eBRAIN-Health brings a variety of information together. This information includes brain imaging studies such as PET, EEG and MRI, behavioral studies and lifestyle surveys, as well as clinical data from thousands of patients and healthy controls. The data is combined with biological information from knowledge databases and made available for research purposes. The resulting digital twins of the brain will allow a large number of researchers to conduct innovative research within a powerful digital platform. The project involves 20 partners and takes place in cooperation with EBRAINS, the coordinating body of the EU flagship Human Brain Project.
