Pre-pulse scaling gave no clear gain over half-size one-pulse forecasts of centered SEEG at 20–500 ms in eight sessions
We tested a centered voltage forecast from one calibration pulse. We used public SEEG data from eight patient sessions, 86 stimulation sites, and 886 bipolar readouts. The rule used activity before the pulse to reduce forecast size. At 20–500 ms, the mean patient error reduction from a fixed half-size forecast was 1.10%. The 95% patient bootstrap interval was -2.17% to +5.35%. Only two patients had lower error. This test did not establish a gain. Error was 19.85% higher than the five-pulse benchmark. Each readout error was divided by first-pulse energy.

We used the exact trial products for all eight sessions, the spatial inclusion rules, and the unmodified source extractor. The five-pulse repeat rule supplied the descriptive benchmark. We tested a new one-pulse rule with a fixed half-size control and first-pulse error weights.

- usesEarlier-site variation lowered error divided by first-pulse energy but raised voltage error versus a fixed half-size SEEG forecast from one pulse at 20–500 ms in eight sessions
This study uses its fixed half-size one-pulse control and first-pulse energy error divisor. It tests earlier-site variation instead of target pre-pulse variation.
- usesA learned time basis did not show lower mean one-pulse SEEG forecast error at 94 new sites in five patient sessions
Used the one-pulse question, the half-size first-pulse control, and first-input energy weights to set this new time-separated site-transfer test. Did not use the prior data or results.
