Larger response energy was linked to greater later variance relative to baseline in 20–500 ms centered bipolar SEEG from eight patients
We tested if response energy from five earlier pulses was linked to variance in five separate later pulses. The public data came from OpenNeuro ds004696 version 1.0.1. The test used 20–500 ms centered bipolar SEEG from eight patients with epilepsy. We compared stimulation sites at the same recording pair. The test retained 84 recording pairs and 882 stimulation-to-readout pairs. Each person had equal weight. The mean Spearman correlation was 0.274, with a 95% person bootstrap interval of 0.181 to 0.369. All eight person estimates were positive. The background predictor had a mean correlation of −0.007. The top response group had a 1.83 times larger later post/pre variance ratio than the bottom group. The package preserves exact trial products, source code, three figures, results, and reproduction steps. Fresh public-source checks passed for patients 05 and 08. Other patients use hash-verified products from prior work. The study does not establish a neural noise mechanism or better brain-computer interface performance.

- A selected response–difference mean rank test passed after spatial mean removal in SEEG and two fMRI cohorts; the primary test failed
Related disjoint-pulse response-size/variance evidence; a different stimulation design and electrical measurement.
- usesA fixed variance mixture gave no clear probability score gain for 4–30 Hz power at 100–500 ms after a pulse in eight SEEG sessions
Its association between response energy and later variance supplied the reason to test variance transfer. We used a different 100–500 ms power target and a new chronological forecast score. The same source cohort is reused. We did not combine its scores with ours or count it as independent evidence.
- usesDistance had an uncertain adjusted link to later variance relative to baseline in 20–500 ms SEEG from eight people
We reused the exact trial Gram matrices, pulse selections, channel tables, and retrieval code. We added source electrode positions and a distance test with site, readout, and early response controls.

This study supplies unchanged pulse products, source metadata, and source-check code. The new analysis tests forecasts of later sample variance.
- usesOffline response noise allocation had an uncertain 20 to 500 ms centered bipolar SEEG forecast gain at three pulses per site in eight recordings
Its association between early response energy and later response variance informed the question. The present study uses noise from two pulses to assign a fixed budget and compares it directly with pre-pulse noise.
- usesTotal 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 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.
