Cell assemblies, coherence in oscillations, and information selection

Our brain is presented with a constant stream of experience: a huge amount of information, too much to be stored in full in our memory. How can we keep only the essential parts of this stream? This is the questions that UvA and CNRS-Coll├Ęge de France have attempted to answer. The hippocampus and the prefrontal [...]

During sleep, memories about our previous experience are replayed, as was previously shown in the hippocampus, in the neocortex and in the striatum. This replay is probably important for memory consolidation, the process of stabilization of memories that is thought to be orchestrated by the hippocampus.
