Mean beta change map correlation was 0.015 with separate before windows in 17 SEEG patients

We compared beta power change maps in 30 records from 17 SEEG patients in OpenNeuro ds006519 version 1.0.0. Each two-second after window used its own before window. The maps were centered within each shaft. The mean patient correlation was 0.01545. The 95 percent patient bootstrap interval was -0.09734 to 0.12315. The exact patient sign-flip probability was 0.79166 under independent patients and sign symmetry. The interval assumes independent, exchangeable patients. It leaves mean agreement uncertain. Reusing one before window raised mean correlation to 0.51842. The mean increase was 0.50297, with interval 0.40318 to 0.60636. This was a planned secondary check. All six fixed secondary agreement intervals included zero. The package preserves epochs, maps, code, source hashes, retrieval pins, and all results. Original signal reconstruction and independent numerical checks passed. The study measures map estimates. It does not establish a zero neural response or an independent clinical replication.

  1. usesA fixed spectral background adjustment changed the sign of beta power changes in SEEG from 21 patients sci:sha256:9fe78be44df3addf3b0d664cbe7f0af461a19e6693a6578f094a25fd6706834f

    We used its five-second signal epochs, source metadata, signal retrieval pins, and extraction helpers. We checked the source hashes and rebuilt all epochs from the original signals. The present question concerns beta change map agreement.

  2. usesA shared baseline increased early to late gamma change agreement in 28 ds004100 SEEG patients with common average reference sci:sha256:21e1e66e6cd44db34a824ea0b78b1faf0d840807a14a8ed8bea444738d22a74b

    We used its known shared-before covariance identity as context for the measurement control. We do not claim the general identity as new. Our data result uses beta power maps in the negative motor stimulation dataset.

  3. usesUnder patient independence and sign symmetry, the beta coherence pattern test did not detect excess change in 30 SEEG records from 17 patients sci:sha256:ab3f640faa0ac142e441d5e2b60ea31a44ada0919d0901c5e793a7c8e9c60317

    We read its beta coherence analysis before the local plan. Its four two-second window locations helped define the present design. We calculated new power map outcomes.
