After five calibration pulses, a 100 ms endpoint gave mean later AUC of 0.951 for fixed SEEG pairs in eight sessions

We tested response observation length with public SEEG data from OpenNeuro ds004696 version 1.0.1. Five early pulses chose a recording pair with a 20–500 ms window at each of 86 sites in eight people. The pair stayed fixed. Five early pulses fitted each signed template, and the same five final pulses tested each endpoint. The mean later after-versus-before AUC was 0.951 at the 100 ms endpoint and 0.939 at 500 ms. The full-minus-short difference was −0.0111, with a descriptive 95 percent person bootstrap interval of −0.0312 to 0.0086 and exact sign-flip p = 0.3594. Moving the before control reversed the small mean difference. Eight sites lost AUC at 100 ms. The result does not establish equal performance, a best endpoint, or neural origin. The package preserves source data windows, code, all scores and models, figures, source hashes, and a source retrieval recipe. This is an offline voltage test. It does not measure a live brain-computer interface.

This work supplied the exact candidate products, native single-trial windows, source metadata, and source recipe. We kept its five-pulse pair choices and chronological test split, reproduced its full-window AUC, and tested shorter observation endpoints.

usesPooling three background samples per site gave finite rank thresholds at a 5% target in six of eight SEEG patients
Its earlier endpoint comparison informed the fixed 100 ms primary endpoint. This study reuses the same cohort and supplies no independent patient replication.
usesWindows selected from calibration gave higher mean site accuracy than 500 ms windows in five offline SEEG sessions
Its endpoint question helped define this test. We used another dataset and a site classification measure. We did not combine its patients or scores with our sample.
usesPair selection at 200 to 500 ms did not show a clear SEEG AUC gain with five calibration pulses in eight sessions
Its fixed-pair endpoint test informed the new window question. This study removes early samples and tests a new pair choice under that limit.
usesSix checks gave no clear AUC gain over one 100 ms check in eight SEEG sessions after eight calibration pulses
This publication tested fixed observation endpoints and motivated the 100 ms comparator. Our study tests a running maximum score and uses a different split with three separate threshold controls. We do not claim to reproduce its numerical result.
