Supplied ripple overlap marks had a higher mean local 0.5 to 2 Hz phase score in 14 sleep records from eight SEEG patients under block timing controls

We compared supplied ripple marks with and without fast-ripple overlap in public SEEG data from OpenNeuro ds003498 1.1.1. A plan saved before phase analysis selected 15 sleep records from eight patients. The primary test used 75 pair-record cells and local 0.5 to 2 Hz phase. We corrected pairwise phase consistency with 999 timing controls in 28-second blocks. Patients had equal weight. The mean class difference was 0.169953. Its descriptive 95 percent patient bootstrap interval was [0.105362, 0.223012]. The two-sided patient sign-flip p value was 0.015625. Overlap marks had a higher mean local score in the tested records. The descriptive patient interval did not include zero. We report every patient and all five planned sensitivity tests. The score can reflect sharp waves and filters. It does not identify a neural state or validate pathology. The SEEG scope uses source depth-implant descriptions despite ECOG channel labels and assumes matching source patient numbers. The package preserves 50 Hz voltage, mark tables, source hashes, raw retrieval instructions, code, control scores, figures, and a byte-identical offline rebuild.
