Saturday, April 2; Doelenzaal, University Library, University of Amsterdam, Singel 425 Background: According to the tri-level distinction proposed by David Marr, cognitive neuroscience research distinguishes between the computational task/competence level, the algorithmic level, and the neural implementation level. During this conference, presentations will consider what neuroimaging research tells us about phenomena at these levels and their (cor)relations. In particular, they will consider to what extent the balance or interaction between levels has been changed with the development of brain imaging techniques.
