NEMAR will act as a portal or gateway to the OpenNeuro data archive. OpenNeuro is a free and open platform that allows researchers to upload and share neuroimaging data. Submitted datasets can then be analyzed by anyone who logs in. OpenNeuro has been designated by the NIMH as a repository for data collected from BRAIN Initiative projects as well as other types of human neuroimaging data; however, to date workflows only exist for fMRI data. This means that even if other types of brain scans were uploaded to OpenNeuro, there is no infrastructure in place for data analysis. NEMAR build the infrastructure and tools necessary to add human neuroelectromagnetic brain imaging to the archive, including EEG (electroencephalography) and its magnetic counterpart, MEG (magnetoencephalography). This brain data will be uploaded through the NEMAR portal at the San Diego Super Computer Center.
