Three spread pulse records had higher mean normalized 20–100 ms SEEG forecast error than nearby records at equal mean times in eight patients
Three spread pulse records were compared with three nearby records for SEEG calibration. Nonnegative weights gave both estimates the same mean time. The target was the final-five-record mean. Public OpenNeuro ds004696 data supplied eight patients, 86 stimulation sites, and 886 remote bipolar readouts. In the 20–100 ms window, equal-patient normalized error was 0.756 for spread retention and 0.677 for nearby retention. The mean increase was 11.7 percent. The descriptive 95 percent patient interval for the increase was -0.4 to 24.9 percent. The difference was 0.0791, with interval -0.0023 to 0.1811 and sign-flip value 0.1719. This result does not establish a population effect. The package includes exact pulse products, all weights and row maps, a reusable weight tool, an affine-mean cancellation proof, three figures, and reproduction code. All imported file hashes passed. A fresh complete patient 05 extraction matched every imported array. The matched-duration pre-pulse control was not run. The change was saved before new outcomes. The study tests retained records. It does not test fewer delivered pulses or live BCI benefit.

Uses the inherited GPL extraction functions for contact parsing, broad source region rules, and four window definitions. The new quadratic forecast tool makes no independent-noise interpretation of the descriptive calibration variance.

Uses the complete all-pulse Gram products, chronological row maps, pinned source receipts, and source extraction code. Its early order result motivated this separate, time-matched forecast test. All imported products were hash-checked; a fresh patient 05 extraction matched all arrays.

- Matched SEEG windows gave an uncertain 21 percent after-pulse increase in the spread-to-nearby forecast error ratio in eight patients
[Legacy relation: reproduces] Fresh after-pulse products match this parent for all eight patients. Its nearby and spread mean normalized errors are reproduced to less than 1e-12 absolute error. The new paired outcome uses a different aggregation and does not replace those reported values.
- usesMatched SEEG windows gave an uncertain 21 percent after-pulse increase in the spread-to-nearby forecast error ratio in eight patients
We use the fixed cohort maps, source pins, extraction parser, and time-matched forecast weights from this package. We extract new equal-duration before-pulse products and native samples from all eight full public sources. This fills its stated missing control.
