A background map with ridge strength 1 increased 20 to 500 ms SEEG forecast error outside a five-pulse response span by 18.6% at 86 selected sites in eight people

This study tested whether voltage before stimulation can forecast response changes outside the shapes from five calibration pulses. The test used OpenNeuro ds004696 version 1.0.1, 86 fixed selected sites in eight people, and 610 later pulses. Each target had 48 voltage means from 20 to 500 ms. Each vector had its time mean removed. A linear map used 15 overlapping before-pulse pairs from the first five trials. The fixed main ridge strength was 1. Mean squared error outside the calibration residual span increased by 18.62%. The descriptive 95% person bootstrap interval was 17.14% to 20.91%. All eight people had more error. Error also increased in the before-pulse test. The result does not establish a limit on all neural state prediction. An exact output span bound and a reusable audit tool support the forecast test. The package preserves voltage inputs, source hashes, saved models, scores, four figures, and the full methods and audit record. GPL analysis and retrieval scripts remain in the local archive and are excluded from the public SCI payload, so exact public replay is unavailable. All eight fresh source checks passed. A full replay matched 1,230 saved arrays and all main score tables exactly.
