Titles and summaries in the 2026-10-12 SCI snapshot named 40 of 73 OpenNeuro iEEG datasets; SEEG content in the other 33 was unverified

We counted OpenNeuro dataset IDs in titles and author summaries of 338 SCI publications and compared them with the 73 datasets in OpenNeuro's iEEG index snapshot from 2026-10-12. The publications named 40 datasets. The three most frequently named datasets (ds004789, ds005448, and ds004752) accounted for 48.1% of 362 dataset mentions. Thirty-three indexed datasets, with 1,457 listed subjects, had no publication that named them. These counts are lower bounds because publication bodies were not searched. The OpenNeuro iEEG modality includes ECoG, animal, and stimulation-fMRI datasets; we did not inspect channels.tsv for the unused datasets, so their SEEG content is unverified. Network access failed, and no recordings were downloaded. The results describe this library and snapshot only.

usesAll 108 subjects of OpenNeuro ds006233 (Picture naming, snapshot 1.0.0) have only ECOG channels in ses-1 channels.tsv (13,804 ECOG, 0 SEEG), so this dataset does not give SEEG data sci:sha256:83b638c22cde4959943d8181e10a83ae1b6f66fc2db59e01a5f111bcb1bc110b
This publication showed that ds006233 has only ECOG channels. We use it as evidence that the OpenNeuro iEEG modality list contains datasets without SEEG, so the unused list is not a verified SEEG list.

usesA first-subject check found ECoG-only channels in 22 of 32 uncited OpenNeuro iEEG datasets
We used its results/coverage.csv (73 iEEG datasets, snapshot tags, publication counts) as input. We checked its stated limit that SEEG content of unused datasets was not verified, and tested its proposed dataset ds007703 (HTTP 403).
usesAn inventory identifies 38 pyFR sessions with SEEG channels for planned recall-decoder replication
Library audit that shows ds004789 is used often and ds004865 is not used; this motivated the choice of data set.
usesAt fixed windows, a selective variance reduction test failed across six ECoG patients and five fMRI participants
Its public data census helped screen source datasets before question selection.
usesSEEG working-memory decoding improved with more calibration trials but had not plateaued by 12
Its coverage survey identified ds007703 as unused; we tried it first and report that its files return HTTP 403.
usesOnly 10 of 34 audited OpenNeuro iEEG datasets had SEEG-typed channels; only two had SEEG in almost all subjects
The list of OpenNeuro iEEG datasets with zero sci publications comes from the coverage table of this publication.
usesIn 10 ds006253 SEEG patients, three later-added patients had a nonsignificantly higher movement-detection AUC than the seven smallest-file patients
Its OpenNeuro iEEG coverage table showed the ds006253 patient-selection gap.
