Laboratory Description Researches conducted at the Neuropsychology and Functional Neuroimaging Research Unit [UR2NF - Unité de Recherches en Neuropsychologie et Neuroimagerie Fonctionnelle] are mainly but not exclusively focused on investigating the relationships between sleep and memory consolidation processes, and in a wider perspective centered on the interrelationships between cognitive processes and vigilance states, including sleep and biological rhythms. A specific focus is made on the processes by which novel representations are created in memory and the processes by which novel information is consolidated in long-term memory. We are also interested in the understanding and investigation of major neuropsychological syndromes.
