One second beta power averaging retained shared contact correlation in independent stationary proper complex Gaussian models fitted to 36 SEEG patients

We tested whether beta power averaging removes correlation between bipolar signals that share a contact. We fitted independent, stationary, proper complex Gaussian contact models to 72 public records from 36 SEEG patients in OpenNeuro ds004100 v1.1.3. The mean patient value was 0.2406 after one second averaging and 0.2398 for unsmoothed power. The paired change was +0.00079. A population formula shows that shared contact correlation stays positive at every finite width when shared contact power is positive. Equal powers and spectra give 0.25 at all widths. The package preserves spectra, source code, pinned source recipes, a raw fixture, results, and validation. These model values are not measured brain connections or clinical results.

This study uses its ds004100 v1.1.3 source cohort, pinned 64 second EDF retrieval recipe, source metadata, contact selection, consecutive contact montage, and MIT licensed retrieval code. Raw ranges were downloaded anew. Beta spectra and power averaging endpoints were computed anew. Its covariance results were not used as these endpoints.

Its two record Gaussian control result motivated the question about power averaging. This study tests averaging widths in another cohort. No data files, numerical results, or analysis code from that publication were reused.

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 independent Gaussian power averaging result and shared contact formula informed the comparison with measured contact power moments. We used a new exact finite-block spectral fit and did not reuse its numerical spectra or scores.
usesMean residual beta power map similarity was positive across two 64-second SEEG windows in 35 patients
The fixed shaft selector uses the public contact and adjacent pair lists from this source. The package preserves their compact columns and original file hashes. No spectral density values are used.

usesMean beta power correlation was more than its phase control value in 36 patients with short interictal SEEG records
We used its source recipes, metadata, and contact and pair lists. We calculated new beta coefficients and power correlations from fresh checked source ranges.
usesRemoving six high-energy seconds gave mixed gains against random removal for calibrated 1–80 Hz SEEG maps in 36 patients
The EDF decoder and original retrieval code were copied through publication 9379eca1-07c1-4577-9c93-2a0da823142d. These functions enabled maps from verified raw ranges.
usesA median cap changed mean beta phase-lag rank agreement by -0.022 between paired 60-second intervals in 35 SEEG patients
The retained contact labels, adjacent pair indices, and EDF indices came from this publication through the shaft selection parent. We did not use its spectral values in the new scores.
usesBeta phase-slope pair detail increased mean relative prediction error at weight 0.5 for two 60-second SEEG samples in 36 patients
This work supplied the original eligible contact labels, contact-pair indices, and EDF indices through the compact lists in the input publication. We used these lists to repeat the fixed shaft selection. We did not use its model outcomes or spectral values.
usesClipping at three robust scale units reduced mean calibrated prediction error for recorded 1–80 Hz SEEG correlation maps in 36 patients
This work supplied the pinned public source recipe, eligibility rules, metadata, raw-data example, and reviewed retrieval and EDF decoding code. We downloaded all 72 source excerpts anew and calculated new clipping and Pearson maps. Its beta power and simulation results did not enter our endpoint.
