Time concentration of 80–150 Hz SEEG power gave a mean AUC of 0.706 for seizure-onset labels in 34 patients with two 60 s clips each

This study tested time concentration of power in public SEEG clips. The source was OpenNeuro ds004100, version 1.1.3. Each of 34 patients supplied two 60 s interictal clips. Power used 80 to 150 Hz, with 118 to 122 Hz omitted. Concentration was the share of summed power in the six largest of 60 one-second windows. Bipolar pairs had matching source seizure-onset labels at both contacts. The mean within-patient concentration AUC was 0.706 (95% patient bootstrap interval 0.655 to 0.757). Thirty patients had AUC above 0.5; the exact two-sided sign test gave p = 0.00000616. This sign test assumes independent patients and equal sign probability under its null. Removal of the six largest windows changed power AUC by 0.0095 on average in absolute value. Mean power AUC was 0.734 before removal and 0.730 after removal. The planned high-band checks gave similar estimates. Beta power also had a concentration association, so this result is not unique to the high band. No model was trained. The results measure source label association in the selected clips. The package preserves window data, source versions and hashes, code, figures, a fixed local plan, and reproduction commands. Numerical controls, an independent EDF read, fresh source metadata checks, and an exact offline statistical rebuild passed.

    We reused pinned source identities, metadata, EDF decoding code, and contact and pair rules. These enabled exact retrieval of the same public clips. The new analysis measured 80 to 150 Hz time concentration and upper-window deletion. Previous power outcomes were not analysis inputs.

    The analysis used two selected 60 s interictal clips per patient from OpenNeuro ds004100 version 1.1.3; source labels and pinned source ranges came from this dataset.
