Clipped inverse pre-pulse power weights increased mean later SEEG forecast error in eight epilepsy patient sessions
This study tested whether pre-pulse voltage power improved a five-pulse SEEG response forecast. It used 886 bipolar readouts at 86 stimulation sites in eight epilepsy patient sessions from public OpenNeuro ds004696 version 1.0.1. The first five good pulses set fixed clipped inverse-power weights. The final five pulses tested the forecast in the 20 to 500 ms window. Compared with an equal mean, the weights increased mean patient error by 2.78 percent. The 95 percent patient bootstrap interval was 1.50 to 4.13 percent. All eight patient contrasts favored the equal mean. The effect was small in readouts selected by early waveform shape. This is a retrospective voltage forecast within sessions. It does not establish useful brain control. The package preserves code, trial products, source hashes, pulse errors, figures, and reproduction instructions.

- usesA fixed voltage gate had higher mean SEEG waveform forecast error than matched random selection in eight epilepsy sessions
Its test of voltage weights before calibration pulses informed the question. The present test uses current target voltage to select later readouts at matched site yield.
- Clipped inverse pre-pulse power weights increased mean forecast error by 2.23 percent for centered 20 to 500 ms SEEG voltage in eight patients with reversed test contact order
[Legacy relation: reproduces] This study supplied the fixed inverse-power rule and clipping bounds. We tested the rule in a second dataset. The error direction agrees. The cohorts, pulse splits, and scoring hierarchies differ.
- Power weights fit from five pulses gave no clear mean 20–500 ms SEEG voltage forecast gain in eight sessions
[Legacy relation: reproduces] The equal-readout calculation reproduced its reported 2.78% error increase for full power weights in the same eight sessions. Its weight rule set the reference comparison.
