Five-pulse estimates showed a greater mean 100 to 500 ms rise in repeatable power fraction at 2 to 30 Hz than at 70 to 150 Hz in eight STReEF SEEG runs
We tested whether the late increase in repeatable power fraction differs between two bands in public STReEF SEEG data. The fixed sample has eight patients, 96 conditions, and 6803 bipolar readout instances. All 960 fresh source ranges matched the pinned hashes. We used five pulses per group and corrected the power of their mean with off-diagonal pulse products. At 100 to 500 ms, the low-band minus high-band contrast was 6.84 percentage points. It was positive in 7 of eight patients. The exact two-sided patient sign-flip reference gave p=0.0156250. The descriptive 95 percent patient bootstrap interval was 3.54 to 10.42 percentage points. Fixed checks and every readout outcome are saved. The package includes figures, compact products, source versions and hashes, code, an estimator proof, independent checks, and retrieval instructions. The unbiased common-power claim needs a stable mean and uncorrelated pulse errors. The ratio is not unbiased. Repeatable voltage can include artifact. Before windows are not sham trials. The result does not test BCI accuracy or establish a neural cause.

We used its fixed 96-condition SEEG metadata selection and source-range SHA256 records. We downloaded all 960 source ranges again and computed new spectral products. Its time-domain outcome arrays were not inputs.

- usesA five-pulse SEEG test did not show a clear increase in the 4–30 Hz persistence gap after stimulation in eight people
This report supplied the prior five-pulse repeatable-power question and within-group estimator. We compare within-group and across-group power in a different public dataset with a before-pulse control.
- usesMean 2–30 Hz power correlation across SEEG shafts was lower after pulses in later blocks of five pulses in eight STReEF patients
This is the original archived spectral input source through the direct input publication. Its Fourier definitions and diagonal powers enabled the new shaft correlation test. Its license notice is preserved.
- usesFive calibration pulses selected SEEG pairs with greater later repeatable power fraction change than random selection at 2 to 30 Hz in eight STReEF patients with Hann windows
We used its 96 saved spectral products, fixed SEEG sample, source metadata, spectral code, and audit. These inputs permit the separate calibration and test block selection analysis. We also reproduced its full summary as a compatibility check.
- usesFive-pulse weights with 50 percent covariance shrinkage increased later 2 to 30 Hz SEEG log power variance by 39.0 percent at 100 to 500 ms in eight STReEF patients
This is the original compact spectral source through the direct input lineage. Its Fourier definitions and single-pulse powers enabled the new test. We independently rebuilt every included power from public raw ranges.
- usesThe fixed template power ratio rose by 0.16 dB from before to 100 to 500 ms after pulses at 2 to 30 Hz in eight SEEG patients
We use the fixed SEEG sample, source metadata, pinned range hashes, source utilities, and Fourier power method. We retrieved all selected raw ranges again and added cross-block products for the fixed template audit. The patients and selection are shared.

We used its 96 compact spectral files, fixed SEEG sample, metadata, source pins, and extraction code. We tested a new later pulse variance target.
