Brain-CODE
Overview
Brain-CODE is the large-scale neuroinformatics platform of the Ontario Brain Institute (OBI), developed since 2012 for the collection, curation, federation, sharing, and analysis of multimodal neuroscience data across brain disorders. It serves 240+ researchers at 40+ institutions across Canada, storing data from OBI’s five Integrated Discovery Programs (IDPs) alongside data from other research teams.
Brain-CODE is one of the three primary data platforms integrated into the CONP (Canadian Open Neuroscience Platform) portal, alongside LORIS and XNAT, and has been an early implementor of FAIR Principles in clinical neuroscience since its inception.
Platform Architecture
Brain-CODE is built around five core components:
- Data capture uses standardised web forms with Common Data Elements (CDEs) across OBI’s IDP studies, supporting clinical, neuroimaging, genetic, and behavioural data.
- Data storage provides secure, encrypted storage on Canadian-hosted infrastructure with Privacy-by-Design and participant data de-identified.
- Data integration enables cross-disorder harmonisation through shared CDEs, supporting queries across data modalities and brain disorders.
- Analytics provides a web-based high-performance computing environment with advanced software for data management, curation, and analysis.
- Federation provides bidirectional links to external databases including LORIS at McGill University, XNAT, and the CONP portal.
FAIR Implementation
Brain-CODE was one of the earliest platforms to operationalise FAIR Principles in clinical neuroscience (since 2012), documented in a 2023 paper in Frontiers in Neuroinformatics. Findability is addressed through registration of all data releases on the CONP portal with DATS metadata, DOI assignment, and standardised metadata schemas. Accessibility is enabled via the web portal with a controlled access model and standardised consent language for de-identified data reuse. Interoperability is achieved through Common Data Elements, LORIS and XNAT federation, and DATS metadata compatible with CONP portal indexing. Reusability is supported by standardised consent for secondary research use, a published data governance policy, and documentation included with all data releases.
Data Releases and Open Datasets
Brain-CODE hosts 10+ datasets on the CONP portal. ONDRI (Ontario Neurodegenerative Disease Research Initiative) provides multimodal longitudinal data on Alzheimer’s, Parkinson’s, ALS, vascular and FTD. CHILD-BRIGHT covers brain-based childhood disability including cerebral palsy. POND covers neurodevelopmental disorders including autism, ADHD, OCD, and fragile X. Depression and concussion programme datasets are also available. All datasets are described using a customised DATS (Data Tags Suite) metadata model and accessible via DataLad through the CONP portal.
Privacy and Governance
Brain-CODE implements a Privacy-by-Design architecture throughout. Privacy-Preserving Record Linkage (PPRL) using El Gamal homomorphic encryption enables linking of Brain-CODE records with health administrative data. A Data Access Committee governs external data requests. An Informatics Steering Committee oversees platform direction. The Brain-CODE Governance Policy is publicly available.
