The final five pulses showed higher mean SEEG alignment after stimulation across eight patients
We tested whether SEEG waveform changes shared a pattern across different recording shafts. The source was OpenNeuro ds004696 version 1.0.1. We used five final good pulses at each of 82 sites in eight patients. The mean alignment score was 0.073 after stimulation and 0.041 before stimulation. The paired increase was 0.032. Its descriptive 95% patient bootstrap interval was 0.006 to 0.066. Seven patients had an increase. Removing each pulse in turn and changing readout weights retained a positive mean increase. With all later pulses, only five patients had an increase and the interval included zero. We provide exact Gram inputs, an exact pulse-label mean identity, three figures, source records, and source retrieval steps. A fresh complete public file for sub-05 reproduced 68 window Gram matrices exactly. This is a descriptive result from a reused clinical cohort. It does not establish sensor prediction, causal brain connectivity, or online brain interface performance.

Its pulse-label control for a single response monitor helped define our question. We tested shared pulse variation in a different dataset with a Gram comparison. We did not use its numerical inputs or treat this study as a replication.

We used its all-pulse Gram inputs, native voltage example, source records, and extraction helpers. We calculated new pulse-pattern scores across different recording shafts. A fresh complete source file for sub-05 checked all 68 window matrices.

Used its waveform alignment result to motivate a check of shared large forecast errors. The present endpoint and recording contact selection differ. Both studies use the same eight source people.
