Normally when we sleep , we move through a number of different sleepstages.
2
Each subject underwent one polysomnographic night recording; sleepstages were scored following standard criteria.
3
At birth, babies do not move through sleepstages as they will as adults.
4
Electroencephalographic characteristics of PA during sleepstages are described.
5
Standard sleepstages were assessed, and the EEG was submitted to a state-specific, serial spectral analysis.

1
Time spent in each sleepstage could not account for this relationship.
2
No differences in sleepstage percentages were observed between participants with and without RLS.
3
Those who have spindles also show K-complexes and thus regular phases of sleepstage 2.
4
Average spectra were obtained for each CAP condition, separately in sleepstage 2 and SWS, for each subject.
5
No sleepstage specificity was found.
6
This sleepstage is when you usually dream and is believed to be important for learning and creating memory.
7
The hypothesis that an increase in this sleepstage serves as a mechanism for energy conservation should be also considered.
8
These findings support an association between APOEε4 genotype and sleepstage N3 in the elderly.
9
A novel framework for joint detection of sleep spindles and K-complex events, two hallmarks of sleepstage S2, is proposed.
10
A series of 5-min ECG epochs were chosen from each sleepstage, during periods without evident ictal epileptiform activity in the EEG.
11
However, the involvement of this particular sleepstage in the systemic consolidation of remote (30 days old) memory has never been tested.
12
Conclusions: CAP subtypes are characterized by clearly different spectra and also the same subtype shows a different power spectrum, during sleepstage 2 or SWS.
13
Nine of 17 patients had seizures during the polysomnographic recording; nocturnal ictal events occurred mostly during non-REM sleepstage 2.
14
It is "deeply optimised to track sleepstage monitoring, real-time heart rate monitoring, sleep respiration quality and big data analysis to score sleep quality".
15
Heart rate variability was assessed as a function of the sleepstage at three different ambient temperatures (thermoneutrality and warm and cool thermal conditions).
16
As sleep became deeper in sleepstage 1, beta-2 and beta-3, powers decreased mainly in the frontal lobe and some regions of the parieto-temporo-limbic area.
