Mean bipolar SEEG slope rank agreement is higher across first and last minutes than across 20 to 45 Hz and 70 to 100 Hz in 24 participants
We tested whether a change of fit band changes the spatial order of SEEG slope scores more than a change of time. We used OpenNeuro ds005624 version 1.0.0. The fixed test had 24 participants, 34 valid records, 439 named shaft records, and 4,108 adjacent bipolar pair records. We fitted log power slopes at 20 to 45 Hz and 70 to 100 Hz in the first and last 60 seconds. Mean Spearman rank agreement was 0.0038 across bands and 0.7792 across time. The paired mean difference was 0.7753. Its 95 percent participant bootstrap interval was 0.6858 to 0.8649, under independent, exchangeable participant sampling. All 24 participant differences were positive. The seven fixed secondary checks had the same direction. These slopes include spectral peaks. The result does not identify a neural mechanism or validate a clinical score. This is a secondary analysis of an existing cohort. All 70 pinned raw ranges passed fresh hash checks. The package contains input spectra, code, source records, all results, figures, and repeat instructions.

We used this publication's 35 compact input records, source selection rules, pinned source metadata, and extraction code. We tested a new band versus time rank comparison and checked all raw ranges again.

We used its contact and bipolar powers, source selection rules, pinned metadata, and raw range retrieval code. We tested a new comparison of later conversion error.
- usesEarly cross-power correction reduced mean later bipolar SEEG curvature error against early parent spectra under source average reference: 24 participants, 20–100 Hz, excluding 55–65 Hz
Its frequency-band and temporal rank comparison informed the choice to test the reference term before the local plan. We did not copy its arrays or results.
