The six largest beta and high-band power windows overlapped more at seizure-onset pairs than at other pairs in the same contact name group in two 60-second clips per patient in 30 SEEG patients
This study tested whether large powers in two bands occurred in the same windows more often at seizure-onset pairs. It used public SEEG from OpenNeuro ds004100 version 1.1.3. Each of 30 patients supplied two 60-second interictal clips. The method selected the six largest one-second powers in each band. Beta was 13 through 30 Hz. The high band was 80 through 150 Hz, with 118 through 122 Hz excluded. The comparison used 196 seizure-onset pairs and 341 other pairs in 69 contact name groups. Each patient had equal weight. The mean overlap was 25.04 percent at seizure-onset pairs and 16.26 percent at other pairs. The difference was 8.78 percentage points. Its 95 percent patient bootstrap interval was 4.77 to 12.95 points. The two-sided patient sign-flip p value was 0.000235. This test assumes independent patients and symmetric differences under the null hypothesis. Five fixed sensitivity checks gave the same direction. Pair ranks had low agreement between clips. All 68 input files were rebuilt from pinned public source ranges. All 748 arrays matched exactly. Separate score and signal checks passed. The package preserves code, data, source records, random assignments, and reproduction instructions. The result is a label association in brief clips. It does not establish a neural cause or clinical benefit. Contact name groups are an unverified proxy for electrode shafts.

This publication informed the contact name group comparison and the weighting of each positive pair within a patient. The new study uses those design choices to test the shared timing of beta and high-band extreme power windows.

This study supplied the beta and high-band window powers, source records, and local timing question. We retrieved all pinned raw ranges again and reproduced the power arrays. We tested new combined ranking models.
- usesAlternate-window maps had higher 80–150 Hz SEEG concentration rank agreement within than between recordings in 34 patients
Used its unchanged window powers, source identities, metadata, quality records, extraction code, and raw example. These inputs enabled the new recording split maps. All reused files matched the parent archive hashes.
- usesIndependent calculations reproduced a test that did not detect an 80–150 Hz window adjacency difference in 30 SEEG patients under numeric pair rules
We read the earlier cross-band selected-window overlap analysis before the local plan. It supplied the local comparison and seizure-onset pair weighting context.
