Abstract

Slow-wave activity (SWA; EEG power density in the 0.75–4.5 Hz range) in non-rapid-eye-movement (NREM) sleep is the primary marker of sleep homeostasis and thought to reflect sleep need. But it is unknown whether the generation of SWA itself serves a fundamental function. Previously, SWA has been implicated in brain plasticity and learning, yet the evidence for a causal role remains correlative. Here, we used acoustic slow-wave suppression to test whether overnight improvement in visual texture discrimination, a form of perceptual learning, directly depends on SWA during sleep. Two groups of subjects were trained on a texture discrimination task (TDT) after baseline sleep, and were tested 24 h later, after a 4 h experimental (EX) sleep episode (with or without SWA suppression), and again after a night of recovery sleep. In the suppression group, SWA during EX sleep was reduced by 30% compared with the control group, whereas total sleep time and REM sleep were not affected. Texture discrimination improved after EX sleep in the control group but not in the suppression group. Moreover, overnight improvement in TDT performance correlated with EEG power density during NREM sleep in the frequency range of SWA (maximum r= 0.75 at 0.75–1.0 Hz) over brain areas involved in TDT learning. We conclude that SWA is an important determinant of sleep-dependent gains in perceptual performance, a finding that directly implicates processes of sleep homeostasis in learning.

  • This type of stimulation applied during early non-REM sleep specifically enhanced <1 Hz slow oscillations and additionally increased frontal slow spindle activity.

    “This type of stimulation applied during early non-REM sleep specifically enhanced Ͻ1 Hz slow oscillations and additionally increased frontal slow spindle activity (10)(11)(12).”

    From About Sleep's Role in Memory (2013) · cites this paper as [10]

    The Results section (“Effects of experimental slow-wave suppression on sleep stages and EEG spectra”; page unavailable) reports that sounds during NREM sleep reduced, rather than enhanced, EEG power at 0.75–3.0 Hz. It reports increased spindle-range power at 13.25–14.0 Hz over the right occipitoparietal cortex, not increased frontal slow-spindle activity. (LLM, conf=0.89)

  • Procedural tasks like visuomotor adaptation and visual texture discrimination also benefit from SWS.

    “The hypothesis has been challenged by findings showing that procedural tasks like visuomotor adaptation and visual texture discrimination also benefit from SWS (10,433,581,582).”

    From About Sleep's Role in Memory (2013) · cites this paper as [10]

  • Reducing SWA during sleep by the presentation of tones suppressed the sleep-dependent improvement in visuomotor adaptation skills and also in texture discrimination skills.

    “Correspondingly, reducing SWA during sleep by the presentation of tones was revealed to suppress the sleep-dependent improvement in visuomotor adaptation skills (691, 692) and also in texture discrimination skills (10).”

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.
