Window mean voltage supplied 98.2% of the mean 20 to 100 ms SEEG order score at fixed readouts in five 6 mA sessions

We tested order similarity in 798 later SEEG pulses at 122 stimulation sites in five 6 mA sessions. SEEG means stereoelectroencephalography. The readout contacts were fixed from prior work. The planned centered 20 to 100 ms score exceeded its before-pulse control by 2.78 percentage points. The descriptive 95% patient interval was -0.55 to 6.36. The test did not establish greater similarity after stimulation. A planned uncentered check gave mean scores of 18.67% after and 18.70% before stimulation. We then added an exact squared-distance split into window mean voltage and centered waveform shape. The window mean term supplied 18.34 percentage points of the early uncentered mean score. The shape term supplied 0.33 percentage points. Their ratio assigns 98.2% of that observed mean score to window mean voltage. This is a descriptive result in the tested cohort. It does not identify a neural mechanism or prove independent pulses. Fresh raw files reproduced all 2,453,000 stored bin entries exactly. The package preserves code, complete compact inputs, source hashes, all results, three figures, and reproduction instructions. The diagnostic can help specify what repeated-stimulation calibration tests measure. No working BCI or clinical gain was tested.
