Fixed gates for low power at 70 to below 110 Hz preceded a mean 2.94 dB rise without task stimulation in nine SEEG rest recordings
We tested a control for brain interfaces that use measured power to choose stimulation times. Nine public SEEG rest recordings supplied 539 bipolar pairs. Each record had 352 separate 0.5 s windows. We fixed each pair's low-power gate at the early 20th percentile in the 70 to below 110 Hz band. At later gate times, the next window rose by 2.94 dB on average. The 95% person bootstrap interval was 2.30 to 3.80 dB. The contrast with all candidate times was 2.95 dB, with an interval of 2.32 to 3.81 dB. All nine person contrasts were positive. No task stimulation was applied. High-power gates were followed by a mean change of -3.15 dB. The low-gate contrast stayed positive with longer gates, delayed outcomes, a refractory rule, and one pair per shaft. The result is a no-stimulation control benchmark for a known selection problem. A rise from a selected low value does not establish a stimulation response. The data do not separate neural changes from measurement noise or artifacts. The package includes features, source metadata, fresh raw audit samples, full source hash checks, code, tables, and three figures.

We used its nine rest feature arrays, fixed source and pair selection, raw verification code, and known gate result. We added a new fixed forward forecast comparison on the same cohort.

We reuse all nine rest feature files, the selected sample, source metadata, and pinned retrieval records. We extend the same-pair power-gate test to separate named shafts and an early-fit forecast. We adapt its source check code with credit.
