A linear model linked higher sleepiness scores to lower 8-13 Hz alpha reactivity within 56 ds004148 adults across three sessions with session adjustment
In OpenNeuro ds004148 version 1.0.1, posterior alpha reactivity was lower when the same person reported more sleepiness. A linear model used 168 observations from 56 adults across three sessions. It removed person means and common session changes. Reactivity was the closed-eye to open-eye 8-13 Hz power ratio in dB. The slope was -0.473 dB per Karolinska Sleepiness Scale level. The 95% interval from 10,000 person-bootstrap samples was -0.811 to -0.224 dB. All four planned processing checks gave negative slopes. The between-person interval included zero. This was a planned secondary analysis of inherited spectra. The package preserves the local plan, all 360 input spectra, source records, a reusable EEG-KSS table, code, results, and reproduction instructions. Twelve complete source EEG records passed hash checks and reproduced all archived arrays exactly. The evidence supports an association under a linear score model. It does not establish causation or prediction in new people. KSS followed both EEG records, eye-state order was fixed, and source eye-movement removal differed between states.

This work used all 360 posterior window spectra, source hashes, metadata, and extraction code from this publication. These files enabled the new within-person analysis of alpha reactivity and KSS. Twelve complete source records were retrieved again to check the inherited extraction.

- usesA fitted 8-13 Hz alpha score had higher repeat agreement than the eye-state ratio in 38 adults. It did not cancel common gain with fixed windows.
This study linked within-person alpha ratio changes to reported sleepiness in the discovery dataset. It supports treating repeat agreement and state sensitivity as different questions. The present work did not test sleepiness or biological validity of its fitted score.
- usesAdding alpha reactivity change did not lower observed KSS error at one month in 56 ds004148 adults under linear models with equal score spacing and each test person excluded
This publication supplied the 360 verified window spectra, source metadata, scores, and source manifests. Its same-cohort alpha reactivity association motivated the fixed EEG feature. We recomputed features and fitted new models without its fitted coefficients.

- usesThe 95% person bootstrap interval included zero for alpha EEG error reduction at one month after short-term training in 56 ds004148 adults
This work supplied the verified spectral files, source tables, raw retrieval records, and extraction code. Its sleepiness association led to this prediction test.
- usesA linear three-session model did not establish a sleepiness link with the closed-eye 7–13 Hz spectral maximum in 56 adults
Its sleepiness and alpha power result defined the new frequency question. Our secondary power calculation repeated its slope in the same cohort. That agreement is not an independent replication.
