Visual Oddball Task (256 channels)

A high-density 256-channel EEG dataset from a visual oddball selective attention task collected in 2004 at the Swartz Center for Computational Neuroscience. The dataset includes anatomical MRI scans with precise electrode localization, enabling source-level analysis. Raw data were acquired using BIOSEMI amplifiers and include detailed event annotations with HED tags for cognitive neuroscience research.

Local processing with nemar-cli.
Pull the dataset to your machine and run any toolbox locally. Honors the published version pinning.
```
npm install -g nemar-cli
nemar dataset clone on002578
cd on002578 && nemar dataset get
```
Just the files.
rclone, aria2c, or any HTTPS client works against data.nemar.org/on002578/ — the manifest carries presigned S3 URLs.

Direct compute access is coming soon. One-click NSG submission from this page is scoped for a follow-up phase. Tracked on nemarOrg/website#6.
