NEMAR — NeuroElectroMagnetic Data Archive and Tools Resource
Overview
NEMAR is an open-access data, tools, and compute portal for human neuroelectromagnetic data (EEG, MEG, and iEEG), operated by UCSD’s Swartz Center for Computational Neuroscience (Scott Makeig, Arnaud Delorme) in partnership with Stanford University (Russ Poldrack). Funded by NIH BRAIN Initiative since 2019, it functions as a specialised gateway to OpenNeuro for EEG, MEG, and iEEG datasets. Data is not uploaded to NEMAR directly. Any dataset made public on OpenNeuro in those modalities is automatically mirrored to NEMAR within 24 hours via DataLad cloning.
NEMAR adds value over plain OpenNeuro access through automated data quality checks (flat channels, noise levels), visualisations of EEG/MEG signals, and integration with the Neuroscience Gateway (NSG) for cloud-based HPC processing at the San Diego Supercomputer Center, without requiring data download and re-upload.
