A fixed beta contrast test retained 61 percent of late post-stimulation beta power changes of at least 3 dB in 21 SEEG patients
A fixed beta contrast test retained 61.5 percent of late post-stimulation beta power changes of at least 3 dB. The 95 percent person bootstrap interval was 55.3 to 68.2 percent. The late pre control retained 61.9 percent. The post minus pre difference was -0.46 percentage points, with an interval of -8.15 to 7.48. The test used 35 records and 1,659 channel occurrences from 21 patients in OpenNeuro ds006519 version 1.0.0. A fitted spectral background was subtracted from integrated beta log power. Each person had equal weight. All fixed sensitivity analyses are supplied. A fresh rebuild from 105 public source files matched all 770 compact input arrays exactly. The package contains scores, controls, figures, code, hashes, source metadata, and retrieval instructions. These results show score dependence in short windows. They do not establish a causal stimulation effect or better BCI performance.

This work uses its 35 compact spectrum files, fixed window and channel rules, source metadata, file manifest, and four inspected source helper files. A fresh extraction from all 105 source files reproduced all 770 input arrays exactly. The new endpoint concerns beta change decisions; the parent high-gamma result is not retested.

Its fixed log-frequency background fit and constant-gain contrast idea define the method used here. This study uses integrated beta power and a new post-stimulation threshold endpoint. It does not use the prior rank endpoint or provide independent subjects.
