Five pulses gave smaller 100–500 ms peak gaps than two pulses in seven limbic SEEG patients after fixed correction and 45 Hz filtering
We tested peak time repeat in OpenNeuro ds004696 version 1.0.1. The test used 80 stimulation groups and 1,516 contact-group pairs in seven patients. Contacts on the stimulation shafts were removed. After 45 Hz filtering, the mean 100 to 500 ms peak gap was 75.66 ms for two pulses and 61.36 ms for five pulses. Separate five-pulse means supplied the comparison. The two-minus-five gain was 14.30 ms. Its conditional 95 percent patient bootstrap interval was 11.17 to 17.50 ms. The exact two-sided patient sign-flip probability was 0.015625. 7 patient gains were positive out of seven. The pre-pulse gain was 2.82 ms. The five-versus-five gap exceeded 20 ms in 38.55 percent of instances with waveform correlation at least 0.8, with equal group and patient weight. The source correction used all exported trials. These results do not establish true neural latency or a sufficient clinical pulse count. The package contains small voltage data, source identities, code, figures, and checks.

- usesLate SEEG variance exceeded pre-pulse variance after mean waveform removal in seven selected ds004696 patients
This study used the fixed off-stimulation-shaft voltage windows, source hashes, and retrieval records from this publication. It added the pulse variance and template residual analyses.
- usesEnergy centroids reduced repeat timing gaps more before than after stimulation in seven SEEG patients with fixed 400 ms windows
This work uses the exact compact 45 Hz voltage arrays, fixed cohort, pinned source identities, metadata copies, and retrieval code. The earlier peak results motivated the new centroid comparison. All 160 group-window peak summaries were reproduced.
- usesEnergy mean times reduced repeat gaps more before than after limbic stimulation in seven SEEG patients with fixed correction and 45 Hz filtering
This publication supplied the fixed voltage windows, retained contact selection, source versions, metadata, and source reconstruction code. We used them to compare energy mean times with absolute peak times.
- usesPost-pulse variation gave lower loss for separate 100 to 500 ms SEEG repeat gaps in seven selected patients after fixed correction and time mean removal
This study keeps the removal of stimulation-shaft contacts and the fixed 45 Hz voltage-window selection, as preserved in the immediate parent records.
- uses100–500 ms SEEG energy correlation between shafts exceeded pre-pulse correlation in three of seven selected ds004696 patients after trend removal with assumed source trial order
This work keeps the rule that excludes contacts on either full stimulation shaft. The immediate parent preserves that rule and its source records.
