OpenNeuro
OpenNeuro is a collaborative platform bringing together neuroscience datasets from human experiments. It contains MRI (anatomical and functional MRI), EEG and MEG recordings from various scientific studies. The set is structured according to BIDS standards to promote the reproducibility of analyses.
Several terabytes of data, NiFTI (neuroimaging) and BIDS (Brain Imaging Data Structure) formats

Description
The OpenNeuro corpus covers a wide range of brain data:
- Structural MRI, functional MRI (fMRI), DTI (diffusion), etc.
- EEG (electroencephalogram) in the context of rest or cognitive task
- MEG (magnetoencephalogram) for brain dynamics
- Associated behavioral data (reaction time, scores, questionnaires...)
- Harmonized metadata (age, gender, subject groups, possible pathologies)
Datasets are often linked to scientific publications and accessible via browser, CLI, or API.
What is this dataset for?
openNeuro is used to:
- The study of brain connectivity and neural circuits
- Training deep learning models in neuroimaging
- The detection of neurological markers linked to pathologies (Alzheimer's, autism, schizophrenia...)
- The development of BIDS-compliant data analysis tools
- Research in cognitive neuroscience, psychiatry, and neurotechnology
Can it be enriched or improved?
Yes, thanks to:
- Multi-modal alignment between MRI, EEG and behaviors
- The addition of clinical or behavioral labels by secondary annotation
- Operating automated pipelines with tools like FMRIPrep, MNE, Brainstorm, etc.
- Combining with databases like HCP, UK Biobank or NeuroVault

Frequently Asked Questions
Can OpenNeuro be used for functional MRI analysis (fMRI)?
Yes, a large part of the datasets contain fMRI sessions structured according to the BIDS standard, ready to be used with the most common analysis tools.
Is the data anonymized?
Yes. All MRI images are de-identified, with faces blurred and sensitive metadata removed, in accordance with best practices.
Is it possible to contribute to OpenNeuro?
Yes, researchers can submit their own datasets through a supervised process. This promotes open science and replicability.
