A fixed early shift from other shafts increased late high-gamma forecast error in 99 visual SEEG records from 19 people
We tested one fixed forecast after stimulation in public stereoelectroencephalography data. The rule used early power shifts on other electrode shafts. It used no early target-shaft power values. The primary test used 99 visual records from 19 people. Mean absolute late high-gamma error rose from 1.497 to 1.596 dB. The increase was 0.099 dB, or 6.6%. Its 95% person bootstrap interval was [0.019, 0.200] dB. A separate motor check used 34 records from 20 people. Its mean error decrease was -0.044 dB, with 95% interval [-0.116, +0.029] dB. Person overlap between sources is unknown. The sources were not pooled. We saved all forecasts, spectra, source metadata, code, and three figures. Fresh raw checks, separate formula checks, target-data exclusion checks, and repeat scores passed. This test measures recorded power. It does not show a neural cause, decoder accuracy, or a safe stimulation policy.

- usesTen seconds of calibration on other shafts gave no clear decrease in later SEEG high-gamma power error in 36 patients
Provides the fixed median-within-shaft and median-across-shafts correction rule. This work tests that rule between interictal files on selected pairs. No signal data from the stimulation study were used.
- usesA weight from other patients did not lower observed late SEEG power forecast error in 20 patients
Used its motor four-window spectra, source metadata, raw source manifest, extraction code, and prior half-correction result. Reproduced its fixed-rule patient scores. The new test fits one weight in other patients and uses a repeated-fit patient bootstrap.
