Total power selection from five pulses gave greater later variance gain than variance selection at 2 to 30 Hz and 100 to 500 ms in eight STReEF SEEG patients
We tested recording pair selection after brain stimulation in public STReEF SEEG data. The sample had eight patients, 96 conditions, and 6803 pair instances. Five pulses in block A supplied calibration scores. Five later pulses at reversed contact order supplied test scores. The target was the gain in sample pulse variance relative to the before window. Each rule selected the top quarter of eligible pairs. In the 100 to 500 ms Hann window at 2 to 30 Hz, variance selection had a mean advantage of 0.372 dB over uniform random selection. The descriptive 95% patient bootstrap interval was 0.041 to 0.797 dB. Six of eight patient advantages were positive. The fixed total power rule gave a greater advantage of 0.633 dB. The paired total-minus-variance difference was 0.262 dB, with interval 0.138 to 0.406 dB. All eight differences favored total power. This comparison was a fixed secondary endpoint. The difference was only 0.003 dB in the 300 to 500 ms check. The study extends prior work on the same cohort. Time and contact order are confounded. The result does not establish neural specificity or online BCI performance. All 960 public source ranges matched pinned hashes, versions, and ETags. All 768 rebuilt arrays matched the inputs exactly. The package preserves code, compact data, source records, tables, figures, and replay instructions.

We found this study after our analysis. It gives context for the relation between earlier response energy and later pulse variance. It compares stimulation sites in a different dataset and did not set our local plan.
