Means of five pulses had higher 10 ms peak time agreement than single pulses in 140 selected SEEG pairs from eight patient sessions, within a 20–500 ms window
We tested whether an early check of mean response shape and peak time also selected repeatable peak times after single electrical pulses. We used public OpenNeuro ds004696 version 1.0.1. Early checks selected 140 remote bipolar SEEG pairs in eight patients. Separate later pulses supplied the test data. In the 20–500 ms window, the mean of five later pulses agreed with the early peak within 10 ms for 88.4% of pairs, after equal patient weighting. The corresponding agreement for one later pulse was 69.5%. The paired difference was 19.0 percentage points; the descriptive 95% patient bootstrap interval was 8.9 to 32.2 points. All five individual pulses agreed for 41.0% of pairs. The package contains exact single pulse voltage, source hashes, code, tables, and three figures. This is an offline test of a voltage landmark in a selected clinical cohort. It does not measure true neural delay or live interface performance.

We used its fixed cohort tables, source records and download code. Fresh source voltage reproduced its group means. We added individual pulse timing tests on the same early and later pulse rows.

- usesPeaks from five SEEG pulses did not show a clear mean timing error decrease over a shared patient time at 20 to 100 ms in 83 cases from eight people
Its five-pulse versus single-pulse peak agreement result motivated the question of added value beyond a shared patient time. The current study reuses the HAPwave cohort and does not provide an independent cohort replication.
- usesTemplate alignment did not show a clear gain over a local peak in joint timing tests on 37 selected SEEG pairs from eight sessions
We used the frozen 886-pair cohort, exact early means, ten-pulse voltage arrays, and source records. We tested a new timing comparison in the same eight sessions.
- usesA fixed shape gate did not establish higher 10 ms peak agreement in 140 selected SEEG pairs
We used its exact voltage arrays, pulse roles, and selected cohort. We reproduced its single-pulse baseline and tested a fixed gate on each later pulse.
