Laplacian SEEG power from 80 to below 115 Hz separated seizure-onset labels within inferred shafts in 31 patients

Higher local Laplacian SEEG power from 80 Hz to below 115 Hz agreed with seizure-onset labels within inferred shafts in 31 selected patients. The source was public OpenNeuro ds004100, snapshot 1.1.3. Each patient had two fixed 60-second interictal records. The primary median patient AUC was 0.829, with a 95% patient bootstrap interval of 0.780 to 0.875. There were 1041 opposite-label pairs on 78 inferred shafts. Pooling exactly the same contacts gave a median AUC of 0.808. The median paired change was 0.000, with an interval of -0.0006 to 0.0208. This test does not show a clear gain from shaft matching. The package preserves the fixed plan, code, original metadata, window power, results, and retrieval locks. All 68 retained source segments were checked against immutable raw bytes. This result describes agreement with clinical labels. It requires the contact-name shaft assumption and does not test surgical benefit or external prediction.
