SEEG pairs selected for suppression before response showed a mean beta change near zero 0.75 to 1.25 seconds after response in eight recordings
We tested whether pairs selected for beta suppression before a response also show a beta rebound after that response. We used public OpenNeuro ds004473 version 1.0.2. We selected eight pairs per person with 1,332 early trials. We then tested 674 later trials from eight people. At 0.75 to 1.25 seconds after the key response, the mean beta change from rest was 0.005 dB. The descriptive 95 percent person interval was -0.401 to 0.441 dB. Three of eight people had a positive mean change. Beta increased by 1.145 dB from the level before response. A fixed upper rest threshold was crossed by 9.5 percent of the main windows and 7.9 percent of rest windows. This fixed rule gave little mean separation. The result applies to this selection rule, these windows, and this reused cohort. A key response does not measure the end of movement. The package preserves selected voltage samples, figures, code, source versions, hashes, and instructions for repeat analysis.

We used its verified five-window features, retained trial IDs, source metadata, range reader, and power code. These files enabled early pair selection and checks against the same source recordings.

This same-cohort beta study informed the late signal window and the limits of the biological claim. The new study tests timing on the next trial.

This study uses the source feature files, retained trials, metadata, pinned EDF versions, and known suppression result. New late-window features also match its earlier extraction on 674 test trials.
