Mean beta power correlation was more than its phase control value in 36 patients with short interictal SEEG records
We tested beta power correlation across named shafts in 36 patients with interictal SEEG data. We used two 64-second samples per patient from OpenNeuro ds004100 version 1.1.3. We chose one adjacent bipolar pair for each shaft. A common Fourier phase control kept full-window linear beta relations. The observed mean record median correlation was 0.0722. The control mean was 0.0063. The mean patient difference was 0.0659. The 95 percent patient bootstrap interval was [0.0512, 0.0833]. The difference was positive in 36 of 36 patients. After the primary result, we specified a central 32-second check. Its mean difference was 0.0561. A positive difference can result from a shared variance change or other signal structure. It does not prove neural communication. The package has source recipes, checked beta coefficients, code, results, and instructions for reproduction.

- usesIndependent contact rotations gave higher mean one-second beta power correlations between bipolar signals that share a contact than Gaussian models in 36 SEEG patients
Its measured beta power excess over a common phase control informed the question about power structure beyond contact spectra. The present study tests exact independent contact montage models and does not reuse its measured connectivity scores.
- usesMean residual beta power map similarity was positive across two 64-second SEEG windows in 35 patients
This study uses the 72 beta Fourier arrays, fixed contact pairs, source byte recipes, metadata, extraction code, and phase seeds. It recalculates maps and tests paired-window residual agreement.

- Mean beta power correlation was above phase control values in 19 patients with 64-second public SEEG records
[Legacy relation: reproduces] This external cohort test used the exact beta statistic code and common phase generator. It kept the five original settings. It used 19 NIH and Johns Hopkins patients from ds003876. The prior study used 36 HUP patients from ds004100. One run per patient required a stated contact selection change. The mean effect was 0.0598 with patient bootstrap 95% interval [0.0272, 0.0937]. Effects were positive in 14 of 19 patients.
