Under a block shift model, adjusted 25 ms HFO maps had a mean cosine of 0.502 across dates in seven SEEG patients

We tested whether HFO coincidence maps between separate SEEG shafts repeat across recorded dates. We used 135 five-minute records from seven patients in OpenNeuro ds003498 version 1.1.1. The primary marks were ripples that overlapped fast ripples on the same bipolar channel. We counted start pairs within 25 ms and subtracted an exact expectation from independent shifts within 30-second blocks. We scaled counts and removed fitted shaft and hemisphere pair effects. The mean cosine between early and late residual maps was 0.502; six patient scores were positive. The descriptive 95% patient bootstrap interval was 0.030 to 0.849. A conditional shaft label permutation test gave a two-sided Monte Carlo p value of 0.00102. That test assumes exchangeable late shaft identities within each hemisphere, conditional on the maps. All eight fixed checks gave positive group means. Independent checks passed, and a complete second run matched all 15 numeric files byte for byte. The package preserves source marks, metadata, code, results, figures, hashes, and retrieval instructions. Stable anatomy, electrode placement, and detector effects can contribute to correspondence. The evidence does not establish neural communication or clinical benefit.

    We read its coincidence and resection comparison before the local plan. It informed the choice to study map repeatability without a clinical outcome claim. Both studies use patients from the same source cohort.

    We read its cross-date onset-order direction study before the local plan. It informed the distinct question about undirected residual edge maps. The shared cohort prevents an independent replication claim.
