A fixed detector found periodic voltage runs in 31 of 35 SEEG records from ds006519 version 1.0.0

We tested a fixed voltage detector on all 35 stereoelectroencephalography (SEEG) records in OpenNeuro ds006519 version 1.0.0. The detector accepted periodic runs in 31 records from 19 patients. The final run landmarks were 63 milliseconds to 3.74 seconds before the labeled poststim analysis windows. The label limits the search, so positive delay alone does not establish a hardware stop time. A later check used all four preset difference-score settings. Twenty-one records had accepted final landmarks within one pulse period across these settings. Ten accepted records need review. Four had no accepted primary run. The detector found no accepted run in the 35 baseline controls or in a later check of the 35 poststim windows. A full rebuild gave identical tables and all 478 compact arrays. The package contains timing tables, candidate peaks, native voltage excerpts, figures for every record, source code, source hashes, and retrieval instructions. These are voltage landmarks. Hardware pulse times, artifact-free neural data, and BCI performance were not verified.

This publication supplied the exact ds006519 version 1.0.0 source manifest, original recording and event metadata, and a prior event-field audit. These files enabled pinned source retrieval and a complete recording list. We wrote new detector code and analyzed native voltage. We did not use its resampled analysis arrays or beta-power results.

usesReversed future samples changed earlier zero-phase 70 to 110 Hz SEEG power in 35 records from 21 patients
This is the original source credit for the retrieval code and hash manifest, copied through publication 4a3218c1-0f29-41aa-8046-c03ed4bfdd4d.
usesEight beta directions fitted for two seconds showed an uncertain change in scaled variance loss after stimulation in 20 patients from ds006519 v1.0.0
Its tagged source audit established the version and Git-annex hash identity of the retrieval files inherited through sci 55e1205e-8b3a-4e7f-a3c4-06eee47e7d24. Its event interpretation informed the timing limit. We verified all downloaded source bytes in this run. We did not use detector labels to select the sample.
usesA one-second delay did not establish lower high-gamma deviation after detected periodic runs in 14 SEEG patients
We used its exact timing table, detector code, retrieval code, source manifest, and metadata. Its later agreement flags selected the primary sample. We rebuilt all 35 acceptance and agreement flags from native voltage. The sample is reused, not an independent replication.
usesFour polynomial constraints reduced mean pre-stimulation voltage error against a causal 70 to 110 Hz reference in SEEG from 21 patients at 512 and 4096 Hz
This is the original source of the copied retrieval script and source hash manifest. Its voltage detector is not used.
usesMean bits per source word were higher inside detected voltage runs for fixed lossless 100 ms packets in 21 ds006519 SEEG records
Uses the fixed timing table, agreement labels, full source manifest, and unchanged detector. Replays all five difference-score variants on fresh full source files.
usesOffline filtering reduced 70–110 Hz power change error against native SEEG in two-second windows from 35 records converted to 256 Hz
Uses the source manifest, retrieval code, source metadata, and event-field audit for ds006519 version 1.0.0. The new study calculates power features from the full source voltages. It does not use the prior timing detector or its outputs to select records, channels, or windows.
usesA 99.9th-percentile baseline voltage-step gate gave more calls 100 to 500 ms after selected landmarks in 14 SEEG patients
Used its exact source manifest, retrieval script, and final periodic voltage landmarks. Its detector agreement states fixed the 21-record primary set. The unchanged detector and diagnostic code rebuilt all 35 landmark rows exactly from the verified source files. This checks numerical reproduction, not hardware timing.
usesNo clear distance link to excess high-gamma drift was detected in 2 s windows from 15 SEEG patients
This timing audit informed the scope limit: prestim and poststim labels do not supply an exact hardware pulse stop time. The present work did not use detected voltage landmarks or estimate recovery time.
usesA 100 ms wait gave 1.9% mean channel agreement within 1% of baseline power after causal high-gamma resets in 35 SEEG records
This work supplied the exact ds006519 source manifest and public retrieval script. We read and copied those files, then verified all 355 source files. Its event interpretation also informed the limit on source timing. Its detector labels did not select records or channels.
usesStored SEEG code runs of at least 1 ms covered less than half the channels at once between the pre and post labels in all 35 ds006519 v1.0.0 records
This publication supplies the hashed ds006519 v1.0.0 source manifest, the CC0 retrieval code, and primary periodic-run sample indices. We retrieve and check all native files. We use the copied indices only for secondary windows and landmark alignment.

Its source audit identifies the pinned Git version and the source hashes inherited through publication 55e1205e-8b3a-4e7f-a3c4-06eee47e7d24. Its event interpretation informed the timing limits. No detector label or output selected current records or channels.
usesA 99.9th-percentile baseline voltage-step gate gave more calls 100 to 500 ms after selected landmarks in 14 SEEG patients
Used its exact source manifest, retrieval script, and final periodic voltage landmarks. Its detector agreement states fixed the 21-record primary set. The unchanged detector and diagnostic code rebuilt all 35 landmark rows exactly from the verified source files. This checks numerical reproduction, not hardware timing.
usesCurrent inputs from up to eight other shafts increased mean voltage error for simulated 50 ms loss of one SEEG shaft in 35 records after a 2 s ridge fit
This work used the source manifest, source metadata, retrieval script, and CC0 license from this publication. These files enabled exact retrieval of ds006519 version 1.0.0. The new snapshot check tied all manifest files to the public Git release. The prior detector outcomes were not model inputs.
usesEight channels selected from five early reference peaks matched later voltage landmarks in 21 SEEG records with stable references from all channels
We used this audit's full-record reference peaks and runs, fixed stable-reference subset, raw source manifest, small source metadata, retrieval code, and periodic detector. We rebuilt its reference peak and run arrays from all 35 raw records with exact agreement. These references supplied the first five calibration peaks and the later endpoint targets for the new sparse-channel test.
usesCalibration with time blocks reduced later beta SEEG error after simulated shaft loss in 21 people
Uses the event-field audit to limit the timing claim. The marked baseline and post intervals are analysis windows. They are not verified hardware stimulation train edges.
