Independent contact rotations gave higher mean one-second beta power correlations between bipolar signals that share a contact than Gaussian models in 36 SEEG patients
We compared independent contact models for bipolar signals that share a contact. We used 72 short SEEG records from 36 epilepsy patients in OpenNeuro ds004100 version 1.1.3. The rotation model kept recorded contact waveforms and used independent circular shifts and global complex phases. The proper Gaussian model used the same expected contact spectra. For one-second beta power, the equal patient mean correlation was 0.339955 for rotations and 0.250437 for Gaussian models. The paired difference was 0.089519. Its descriptive 95 percent patient bootstrap interval was 0.077309 to 0.102769. All 36 patient mean differences were positive. Some individual path differences were negative. All six fixed additional settings gave positive patient mean differences. These are exact model correlations, not measured brain connections. The package preserves a derivation, sufficient moments, code, raw source recipes, metadata, validation, and results. A full raw rebuild matched all 72 saved record arrays. A repeated analysis matched all score and bootstrap files byte for byte.

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.

This study uses the fixed 36 patient cohort, contact layouts, pinned raw range locks, archived source metadata, and MIT EDF reader. It extends population power moment calculations with finite record test rejection rates. New coefficients and simulations were computed from the pinned public raw bytes.
