Exploring the electrophysiology of Parkinson's disease - magnetoencephalography combined with deep brain recordings from the subthalamic nucleus.

This dataset comprises simultaneous magnetoencephalography (MEG) and subthalamic nucleus (STN) local field potential (LFP) recordings from externalized deep brain stimulation (DBS) patients with Parkinson's disease. Recordings were performed both with and without dopaminergic medication, across resting-state and movement conditions (forearm extension hold and self-paced fist-clenching). The study aims to elucidate the neurophysiology of basal ganglia-cortex loops and how they are modulated by movement and medication status.

wget -xc -i urls.txt

Compute on this dataset

Two routes today, with a third (in-browser one-click submission) landing soon.

  1. NeuroScience Gateway (NSG) portal.

    NSG runs EEGLAB / Brainstorm / MNE pipelines on supercomputing time donated by SDSC. Create an account, point a job at this dataset's S3 prefix (s3://nemar/on004998), and submit.
    nsgportal.org →

  2. 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 on004998
cd on004998 && nemar dataset get
  3. Just the files.

    rclone, aria2c, or any HTTPS client works against data.nemar.org/on004998/ — 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.
