Learning‐dependent changes in sleep spindles and Stage 2 sleep

FOGEL, STUART M., SMITH, CARLYLE T.·2006·Journal of Sleep Research

Abstract

Summary: It has become increasingly clear that sleep is necessary for efficient memory consolidation. Recently, it has been found that Stage 2 sleep disruption impairs procedural memory performance, and that memory performance is correlated with the duration of Stage 2 sleep; but the mechanisms involved in synaptic plasticity for procedural memory during sleep have not been identified. The present study examined the learning‐dependent changes in sleep, including Stage 2 sleep spindles. Following an intense period of simple motor procedural learning, the duration of Stage 2 sleep and spindle density increased. There were no changes observed in the duration of any other stage of sleep or in the density of rapid eye movements. These findings support the hypothesis that sleep spindles are involved in the off‐line reprocessing of simple motor procedural memory during Stage 2 sleep.

  • There is consistent evidence for an involvement of stage 2 sleep and sleep spindles in motor learning.

    “There is consistent evidence for an involvement of stage 2 sleep and sleep spindles in motor learning (139,396,822,862,921), and memory for a simple motor task is impaired after selective stage 2 sleep deprivation (1112, 1117).”

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.
