Abstract: The disclosed systems relate to generating brain data visualizations based on federated analysis of brain data. In exemplary embodiments, the brain data visualizations are generated using a system comprising a framework. The framework may include a first computing platform that comprises one or more servers. The framework may also include a first application for communicating via a communication network with a second computing platform that is different from the first computing platform. The second computing platform may comprise a database that stores protected medical data including a plurality of data elements that are directly inaccessible individually or directly inaccessible in aggregate by a user of the first computing platform. In one embodiment, the one or more servers of the first computing platform comprise memory storing instructions that are executable by one or more computer processors of the first computing platform to execute the various processing stages outlined in this disclosure.
