A shared gain reduced mean normalized 20–100 ms SEEG forecast error by 0.96 percent in five sessions with four calibration pulses
We tested one gain shared across recording pairs against separate pair gains for later SEEG voltage forecasts. We used OpenNeuro ds004457 version 1.0.2, with 183 sites and 732 test pulses in five sessions from five people. The first four eligible pulses set the gains. The final four supplied separate targets. The main window was 20–100 ms. Each error was divided by its calibration energy. The shared gain gave a 0.96 percent mean error decrease. Three people improved, one worsened, and one with a single pair was unchanged. The empirical person bootstrap range was 0.22 to 1.70 percent. The exact sign-flip reference gave p = 0.25. The before-pulse control gave a larger decrease, 1.44 percent. The 20–500 ms window gave a 0.31 percent decrease. A bound showed that separate fitted gains beat every shared gain on [0, 1] at 28 tested sites, for the fixed means and loss. This is an exploratory test on reused data. It does not establish neural recovery or a BCI benefit. The package preserves five figures, compact inputs, code, source hashes, results, checks, and reproduction instructions. All raw source objects passed hash checks. Fresh extraction and a separate numerical replay matched the archived files.

This publication supplied the separate-pair and shared-site gain method and the earlier comparison on ds004696. We tested the method on ds004457 with four calibration pulses and a 20–100 ms main window. We added a numerically checked common-gain bound for the observed final targets. Different conditions and uncertain person overlap limit cohort replication claims.

This publication supplied 52 checked input, source, and code files: compact ds004457 voltage means and events, fixed read contacts, eligibility rules, BIDS metadata, source hashes, and the retrieval and extraction recipe. We retained those inputs and tested all 183 eligible sites without the parent neighbor-history restriction.

Its short-window shared-gain result helped define the transfer question and fixed window checks. We retain its distinction between shared gains and local response templates.

This publication supplied the compact voltage extract, source metadata, fixed contacts, eligibility rules, source hashes, and raw retrieval and MEF extraction code. We rebuilt and verified the inputs, then tested nested site library sizes.
