FENS, the Federation of European Neuroscience Societies, represents a large number of national European neuroscience societies and several monodisciplinary societies. FENS was founded in 1998 at the Forum of European Neuroscience in Berlin and is the successor organisation of ENA, the European Neuroscience Association.

FENS was founded with the goal of advancing research and education in neuroscience and representing neuroscience research in the European Commission, IBRO, and other granting bodies. FENS is the European partner of the American Society for Neuroscience.

FENS is governed by the FENS Governing Council. The FENS Governing Council is formed by representatives of all member societies. The Council convenes at least once a year and chooses committee members, officers, the venue of the next meeting, etc. The daily FENS administration is delegated to the Executive Committee, elected by the Council. Members of the Executive Committee are elected for two years, and can be re-elected only once. The Executive Committee is supported by three offices based in Berlin, Bordeaux and Kuopio.
