Stored and bipolar signals gave opposite theta coupling change estimates in 4 of 8 valid public SEEG sessions
We tested whether theta coupling changes depend on the reference and time segment in OpenNeuro ds006065 version 1.0.0. The data contain nine stimulation sessions from seven people with epilepsy. Eight sessions from six people passed the primary quality rule. We used 80 seconds before and after stimulation and three signal references. The primary measure was debiased squared weighted phase lag index at 4 to 8 Hz. Stored and bipolar signals gave opposite change signs in 4 of 8 valid sessions. Stored and mean SEEG signals gave opposite signs in 0 of 8 sessions. Across two non-overlapping 40-second samples, signs matched in 6 of 7 bipolar comparisons and 1 of 7 stored-reference comparisons. 24 of 24 primary sampling intervals included zero. These are estimates from short recordings. They do not establish a causal stimulation effect or show that one reference is correct. The package preserves derived signal data, source versions and hashes, fixed analysis rules, code, tables, figures, and independent estimator checks.

- usesA fixed spectral adjustment changed the sign of theta power change estimates in 2 of 8 valid SEEG rest sessions
We used its 18 archived rest excerpts, contact map, and source range records. We checked the source ranges again. We tested theta power changes with a fixed spectral adjustment. This is a different question from its coupling analysis.
- uses80 percent overlap of 4 second Hann windows raised 4 to 8 Hz dwPLI2 in independent phase controls from 18 public SEEG excerpts
This publication supplied the 18 signal excerpts, contact rules, retrieval code, and source audits. The new work tests independent phase controls and window-pair rules in the same 7 people. It does not use the parent as an independent confirmation.
- usesA past amplitude rule reduced mean 50 ms theta phase error for sine forecasts in seven patients' SEEG rest data and random phase controls
This study supplied the pinned source metadata, byte-range hashes, and contact names. We used them to retrieve native samples and build a new phase forecast benchmark.
- usesAcross 7 people, released and bipolar theta connectivity changes had a median rank correlation of 0.038 in 96 second SEEG rest samples
This result supplied prior evidence of reference and time sensitivity at selected contacts in ds006065. We used it to interpret the broader spatial comparison and define its added scope. No code or derived data were reused.
- usesA fixed test did not detect extra theta phase lag agreement in adjacent epochs of public bipolar SEEG data from six participants
Supplied 18 compact SEEG signal extracts, source records, contact selection, pinned object versions, and the licensed range decoder. All extracts were checked against newly fetched source ranges. Fourier outputs were used only for preprocessing verification.
