Abstract

Study Objectives: Sleep slow waves behave like traveling waves and are thus a marker for brain connectivity. Across a night of sleep in adults, wave propagation is scaled down, becoming more local. Yet, it is unknown whether slow wave propagation undergoes similar across-night dynamics in childhood-a period of extensive cortical rewiring. Methods: High-density electroencephalography (EEG; 128 channels) was recorded during sleep in three groups of healthy children: 2.0-4.9 years (n = 11), 5.0-8.9 years (n = 9) and 9.0-16.9 years (n = 9). Slow wave propagation speed, distance, and cortical involvement were quantified. To characterize across-night dynamics, the 20% most pronounced (highest amplitude) slow waves were subdivided into five time-based quintiles. Results: We found indications that slow wave propagation distance decreased across a night of sleep. We observed an interesting interaction of across-night slow wave propagation dynamics with age (p < 0.05). When comparing the first and last quintiles, there was a trend level difference between age groups: 2- to 4.9-year-old children showed an 11.9% across-night decrease in slow wave propagation distance, which was not observed in the older two age groups. Regardless of age, cortical involvement decreased by 10.4%-23.7% across a night of sleep. No across-night changes were observed in slow wave speed. Conclusions: Findings provide evidence that signatures of brain connectivity undergo across-night dynamics specific to maturational periods. These results suggest that across-night dynamics in slow wave propagation distance reflect heightened plasticity in underlying cerebral networks specific to developmental periods.

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?

  • Slow oscillatory activity shows an inverted U-shaped trajectory peaking during early adolescence.

    “Subsequently, slow oscillatory activity shows an inverted U-shaped trajectory peaking during early adolescence”

    From Sleep—A brain-state serving systems memory consolidation (2023) · cites this paper as [253]

    The Introduction (p. 3) says slow wave activity reaches its maximum during childhood and declines throughout adolescence, contrary to a peak in early adolescence. The Age groups section (p. 5) places the maximum in the 5–8.9-year age group. (LLM, conf=0.88)

    Checked by a reasoning model — may be wrong.

    Experimental — accuracy not yet measured
  • The inverted U-shaped trajectory of slow oscillatory activity presumably reflects parallel changes in cortical synaptic connectivity and white matter microstructure.

    “which presumably reflects parallel changes in cortical synaptic connectivity and white matter microstructure.253”

    From Sleep—A brain-state serving systems memory consolidation (2023) · cites this paper as [253]

    The Introduction (p. 3) says slow-wave activity peaks in childhood and declines through adolescence, and links slow waves to synaptic connectivity. It also links slow-wave propagation parameters to white matter microstructure, but does not say that the inverted U-shaped trajectory of slow-wave activity reflects parallel changes in white matter microstructure. (LLM, conf=0.83)

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.
