A scale fitted from six pulses reduced later bipolar voltage error against the full mean at four SEEG sites
We tested whether a scale fitted from early pulse variation could reduce later SEEG voltage error. We used OpenNeuro ds004977 version 1.2.0. Four complete sites in four people supplied 593 adjacent bipolar pairs. The first six 6 mA pulses fitted a mean and its scale. The last six pulses tested it. For centered voltage from 20 to 300 ms after a pulse, the geometric error ratio was 0.886 against the full mean and 0.954 against zero. People had equal weight. All four sites favored scaling against the full mean. Three favored it against zero. The separately fitted before-pulse control still had more error than zero. Both primary Holm p values were 0.25. The sample does not establish a population effect or brain signal recovery. We preserve code, fitted means, sufficient waveform products, native examples, tables, figures, source hashes, and instructions. A fresh native rebuild matched all inherited data bytes. A fresh analysis replay matched all five numerical output files.

We used its Gram products, native examples, source metadata, run choices, inclusion rules, and retrieval code. We rebuilt the inputs from native source files and verified exact bytes. The new test compares a scale fitted from early pulses with full and zero forecasts on later pulses. It uses the same four people and sites.

We used its fixed variance scale rule. The new test used five fit pulses in OpenNeuro ds004696 and a 20 to 500 ms window. It extends the earlier six-pulse test in ds004977.
