Eight high-gamma SEEG pairs selected with ten seconds had 76.7% mean retention across two interictal records in 36 patients

1. supersedesEight high-gamma SEEG pairs selected with ten seconds had 76.7% mean retention across two interictal records in 36 patients sci:sha256:44033af8beae820654fad64542bdc6b26b1964e195213c18bc10ddb830e02b8d

   The source label is interictal. This label does not establish wake, sleep, or rest. The first publication used the word resting. This version uses interictal. The source data, analysis, and numerical results are unchanged. The local plan is preserved as written. Its wording does not establish a behavior state.

2. usesThree pairs selected in record A had lower mean AUC than all eligible shafts for the first 20 seizure seconds in record B from 28 SEEG patients sci:sha256:3fa7179f302efe44bd733bd5b0bed5136c22758097888ff97a9c572a3dd61916

   The prior three-pair seizure-state selection result motivated a separate test of interictal power ranks. This study uses eight pairs and interictal records without state labels.

3. usesLocal calibration lowered mean pre-onset window alerts from 25.6% to 8.8% for a median monitor in 28 SEEG record pairs after onset shafts were excluded sci:sha256:3f75c11b0a1b56a89e441827aad7b6b86812d0548cc966f8a1c9eea17cc7bd0e

   The calibration-transfer question and the rule for removal of a whole seizure-onset contact prefix informed this fixed test. New features came from separate interictal source retrieval.

   The analyzed interictal records came from the version 1.1.3 snapshot of the HUP iEEG Epilepsy Dataset.

• usesTen seconds of calibration on other shafts gave no clear decrease in later SEEG high-gamma power error in 36 patients

  Provides the exact 36-patient, 72-record bipolar power archive, native audit samples, frozen source metadata, and retrieval code used in the new absolute-power calibration test.

• usesEight SEEG pairs on eight shafts gave lower mean relative 70–110 Hz test power in 36 epilepsy patients

  Uses the original EDF parser and frozen cohort recipe inherited through the parent feature publication. Preserves and reruns the parser.

• usesLinks with a shared contact had a larger share of strong local gamma correlations over 60 seconds in 33 SEEG patients

  We used and preserved its EDF header reader, contact-name parser, table reader, and HTTP retry code. These functions enabled source retrieval and calibration. The new code computes contact covariance and strong-link shares.

• usesSEEG pairs with onset labels had higher mean high-gamma concentration within shafts over sixty seconds in 32 patients

  We use its original EDF header and contact parser. The parser is preserved with attribution.

• usesEight SEEG pairs selected by 70–110 Hz power had excess seizure onset labels in 36 epilepsy patients

  Used the 36-patient cohort, frozen source metadata and object versions, and EDF header/contact parser. Retrieved new ten-second voltage prefixes and included onset shafts to test label frequency in eight power-selected pairs.

• usesA fixed spectral contrast had lower high-gamma pair rank agreement than absolute power across two SEEG records from 36 patients

  This study uses the complete 36-patient cohort, pair rules, EDF header parser, source metadata, and exact source versions. Its archived powers supplied checks for every fresh ten-second extraction. The new analysis also reproduces its absolute-power retention result. This reuse is not independent evidence for that result.

• usesTen-second block limits from 60-second calibration had 44.0% mean coverage for high-gamma log-power means across interictal SEEG records from 36 patients at a 90% target

  The archived native-rate power features, source identities, and voltage audit traces support the new forecast coverage test. All eligible pairs are used.

• usesIndependent contact models with positive gamma variances gave nonzero partial correlations between disjoint channels in complete bipolar chains from 33 SEEG patients

  We use and preserve its EDF header reader, contact-name parser, table reader, and HTTP retry code through the cited input package. These helpers enable the version-pinned source rebuild.

• usesGamma/beta selection gave fewer seizure onset labels than gamma selection for eight SEEG pairs in 36 epilepsy patients

  Original native EDF header parser, preserved as provenance/upstream_extract.py.

• usesMean and median rank disagreement marked greater loss of top-eight high gamma rank across two interictal SEEG records in 36 patients

  The two-record cohort and the earlier power-transfer question informed this test. The present analysis includes seizure onset pairs and tests a flag set from calibration power alone.

• usesAn eight-pair rule increased mean surviving high-gamma power after the worst simulated shaft loss in 36 SEEG test records

  Used all 72 public SEEG feature files and the fixed 36-patient cohort. Preserved its full package, source metadata, digital audit samples, hashes, and voltage retrieval recipe. The new contribution is exact selection for one shaft loss and a separate-record surviving-power test.

• usesSelection by correlation gave more normalized gamma voltage dimensions than selection by power for four SEEG channels in 33 patients

  The fresh-source verification uses the EDF header parser preserved from this publication in provenance/parent/upstream_extract.py. The original code and source attribution are included.

• usesMean and median rank disagreement marked greater loss of top-eight high gamma rank across two interictal SEEG records in 36 patients

  The two-record cohort and the earlier power-transfer question informed this test. The present analysis includes seizure onset pairs and tests a flag set from calibration power alone.
