• usesBeta power before the go cue did not improve later ridge RT prediction beyond context in eight ds004473 patients

  We adapted its EDF header parser and checked byte-range reader to retrieve new signal windows.

• usesIndependent contact phases give positive beta envelope correlation between bipolar channels that share a contact in eight SEEG recordings

  We used its contact spectra, selected montage, and pinned source records. We added envelope measures and a fourth moment model on the same samples. New source downloads checked the inputs.

• usesImaginary coherency reduced beta null rejection for shared-contact bipolar edges in an independent contact phase model of eight SEEG recordings

  Used all 48 saved contact Fourier arrays, montage metadata, pinned source records, and source readers. All 48 raw range hashes and 70 metadata blobs were checked again. The new work adds calibration for four phase statistics and a specified phase-lag control.

• usesIndependent contact shifts retain a positive mean fourth-order beta power term on shared bipolar edges in eight SEEG recordings

  We reused its 48 compact contact spectra, montage map, fixed sample plan, source metadata, and retrieval code. We retrieved the original ranges again and verified the spectra. The new endpoint is the fourth-order power term under contact shifts and contact phases, rather than the earlier voltage correlation.

• usesPhase changes after bipolar subtraction reduced pooled beta imaginary coherency rejection rates in independent contact phase models of eight public SEEG records

  The earlier package supplied contact Fourier coefficients, montage definitions, and a pinned source retrieval recipe. This study checked those inputs and used them for a new imaginary coherency calibration test.

• usesOutput phase controls give higher mean beta imaginary cross-spectrum null variance on shared-contact bipolar edges under independent contact phases with fixed amplitudes in eight SEEG recordings

  This publication supplied six fixed samples per patient, native contact Fourier coefficients, channel metadata, and retrieval and conversion code for all eight ds004473 SEEG patients. We used those inputs to derive and test imaginary cross-spectrum null variance. We downloaded all source ranges again and reproduced the retained coefficients.

• usesIn eight SEEG patients, long pre-cue 20 Hz power events occupied 14.59% of bins compared with 14.67% in phase controls

  We used its EDF header and byte range helper through the direct parent. Our phase controls are common to all bipolar pairs within a trial.

• usesOutput phase tests have a mean 70.89 percent rejection rate at nominal 5 percent for two step Laplacian beta pairs in eight SEEG models with independent contact phases

  This study uses the 48 source spectral files, contact list, source plan, source metadata, and retrieval recipe from this publication. Fresh source range checks verified every spectral file. The new work tests a Laplacian reference and exact rank calibration.

• usesBeta power before the go cue did not improve later ridge RT prediction beyond context in eight ds004473 patients

  We adapted its EDF header parser and checked byte-range reader to retrieve new signal windows.

• usesIndependent output phases reduced 13 to 30 Hz test rejection at shared bipolar SEEG edges under independent contact phases in eight recordings

  This archive supplied the contact spectra, montage, contact flags, source metadata, and pinned byte ranges. We tested imaginary coherency on the same signal sections.

• usesMean later log RT squared error reduction was -0.332 percent with added 20 Hz burst features in eight SEEG patients

  We used its EDF header and range methods through the direct parent helper to retrieve new signal windows.

• usesMasking shared contact edges leaves nonzero partial correlation in consecutive bipolar SEEG paths with four or more independent contacts and finite positive variances

  This publication supplied 48 Fourier samples, eight contact montages, source metadata, and pinned raw range records. We used these inputs to test partial correlation under independent contacts. A separate reader downloaded all 48 raw ranges again and reproduced every saved array field.

• usesIndependent contact models from eight patients gave nonzero five-lag prediction gains for shared-contact bipolar SEEG at 1–45 Hz

  We used the contact montage and pinned source range recipe for eight patients. We retrieved the source ranges and extracted spectra from 1 Hz to below 45 Hz. The prior spectra also checked the extraction over 4 Hz to below 30 Hz.

• usesOne bipolar bridge gave nonzero cross-shaft partial correlation in eight SEEG models with uncorrelated contacts and finite positive variances

  This earlier study produced the contact spectra and source retrieval records used through the direct parent. This run retrieved all 48 pinned raw ranges and reproduced those spectra exactly.
