Hippocampal reactivation occurs during sharp wave-ripples, in which synchronous network firing encodes sequences of places.We investigated the coordination of this replay by recording assembly activity simultaneously in the CA1 region of the hippocampus and superficial layers of the medial entorhinal cortex. We found that entorhinal cell assemblies can replay trajectories independently of the hippocampus and sharp wave-ripples. This suggests that the hippocampus is not the sole initiator of spatial and episodic memory trace reactivation. Memory systems involved in these processes may include nonhierarchical, parallel components."}],"oa":1,"department":[{"_id":"JoCs"}],"title":"Superficial layers of the medial entorhinal cortex replay independently of the hippocampus","article_processing_charge":"No","language":[{"iso":"eng"}],"date_created":"2018-12-11T11:50:19Z","publication_identifier":{"issn":["00368075"]},"pubrep_id":"976","file_date_updated":"2018-12-12T10:10:22Z","intvolume":"       355","project":[{"call_identifier":"FP7","_id":"257A4776-B435-11E9-9278-68D0E5697425","grant_number":"281511","name":"Memory-related information processing in neuronal circuits of the hippocampus and entorhinal cortex"}],"day":"13","issue":"6321","page":"184 - 188","citation":{"mla":"O’Neill, Joseph, et al. “Superficial Layers of the Medial Entorhinal Cortex Replay Independently of the Hippocampus.” <i>Science</i>, vol. 355, no. 6321, American Association for the Advancement of Science, 2017, pp. 184–88, doi:<a href=\"https://doi.org/10.1126/science.aag2787\">10.1126/science.aag2787</a>.","ista":"O’Neill J, Boccara CN, Stella F, Schönenberger P, Csicsvari JL. 2017.
