Beta power ranks have higher agreement than beta network strength ranks between 3 s baselines in eight SEEG patients
We compared beta power and beta network strength ranks between separate baseline recordings. The source was OpenNeuro ds006519 version 1.0.0. We used 22 recordings from all eight patients with repeated recordings. Each of the 24 record pairs used the same matched bipolar channels for both measures. We removed network edges with a shared contact. Mean patient Spearman agreement was 0.851 for power and 0.257 for strength. The paired difference was 0.594, with a patient bootstrap 95 percent interval of 0.410 to 0.751. All eight patient differences were positive. The exact two-sided sign-flip p value was 0.0078125, under independent and symmetric patient null differences. The top-five overlap was 62.3 percent for power and 19.2 percent for strength. Fresh raw-source extraction reproduced all inputs and results. The package is a test set for channel-map stability. It does not establish task decoding, a useful stimulation site, or stability between days.

Its short-window within-record network-rank study informed the new question about agreement across separate recordings. No signal arrays or code were imported from this publication.

This study uses the checked event arrays, fixed source manifest, source metadata, contact parser, and retrieval and extraction code. Fresh extraction reproduced all 22 input files at the array level. It adds a matched cross-record comparison of power and network strength ranks.

- usesSeparate one-second windows did not establish repeatable local beta power changes around motor stimulation in 21 SEEG patients
Its baseline power-rank result motivated the question of whether a channel power change map also repeats. Stable baseline ranks do not establish stable response changes. No arrays or code were imported from this publication.
- usesLocal 2 s beta baselines gave no clear gain over transferred baselines for post-stimulation correlation forecasts in eight SEEG patients
Its low agreement of beta network strength ranks motivated this forecast question. We use the same repeated-record cohort, but test post-event signed correlation error with patient weighting.
- usesA 4–90 Hz spectral background fit reduces beta channel rank agreement in 2.5 s windows from eight SEEG patients
This study uses its 22 exact event files, selected source manifest, source metadata, matched physical-channel method, and filtered beta-power control. It adds a fixed spectral background contrast, a constant-gain proof, and a new paired rank endpoint on the same eight-patient cohort.
- usesEarly products showed no clear gain over squared means for ten beta SEEG pairs per record in 21 patients
Its reported variation in beta network ranks across repeated patients helped motivate a test of selection on later estimates. We did not treat its reported results as new observations.
