8 Αυγ 2008 · The primary objective of this investigation was to demonstrate the utility of log-linear and multistate analysis of the sleep hypnogram in evaluating differences in nocturnal sleep structure in subjects with and without SDB.
1 Δεκ 2023 · Sleep stage distribution, sleep cycles, and fragmentation are strong predictors of how an expert interprets a hypnogram. By comparing hypnograms not solely on an epoch-by-epoch basis, but also on these more specific features that drive the evaluation by experts, performance assessment of (automatic) sleep-staging and surrogate sleep trackers ...
This analysis indicates that as SDB severity increases, waking up from Stage 1 or 2 and going from sleep to a lighter sleep (Stage 2 to Stage 1) happen at increasingly quicker rates while the rates of getting deep sleep and REM from the most common Stage 2 decrease.
1 Απρ 2023 · An accumulating body of evidence indicates that sleep is beneficial for learning and memory. Task performance improves significantly after a period that includes sleep, whereas a lack of sleep nullifies or impairs such improvements.
26 Ιουν 2017 · Defining sleep cycles and other features of the hypnogram. We segmented each night’s sleep into cycles, following commonly adopted rules 60. Briefly, a cycle required a minimum of 15 min of NREM sleep (with episodes starting with the onset of N2 or N3 sleep), followed by at least 5 min of REM sleep, with the exception that the first cycle ...
Download scientific diagram | Hypnogram depicting normal sleep in a healthy young adult. Normal nocturnal sleep consists of 4e6 sleep cycles, each lasting around 90 min, during which...
28 Νοε 2016 · The resulting automatically generated sleep hypnogram can help clinicians interpret the spectral display and help researchers computationally quantify sleep stages across participants.
