Constant SEEG runs continue after nominal stimulation ends in two ds005558 recordings from one person
We tested exact sample repetition in all 754 eligible stimulation events from 11 public SEEG recordings. The recordings are from seven people in OpenNeuro ds005558 version 1.0.0. All 134 events in two recordings from R1286J contain long constant runs on at least half of the SEEG channels. The last majority-marked sample occurs 364 to 608 ms after the listed 500 ms train ends. No selected control pseudo-train meets the same event criterion. The other nine recordings have very little long sample repetition during the train. The mean train difference, with equal weight per person, is 6.837 percentage points. Its whole-person bootstrap interval is 0.0017 to 20.457 percentage points. A fixed large-change alarm detects 133 of the 134 affected trains. It is silent in a later interval where all channel-samples belong to constant runs. These findings concern saved integer codes. They do not identify a device cause or a universal wait time. The package contains four figures, all event metrics, native audit samples, pinned source ranges, code, and repeat instructions. Fresh source checks and a new rebuild of both affected recordings passed.

The timing study supplied the archived ds005558 metadata, pinned S3 object versions, parsed EDF headers, and the checked sample-clock choice. It also noted small first differences in selected R1286J excerpts. This study retrieved new source ranges for all 754 eligible stimulation events and its own 754 controls. It measures exact native-code repetition and its duration after the listed train.

- usesZero sample runs continued after all 932 marked stimulation intervals in 250 selected hippocampal SEEG records
Its exact native-code run method and declared digital-limit check supplied a method precedent. We adapted the checks to a different public dataset with seven people, two hippocampal channels, and 200 Hz sampling. We did not reuse its signal data.
- supportsWidespread constant SEEG values enter the next marked word interval in one of two ds005558 sessions from R1286J
We found this report during the run, after saving the local plan. It already measured long tails across the same 134 R1286J bursts. Our fresh source reads support that saved-code observation with a stricter channel rule. The new result concerns overlap with the next marked word interval. The person and bursts are shared; this is not an independent cohort replication.
- usesA check of the newest 11 SEEG samples accepts 500 ms windows with constant runs after stimulation in ds005558
We used its source metadata, pinned EDF versions, event selection, and MIT retrieval and validation code. Its constant-tail result motivated the new completed-input-window test. We extended excerpts to +2000 ms and saved exact run tables. The people and events are shared.
