One component reduced mean 20–500 ms SEEG forecast error in eight STReEF patients with five fit pulses

A stimulation controller needs a small map of the expected voltage response. We tested one component of each early mean map in public STReEF SEEG data (OpenNeuro ds005448, version 1.0.0). Eight patients had 12 fixed conditions each. Five early pulses fitted each map. Five later pulses tested it after the recorded stimulation contact order reversed. No later voltage fitted the model. The mean condition error decrease, averaged equally across patients, was 3.862%. The descriptive 95% patient bootstrap interval was 0.860% to 6.972%. 7 of eight patients had less error. The exact two-sided sign-flip reference was 0.0625. The model used 98.487% fewer numeric values. The before-pulse control had a mean decrease of 10.633%. The early 20–100 ms window had a mean error increase of 11.521%. This is an offline voltage test. It does not establish a neural source or live BCI benefit. The package preserves exact map products, model factors, source hashes, code, and figures.
