One of the main aims of EBRA is to facilitate the emergence of research projects in specic areas in active clusters and therefore EBRA supports carefully selected clusters. An EBRA cluster is understood as a research community that can be directed towards basic research, clinical research and/or methodological approaches under a common topic and disease area within brain research. EBRA clusters promote co-operation and exchange between brain research projects and networks. The clusters organise activities with the aim to promote external collaborations, foster the exploitation of results, address data sharing issues and foster access to research infrastructures.
