--- res: bibo_abstract: - The hippocampus is thought to initiate systems-wide mnemonic processes through the reactivation of previously acquired spatial and episodic memory traces, which can recruit the entorhinal cortex as a first stage of memory redistribution to other brain areas. 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.@eng bibo_authorlist: - foaf_Person: foaf_givenName: Joseph foaf_name: O'Neill, Joseph foaf_surname: O'Neill foaf_workInfoHomepage: http://www.librecat.org/personId=426376DC-F248-11E8-B48F-1D18A9856A87 - foaf_Person: foaf_givenName: Charlotte foaf_name: Boccara, Charlotte foaf_surname: Boccara foaf_workInfoHomepage: http://www.librecat.org/personId=3FC06552-F248-11E8-B48F-1D18A9856A87 orcid: 0000-0001-7237-5109 - foaf_Person: foaf_givenName: Federico foaf_name: Stella, Federico foaf_surname: Stella foaf_workInfoHomepage: http://www.librecat.org/personId=39AF1E74-F248-11E8-B48F-1D18A9856A87 orcid: 0000-0001-9439-3148 - foaf_Person: foaf_givenName: Philipp foaf_name: Schönenberger, Philipp foaf_surname: Schönenberger foaf_workInfoHomepage: http://www.librecat.org/personId=3B9D816C-F248-11E8-B48F-1D18A9856A87 - foaf_Person: foaf_givenName: Jozsef L foaf_name: Csicsvari, Jozsef L foaf_surname: Csicsvari foaf_workInfoHomepage: http://www.librecat.org/personId=3FA14672-F248-11E8-B48F-1D18A9856A87 orcid: 0000-0002-5193-4036 bibo_doi: 10.1126/science.aag2787 bibo_issue: '6321' bibo_volume: 355 dct_date: 2017^xs_gYear dct_identifier: - UT:000391743700044 dct_isPartOf: - http://id.crossref.org/issn/00368075 dct_language: eng dct_publisher: American Association for the Advancement of Science@ dct_title: Superficial layers of the medial entorhinal cortex replay independently of the hippocampus@ ...
