Sleep deprivation: effect on sleep stages and EEG power density in man

Abstract

Sleep was analysed in 8 young adults subjects during two baseline nights and two recovery nights following 40.5 h sleep deprivation. Sleep stages were scored from the polygraph records according to conventional criteria. In addition, the EEG records of the entire nights were subjected to spectral analysis to compute the frequency distribution of the power density in the 0.25-25 Hz range for 0.5 Hz or 1.0 Hz bins. In the first recovery night, the power density in the delta band was significantly higher than baseline for total sleep time as well as for sleep stages 2, 3 and 4, 4 and REM. These changes were not restricted to the delta band, but extended to higher frequency bands. Minor, but significant, effects of sleep deprivation were seen in the power density distribution of the second recovery night. In the baseline nights, a progressive reduction of power density in the delta/theta range was present for successive non-REM-REM sleep cycles for total sleep time and stages 2, 3 and 4, and 4. The results show that effects of sleep deprivation as well as trends within the sleep periods are readily apparent from spectral analysis, but are inadequately reflected by conventional sleep scoring. When the power density values were integrated over the entire frequency range (0.75-25 Hz) for each non-REM-REM sleep cycle, an exponential decline from cycle 1 to cycle 3 was suggested. The present findings support the hypothesis that the EEG power density in the low frequency range is an indicator of a progressively declining process during sleep whose initial value is determined by the duration of prior waking.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Reductions in the sigma frequency band are observed under conditions of increased sleep pressure.

    “Rather, a reduction in spectral power within the sigma frequency range was reported [37], with reductions in this frequency band observed under conditions of increased sleep pressure [84,85].”
  • Delta-band power is the dominant frequency band during sleep, increases due to sleep deprivation, and decreases following extended sleep.

    “We suggest this to be the case because, apart from being the dominant frequency band during sleep30, delta-band power reflects the physiological tendency for sleep, by increasing due to sleep deprivation31 and decreasing following extended sleep32.”

  • Sleep deprivation typically reduces spindle activity during subsequent recovery sleep, together with an increase in SWA.

    “Sleep deprivation typically reduces spindle activity during subsequent recovery sleep, together with an increase in SWA (114, 300 -302)”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
