Data generation and its analysis aim at developing a radically new diagnostic and therapeutic device for neurological applications which combines a highly innovative ultrasound component for brain imaging and focused stimulation of brain regions with advanced electrophysiological measurements of neural activity. This document presents the first version of the Data Management Plan (DMP) in the AEGEUS project and provides an analysis of the data management policy applied to datasets generated within the Project. This DMP identifies the main datasets and describes research data management during the project, as well as how and what parts of the datasets will be openly shared, will be made accessible for verification and re-use, will be curated, and preserved. The goal of this DMP is to facilitate effective internal data management and make data FAIR (Findable, Accessible, Interoperable, and Reusable). The DMP is, in fact, a living document and it will be updated and further refined with the project’s progress. It is also important to remark that this DMP reflects the provisions established by the project contracts and complements the planned project exploitation, dissemination and IPR procedures.
