
Purpose: We propose a phenotype-based artificial intelligence system that can self-learn and is accurate for screening purposes, and test it on a Level IV monitoring system. Methods: Based on the physiological knowledge, we hypothesize that the phenotype

Differential Effects of an Alpha-2 Agonist on Wakefulness and Paradoxical Sleep in The Rat: A Polygraphic and Biochemical Approach

open access: yesBehavioural Neurology, 1997
The purpose of this experiment was to determine the sensitivity of wakefulness and paradoxical sleep to the α2-agonist, c1onidine. The drug inhibited both wakefulness and paradoxical sleep but the smallest dose necessary to inhibit wakefulness was 64 ...
