A fixed bipolar beta test did not detect a mean keypress timing gain across blocks in eight SEEG patients under independent and symmetric null patient gains

We compared fixed cue and keypress time templates for bipolar beta power. The source was OpenNeuro ds004473 version 1.0.2. The test used 511 trials and 819 adjacent contact pairs from eight patients. Five chronological test blocks had a 30-second gap. Both models predicted the same 22 observations per trial. The patient mean keypress gain was 0.0176 percentage points of the constant template error. Its 95 percent patient resample interval was -0.1094 to +0.1373 percentage points. The two-sided sign-flip probability was 0.7266 under independent and symmetric null patient gains. Both mean model errors exceeded the constant template error. The result applies to these fixed models and this sample. It does not establish equal timing or the absence of movement signals. The package preserves new temporal features, source recipes, pins, hashes, code, predictions, figures, resample draws, and separate validation.

usesThe test did not detect a response time beta gain after training site selection in eight SEEG patients under independent symmetric null patient gains
This work supplied the 511-trial, 819-pair common-target features, source metadata, version pins, raw examples, trial rules, and extraction code. We add training site selection, penalty choice, a joint cue and response model, and new independent audits. The same patients are reused.
usesSeparate trial maps did not show a mean beta and high gamma relation within shafts in eight SEEG patients under independent, symmetric null scores
This work supplies the complete 511-trial feature cohort, extraction code, fixed source metadata, and raw range hashes. We rebuilt every feature from the public signals. We use a new spatial map test with separate trial halves.
