SCNUED Dataset Description

Dataset Description

SCNUED records low-channel wearable EEG during passive audiovisual emotion induction. EEG signals were acquired with a five-channel portable EEG headband after conductive gel application and signal-quality checks.

No event files are released in v1.0 because the BDF annotation channels do not contain validated nonnumeric event labels.

Quality Notes

Release BDF headers are de-identified by rewriting patient, recording, date, and time fields. EEG data records remain unchanged, and the manifest confirms identical post-header data hashes.

All released BDF files contain the five EEG channels Fp2, O1, O2, C3, and C4 at 250 Hz.
Source filenames are consistent with their source folders in this release.
Participant-level age and sex tables are not released in v1.0; only aggregate demographics are provided.
