A Polish Electroencephalography, Alzheimer’s Risk-genes, Lifestyle and Neuroimaging (PEARL-Neuro) Database

The PEARL-Neuro Database contains EEG, fMRI, genetic, health, and lifestyle data from 192 healthy middle-aged (50-63) Polish individuals at risk of Alzheimer's disease, based on APOE and PICALM genotypes. A subgroup of 79 participants also underwent neuroimaging (EEG and fMRI) during resting-state and cognitive task protocols (multi-source interference task and Sternberg's memory task), alongside blood test data. The dataset aims to support research on genetic, lifestyle, and neuroimaging correlates of dementia risk in middle-aged adults.

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/on004796), 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 on004796
cd on004796 && nemar dataset get
  3. Just the files.

    rclone, aria2c, or any HTTPS client works against data.nemar.org/on004796/ — 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.
