Mean estimated SEEG site map alignment was 0.28 for 20 to 100 ms and 100 to 500 ms in five sessions under stable means and independent group errors

We tested whether early and late SEEG responses gave the same relations between stimulation sites. We used public OpenNeuro ds004457 version 1.0.2. The fixed cohort had five patient sessions, 183 sites, 15 bipolar recording pairs, and 1464 physical pulses. We compared 20 to 100 ms with 100 to 500 ms. Each site supplied four groups of two pulses. Products from separate groups estimate site-map moments without a model noise term when means are stable and group errors are independent with mean zero. The alignment ratio is biased. The mean estimate was 0.283, with patient values from 0.152 to 0.573. Its descriptive patient bootstrap interval was 0.183 to 0.436. This interval omits pulse-level uncertainty. Planned settings gave means from 0.281 to 0.450. Some individual values changed substantially. We did not test BCI control or a clinical outcome. The package preserves inputs, all maps, three figures, code, proofs, source hashes, and replay checks. All 75 fresh raw files matched their hashes. Fresh extraction gave ten byte-identical input files. Analysis replay with a second NumPy version matched all 34 result files within numerical tolerance.

Used as related method context after the primary calculation. It uses separate products from four pulse groups to estimate response spectrum moments in the same cohort. The current result measures early and late map alignment. No code or result arrays were imported from it.

Used its full preserved voltage bins, event tables, source metadata, fixed cohort selection, and retained pulse membership. The new analysis estimates agreement between early and late site maps. It does not repeat its waveform compression test.

Used its reported early and late site decoding comparison as scientific context. The current calculation measures site-map alignment. No code or predictions were imported. Both reports use the same source patients.

usesPre-pulse ridge updates had lower mean relative forecast error than early updates in five SEEG replays with earlier fits from other shafts
Its extraction work was inherited through the direct data parent. The source bins, extraction code, manifest, and attribution are preserved.
usesMean SEEG forecast gains fell from 14.1 to 5.6 percent when whole shafts were excluded in five sessions
This publication supplied the fixed voltage bins, source metadata, selection code, and raw retrieval recipe. They made the shaft forecast test possible.
usesNeighboring SEEG site responses had estimated shape separation of 0.16 at 20–100 ms in five sessions under stable means and independent group errors
Its use of four separate pulse groups informed the product estimator and the ratio-bias caution. The present study wrote new pair-level collinearity and validation code. It did not reuse the site-map result arrays.
usesWith four pulses per site, late calibration gave higher late SEEG scores in five offline sessions
We used its fixed five-session voltage bins, event tables, source metadata, manifests, and extraction and retrieval code. Its early and late site-map result informed the question. We added a held-out site-choice comparison between response windows. The cohort is reused.
usesEarly and delayed selection gave 42.5% and 45.6% mean delayed SEEG accuracy for eight remote sites per session in five 6 mA sessions
Its comparison of early and late response maps provided context for a direct test of site selection on separate pulses. We read the report before the new signal analysis. No code or result arrays were imported. Both publications use the same source patients; their evidence is not independent.
usesLate SEEG features gave no clear accuracy gain at eight values per pair in five offline sessions
This earlier site map test motivated the question of whether different late maps improve a compact reader.
usesA calibrated late SEEG score gave a 1.02-point mean site accuracy gain with a 95% interval across zero in five sessions
We used its fixed five-session voltage inputs, site and pair selection, source manifest, metadata, and extraction and retrieval code. Its early and late site map result informed the new score combination question.
