Fixed quality rules keep four of nine 96-second SEEG rest pairs with at least ten epochs per file in ds006065
We tested whether local bipolar reference changes theta lag synchrony before and after stimulation. We used public SEEG data from seven patients and nine sessions. The fixed rules rejected epochs with voltage above 500 microvolts or Pearson kurtosis above 5. Each file needed ten accepted epochs. These rules kept four pre/post pairs from three patients. The mean reference effect on the change was 0.0302, with exact p = 0.50. The planned test without voltage and kurtosis rejection kept all seven patients. Its mean was 0.0010, with p = 0.9375. Both references gave the same change sign in all nine sessions in that test. All session uncertainty intervals included zero. An added line-filter test restored one excluded pair. The small sample does not establish reference equivalence or a stimulation effect. The package contains selected signals, source versions and hashes, code, quality masks, results, and repeat instructions.

- usesSimulated responses at three theta RMS changed six-cycle 7 Hz wavelet phase estimates 20 ms before events in 18 fixed SEEG rest clips
We used its original fixed clip boundaries and contact selection through the preserved parent package. The new outcome measures phase changes caused by known future signals.
- usesCross-trial estimates of 50–250 ms response energy were negative in 9 of 18 bipolar SEEG files from ds006065
This publication supplied the first site mapping and a retrieval pattern. We checked the mapping against the original source code and retrieved the pulse files independently.
- usesAmplitude equalization reduced the concentration of 4–10 Hz lag weights in 18 fixed SEEG rest clips
We reused the 18 selected SEEG voltage arrays, pinned source records, fixed contact map, clip boundaries, and quality rules. We adapted its MIT-licensed retrieval recipe. All 18 original bipolar file estimates match the parent finite, nonflat estimates. The new question concerns amplitude weights in the same patients.
- usesThe patient median finite-trial energy fraction was 80.7% for random eight-pulse SEEG averages at 50 to 250 ms in six patients after a 500 microvolt gate
This publication supplied the preserved original MATLAB code archive and the published sensing-contact map. We used them to select SEEG contacts and reconstruct probe epochs. We did not analyze its rest signals or use its rest results as evoked-response evidence.
- usesSpatial theta-to-beta rest changes have mixed signs in five retained ds006065 patients
Uses the source manifest, contact map, fixed sample intervals, and interval hashes. This work retrieves all contacts on the selected probes and tests spatial theta-to-beta power changes.
