The mean beta decrease was smaller after a log-linear spectral adjustment in separate trials from eight public SEEG recordings
We tested whether selected beta decreases remained below changes in nearby frequencies on separate trials. The source was OpenNeuro ds004473, version 1.0.2. The sample had eight patients with epilepsy, 512 trials, and 819 adjacent contact pairs. Five time blocks separated contact selection from testing, with a 30-second gap. The mean integrated beta change was -0.686 dB. The mean change across beta log-power bins was -0.541 dB. A log-linear fit to changes at 6 to 12 Hz and 34 to 48 Hz predicted -0.492 dB at beta centers. The beta residual was -0.049 dB, with a 95 percent patient bootstrap interval of -0.290 to 0.236 dB. The selected-minus-remaining residual was -0.093 dB. Both planned exact tests had a Holm-adjusted p value of 0.828125. The small group residual does not establish the absence of beta-specific activity. Patients differed, and the fit can include flank rhythms. The package preserves trial spectra, source code, metadata, source pins, raw examples, and repeat instructions. All 1024 freshly retrieved signal ranges matched their pinned hashes. This is a new analysis of an existing cohort, not an independent replication.

This study used the source metadata, version pins, range hashes, raw examples, sampling rules, and EDF helper functions. It retrieved the same sampled windows again and computed new spectra and separate-trial beta contrasts.

- usesA fixed bipolar beta test did not detect a mean keypress timing gain across blocks in eight SEEG patients under independent and symmetric null patient gains
This work supplied verified source metadata, EDF version pins, trial selection rules, contact pairs, and EDF functions. We retrieved new raw ranges and computed new temporal profiles.
- usesThe test did not detect a response time beta gain after training site selection in eight SEEG patients under independent symmetric null patient gains
The verified source metadata, EDF version pins, contact pairs, and trial selection rules originated in this work. We use them through the later common-target package.
- usesSelected SEEG pairs had a 0.03 dB mean high gamma residual on later trials in eight patients under a fixed spectral trend
Uses the archived trial spectra, contact setups, source metadata, pins, and raw examples for a new high gamma test on later trials.
- usesAdding beta phase changed SEEG key side prediction by -0.19 percentage points in a fixed model tested on later trials from eight patients
The later phase coefficient package used this trial and signal extraction lineage. We retained its sampled trial design through the phase package.
- usesPairs selected for low beta change in one cue condition had lower changes than other pairs in the other cue condition in eight SEEG patients
Its spectral adjustment result in the same cohort informed the question and the limits on the raw beta measure before the local plan. Its spectra, code, and numerical results were not inputs to this analysis.
- usesThe adjusted hippocampal fixation theta estimate for prior memory load had an interval that included zero in 14 SEEG patients with linear session trends
The earlier method motivates a fixed log-linear spectral adjustment. This study applies a new theta contrast to another public SEEG dataset. It does not reuse the beta effect estimates.
- usesThe beta phase test did not reject zero at selected SEEG pairs in eight patients under patient independence and sign symmetry
Reused the eight-patient cohort, sampled trial rules, metadata, fixed EDF versions, range hashes, and raw examples. The new phase coefficients came from fresh EDF ranges. Compared beta power changes to the archived prior values as a numeric check. This is a secondary analysis, not an independent replication.
- usesBaseline beta selection within shafts gave a +0.007 dB later mean contrast in eight SEEG patients under a fixed model
This publication supplied all eight trial spectrum files, pair definitions, raw examples, source metadata, source pins, and extraction code. We verified the copied files and rebuilt all spectra from pinned public data. We reused its cohort for a new baseline ranking and a later trial comparison within each shaft.
