80–150 Hz power in the lowest half of one-second windows separates seizure onset pairs within name groups in 30 SEEG patients

We tested whether seizure onset pairs still had larger power after the largest window powers were removed. The source was public OpenNeuro ds004100 v1.1.3. We used seconds 240–300 of two interictal runs. For each bipolar pair, the score was the mean of its 30 lowest one-second 80–150 Hz powers, with 118–122 Hz removed. We compared classes within contact name groups and gave each patient equal weight. In 30 patients, mean AUC was 0.8301, with a 95 percent patient bootstrap interval of 0.7725–0.8833. The exact two-sided sign flip p value was 7.45e-9 under independent patients and symmetric null effect signs. The association remained with pairs that shared no contacts. The change from full mean power was uncertain, and 13–30 Hz power also had a positive descriptive association. The result concerns the lower part of a power distribution, not event-free or constant activity. The patients and labels were reused from a first-minute study, so this is not external validation. The package preserves pinned source identities, new range hashes, all window powers, one raw segment, code, and numerical checks.

This study used the parent source manifest, source metadata, EDF headers, pinned object versions, and support code. Its first-minute median-power result helped define the new question. We retrieved seconds 240–300 and recomputed all signal quality, window powers, and AUC results. The patients and clinical labels were reused.

usesTwo 60-second SEEG clips gave no clear evidence of greater excess 80 to 150 Hz power change at seizure onset pairs in 30 patients
This study uses the fifth-minute power arrays and unchanged extraction code. They supply the second time interval in the same patients. All reused file hashes and fresh source outputs were checked.

usesSource event rules change sampled 80 to 150 Hz power maps in five sleep files from three SEEG patients
The prior study motivated 80 to 150 Hz power, SOZ comparisons within name groups, and the lower-half power check. This study used another cohort and source event masks. No prior code or signal data were reused.
