A five-pulse SEEG test did not show a clear increase in the 4–30 Hz persistence gap after stimulation in eight people

We tested whether power that repeated within five pulses persisted across a later five-pulse group. We used public SEEG data from eight people with epilepsy, with 86 stimulation sites and 886 bipolar readout instances. The main score was within-group power minus across-group power, divided by total power. We compared 100–500 ms after stimulation with a matched before-pulse window. The 4–30 Hz gap changed by 0.19 percentage points. Its descriptive 95% person bootstrap interval was −1.26 to 1.83 points. The exact person sign-flip reference was 0.8516. The main result was uncertain and does not establish equivalence. Across-group low-band power rose above the before-pulse control. Secondary 70–110 Hz estimates varied with the taper and time window. The package preserves three figures, compact data, a proof with explicit error assumptions, source metadata, and numerical replay receipts. All eight complete source files passed full hash checks and reproduced the compact arrays. GPL analysis and extraction code is omitted; the package does not enable a code replay.
