1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Sleep involves widespread changes in neural activity, with distinctive oscillatory patterns emerging across frequency bands and brain regions. Characterising these dynamics is essential for understanding their functional roles in health and their disruption in sleep-related disorders. However, most work on healthy humans has used techniques with limited temporal or spatial resolution, focusing mainly on the cerebral cortex. Growing evidence suggests that subcortical and cerebellar structures contribute to sleep dynamics, yet these regions remain largely unexplored in human neuroimaging due to methodological limitations. Magnetoencephalography (MEG) offers millisecond temporal resolution with spatial precision to localise activity across cortical, subcortical and cerebellar regions. Recent evidence demonstrates that MEG can detect signals from deep brain structures, challenging assumptions about its spatial limitations, but systematic validation and whole-brain mapping of oscillatory activity during sleep remain lacking. In this study, we provide comprehensive maps of oscillatory power across the whole brain during non-rapid eye movement (NREM) sleep using source-localised MEG. We first validated signal differentiability across cortical, subcortical and cerebellar regions using spectral fingerprinting analysis. We then characterised frequency-specific and stage-specific changes in oscillatory power across six frequency bands and three NREM sleep stages. Finally, we examined sigma-band dynamics during spindle-rich stage 2 sleep to investigate spindle-related activity across brain regions. Our results reveal structured, region-specific patterns of sleep modulation that extend beyond traditional cortical-thalamic circuits, including novel evidence for cerebellar engagement in fast spindle frequencies. These findings expand models of sleep-related brain activity and demonstrate the utility of whole-brain MEG for understanding distributed sleep networks.
