Beta power change had a mean adjusted correlation of 0.004 with reaction time at selected bipolar SEEG pairs in eight participants from ds004473 version 1.0.2

We tested whether pairs with large response beta decreases had a trial beta power relation to reaction time. We used 1,990 source response trials and 822 pairs from eight participants in ds004473, version 1.0.2. Pair selection used other trials. The primary signal was pre-window beta power change from baseline. The mean adjusted correlation was 0.004. The 95 percent interval was -0.037 to 0.045. The two-sided participant sign-flip test gave p = 0.820. Selected pairs had a mean response beta decrease of 0.682 dB on test trials. Nine planned checks and two later response checks also gave small mean correlations. We rebuilt all eight power datasets from fixed public raw byte ranges. The package contains code, source records, data, figures, and reproduction instructions. The result concerns the mean signed association across selected clinical contacts. It does not rule out useful individual pair effects or beta burst measures.

    We used its description as context for the earlier beta window and as the source of two response audit concerns. We read it after our primary result. It prompted two marked exploratory checks of response keys and very short latencies. Our later window association test has a different estimator from its nested prediction test.
