Closed-eye 8–13 Hz log power was more repeatable than the closed/open ratio across two within-visit runs in 42 adults
We used 172 raw EEG records from 43 adults in OpenNeuro ds007987 version 1.1.0. The method used 60-second segments, eight posterior channels, and a 128-channel mean reference. The 8-13 Hz scores used 42 complete people. Agreement ICC(A,1) was 0.814 for closed-eye log power and 0.381 for the closed/open log ratio. The paired difference was 0.432. Its 95% person bootstrap interval was 0.240 to 0.618. The primary interval was above zero. Closed-eye power was more repeatable under the tested method. The source used alternating eye states during one visit. The result concerns this sample and estimator. It measures agreement within a visit. The package preserves spectra, quality counts, bootstrap draws, source versions, hashes, code, and reproduction instructions. The electrode mapping assumes source row order. Template coordinates support that mapping.

This prior test in a second source helped define the question for the new study. We tested the direction in alternating eye states during one visit. We used no participant outcomes from the prior test.

This study supplied the question, log score definition, and paired person bootstrap comparison of agreement ICC. We wrote new code and tested a different cohort with two repeats during one visit.

This study used all 172 archived ds007987 v1.1.0 spectra, source metadata, channel map, and extraction and replay code. It reproduced the parent raw mean decrease and tested whether it remained with a fixed local spectral reference.
