Dynamics of Slow-Wave Activity During the NREM Sleep of Sleepwalkers and Control Subjects
Bibliographic record
Abstract
STUDY OBJECTIVE: To compare the number and distribution of awakenings from slow-wave sleep (SWS) and both the power and dynamics of EEG slow-wave activity (SWA) in sleepwalkers and controls. Somnambulism is considered to be a disorder of arousal from NREM sleep and related to anomalous SWS and SWA. Power spectral analyses have never been used to quantify patients' SWA across sleep cycles. DESIGN: N/A SETTING: N/A PATIENTS: A polysomnographic study was performed on 15 adult sleepwalkers and 15 age- and sex-matched controls. INTERVENTIONS: N/A MEASUREMENTS & RESULTS: Sleepwalkers had a significantly greater number of awakenings from SWS than did control subjects. Controls showed a greater decrease in SWA across NREM cycles. Sleepwalkers had a significantly lower level of SWA during the first NREM period, where most awakenings take place. CONCLUSION: Sleepwalkers appear to suffer from an abnormality in the neural mechanisms responsible for the regulation of SWS.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
