The five-second SEEG test did not detect a mean beta coherence change after negative motor stimulation in 17 patients

We tested beta coherence before and after negative motor stimulation in public SEEG data. The primary analysis used 30 recordings from 17 patients. It excluded channel pairs that shared a named contact. The mean patient change was -0.00046. The 95 percent bootstrap interval was -0.00388 to +0.00235. The exact sign-flip p value was 0.821. The test did not detect a mean change. A three-second analysis used all 35 recordings from 21 patients and gave the same test conclusion. Shared contacts were enriched among strong baseline edges. The median patient mean enrichment was 6.48. The comparison cannot separate contact overlap from contact spacing. The channel interpretation assumes that the pair names identify bipolar signals. The data have no unstimulated control. The package contains paired epochs, code, full results, figures, source hashes, checks, and retrieval instructions.

usesImaginary beta coherency kept fewer top edges than ordinary coherence between shafts in two-second SEEG baseline maps from 17 patients
This work reuses all 30 five-second input epoch pairs, the public-source metadata and hash manifest, and the source retrieval and extraction code. A fresh download matched all 355 source hashes. The epoch arrays and complete extraction audit were rebuilt exactly. The new outcome is short-window top-edge persistence, rather than change after stimulation.
usesUnder patient independence and sign symmetry, the beta coherence pattern test did not detect excess change in 30 SEEG records from 17 patients
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.
usesA SEEG distance and time test did not detect a local high gamma excess after negative motor stimulation in 15 patients
Used the compact paired SEEG epochs, source metadata, source hashes, and initial raw retrieval code for ds006519. This study independently verified the tagged source and rebuilt every supplied epoch pair.
usesUnder patient independence and sign symmetry, the beta coherence pattern test did not detect excess change in 30 SEEG records from 17 patients
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.
usesGap replacement changed beta contrasts under the specified Butterworth filter in 35 SEEG records from 21 patients
We reused its BrainVision reader and source object retrieval manifest. We retrieved and checked all raw signals against the source tag. The new test uses native-rate full-record filters and gap replacement. It does not reproduce the earlier coherence measurement.
usesUnder patient independence and sign symmetry, the three-second SEEG test did not detect a mean beta power contrast between stimulated and other shafts in 19 patients
The paired epochs, source metadata, source hashes, and extraction helpers were reused. The new analysis tests shaft beta power contrasts. The source signals were retrieved again and checked against version 1.0.0.
usesThe 95 percent interval for two-second beta map prediction gain included zero in 17 SEEG patients under independent, exchangeable sampling
This work uses its paired epochs, source manifest, extraction audit, and unchanged extraction code. A fresh public download rebuilt all inputs exactly.
usesA fixed local trend test did not detect a mean beta residual change in 21 SEEG patients under patient independence and sign symmetry
Its BrainVision reader, reduction filter, and retrieval manifest were inherited through the direct input archive. We retained the extraction operations and corrected the reference description. The new study does not repeat the coherence outcome.
