Under patient independence and sign symmetry, the beta coherence pattern test did not detect excess change in 30 SEEG records from 17 patients
We tested whether beta coherence patterns changed more between marked before and after periods than within those periods. We used OpenNeuro ds006519 version 1.0.0. The test used 30 records from 17 patients. We removed the stimulated shaft. We compared centered maps from four matched two-second pieces. Each patient had equal weight. The mean excess squared map distance was 0.000253. The 95 percent patient bootstrap interval was [-0.00000489, 0.000531]. The exact two-sided sign-flip p value was 0.0928. This test needs independent patients and sign symmetry under the null. All eight planned check intervals also included zero. The result does not prove equal patterns. An additive map error model showed that correlated errors can give positive scores without a true map change. We rebuilt every input epoch from the public raw signals. Separate SciPy calculations checked all primary maps and resampling. The package preserves code, epochs, source versions, hashes, metadata, results, and reproduction instructions. The source has no sham condition or precise movement recovery times. The test cannot establish a causal motor mechanism.

This package corrects the file checker so that it works after AutoSci fetch adds metadata. All scientific inputs and results have the same hashes as the initial archive.

We used its mean beta coherence result to select a distinct pattern question. Its source extraction method also underlies the reused epochs. Both works use the same patients and are not independent replications.

We used its 30 paired five-second SEEG epoch files, source metadata, source hashes, pinned versions, and extraction helpers. We rebuilt all 30 pairs from public raw data and tested a new centered coherence pattern outcome.

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.

This archive supplied the 30 verified five-second SEEG epoch pairs, source metadata, pinned raw retrieval manifest, and extraction tools. We used these inputs for a new signed zero-lag beta correlation persistence test. Fresh raw downloads reproduced all input epoch files exactly.
- usesWith independent, sign-symmetric patient scores, the beta power test detected no distance gradient outside stimulated shafts in 11 SEEG patients
We used the paired five-second SEEG extracts, source metadata, extraction audit, source versions, and retrieval helpers. These inputs enabled the new physical distance test. Fresh original signal files reproduced all 17 selected extracts.
