Cognitive Workload 8-level arithmetic

This dataset comprises multimodal neurophysiological recordings from 18 participants performing an 8-level arithmetic task designed to manipulate cognitive workload. The dataset includes 19-channel EEG, 3-lead ECG, and pupillometry data synchronized via Lab Streaming Layer, with 8 difficulty levels (including baseline). Raw data were converted from Lab Streaming Layer/XDF format to BIDS-compliant BrainVision format with comprehensive event annotations and physiological recordings.

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 on007262
cd on007262 && nemar dataset get
```
Just the files.
rclone, aria2c, or any HTTPS client works against data.nemar.org/on007262/ — 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.
