Fixed SEEG ranges showed no clear increase in excess same-side misses across shafts at 20–500 ms after pulses in eight people

We tested whether fixed SEEG size ranges missed together on different recording shafts. We used public OpenNeuro ds004696 version 1.0.1. The test retained 83 stimulation sites in eight people and five late pulses per site. The excess of same-side misses was 0.66 percentage points in the 20–500 ms window and 0.18 points in the baseline window. The mean paired change was +0.48 points. A descriptive 95% person bootstrap interval was −0.31 to +1.70 points. The exact sign-flip reference value was 0.695. The result does not show a clear increase or establish that the change is zero. Omitting one person changed the mean to −0.08 points. The package adds an exact independent-shaft-order audit that keeps pairs on one shaft together. It preserves code, compact input data, pulse outcomes, fits, scores, three figures, source hashes, and repeat instructions. Fresh full-source extractions for two people matched every archived input field. The other six source checks are inherited. These data do not establish a neural cause or a live brain-computer interface benefit.

    This earlier result supplies scientific context. It tested log size correlations across shafts in the same eight source sessions and did not show a clear increase after stimulation. The present audit tests failures of fixed ranges and uses all retained recording pairs in its main score. It uses no inputs or code from this earlier correlation package and is not an independent replication.

    This study uses all 25 compact input files, the unchanged source extraction code, data instructions, and source provenance from this publication. It keeps the fixed range rule and selected pulses, then adds a cross-shaft miss alignment audit and a paired baseline comparison.

    This version corrects the archive checker so that it excludes the metadata folder added by sci fetch. The first full archive retrieval exposed that problem. The data, analysis code, scores, and figures are unchanged. This version includes the correction and its retrieval check record.
