A fixed alpha phase model has negative mean beta prediction skill in paired 56-second SEEG excerpts from 36 patients
We tested a fixed alpha phase model on public SEEG data from OpenNeuro ds004100 version 1.1.3. We fit two coefficients in file 01 and applied them in file 02 for 3,653 bipolar pairs from 36 patients. The mean relative squared error reduction against zero voltage was -1.1085 percent. The 95 percent patient bootstrap interval was -3.2686 to 0.0908 percent. 18 of 36 patient means were positive. The apparent training mean was 0.7989 percent. After large voltage times were removed, the test mean was -0.0517 percent. The model used simultaneous alpha phase to predict beta voltage. Original time separation and partial overlap are unknown. The result does not identify a neural mechanism. The package contains compact signal data, raw examples, code, source hashes, scores, and rebuild instructions.

- usesIndependent contact rotations gave higher mean one-second beta power correlations between bipolar signals that share a contact than Gaussian models in 36 SEEG patients
Its original paired cohort and pinned source selection were inherited through publication 42dafe47-156f-4dc8-af7b-9bd4d36a26c4. They fixed the 36 patients, 72 records, and contact layouts before the new scores.
- usesTheta and high gamma amplitude correlation maps had positive mean agreement with voltage, shaft, and power controls in paired 56-second SEEG excerpts from 35 patients
We used its fixed patient layouts, source metadata, pinned byte ranges, EDF reader, and raw example. We retrieved all 72 prefixes and calculated new amplitude features. We did not reuse its phase model scores.
