Résumé
Sleep participates in memory consolidation. The exploration of the cerebral mechanisms underlying these processes is very important to understand the fascinating human abilities to memorize and the function of this intriguing physiological state that is sleep. Our work provides a better understanding of the cerebral mechanisms conditioning and underlying sleep-dependent procedural motor sequence memory consolidation using behavioral and multimodal neuroimaging approaches (fMRI and MEG). From the synthesis of our multi-approaches studies emerges an unexpected and crucial role of the hippocampus in sleep-dependent procedural memory consolidation as well as an effect of sleep on the restructuration of the cerebral networks leading to motor sequence behavior optimization in the course of consolidation
