How the platform works
From registration to download and AI-assisted analysis, in four steps.
1 · Create your researcher account
Access to searching and downloading the databases is exclusive to registered users. Registration is free: provide your name, email, institution and research area.
2 · Explore the datasets
Use the keyword search (e.g.: epilepsy, working memory, parkinson) and filter by modality — MRI, EEG, iEEG, MEG, PET or fNIRS. Each dataset provides title, authors, number of subjects, tasks, total size, DOI and the full README. The data comes from the public OpenNeuro archive, with more than 1,800 studies validated against the BIDS standard.
3 · Download the data your way
For individual files, the download runs directly in the browser. For the complete dataset, the platform generates ready-to-use commands for:
- AWS S3 — aws s3 sync --no-sign-request (faster, no AWS account needed);
- openneuro-py — official Python client;
- DataLad — full data versioning for reproducible research.
Every download is recorded in your history.
4 · Talk to Dr. Áxon
On any dataset, click "Ask the AI" to open a conversation already contextualized with the selected study. Dr. Áxon acts as a senior neuroscientist, neurosurgeon and leading specialist in neurotechnology and AI: he helps you interpret the experimental design, suggest pipelines (fMRIPrep, MNE-Python, FSL, SPM…), discuss statistics and plan analyses — in Portuguese or in the language you prefer.
Frequently asked questions
Is the data really free?
Yes. The datasets are published on OpenNeuro under the CC0 license (public domain) and may be used in research, teaching and development. We always recommend citing the dataset DOI and the associated publications.
What is the BIDS standard?
The Brain Imaging Data Structure is an international standard for organizing neuroimaging data: consistent file names, folder structure and JSON/TSV metadata, which makes it possible to use automated and reproducible pipelines.
Does the AI replace scientific supervision?
No. Dr. Áxon is a research support tool — excellent for speeding up reviews, discussing methods and writing analysis code — but scientific and clinical decisions remain with qualified researchers and professionals.
