Uni- and Supramodal Categorical Representations

The neural routing of information into meaningful categorical representations is an essential prerequisite for multiple cognitive processes. It implies two sequential levels, grouping elements according to given categories and, within categories, identification and discrimination of individual exemples. While localized neural correlates of the former operation have already been identified in many functional neuroimaging studies, there are still few data available that demonstrate coding at the subordinate level of identity representation. Using functional magnetic resonance imaging in healthy human subjects, we…
