Fast lateral inhibition mediated by GABAergic interneurons may implement a winner-takes-all mechanism in the hippocampal input layer. However, it is not clear whether the functional connectivity rules of granule cells (GCs) and interneurons in the dentate gyrus are consistent with such a mechanism. Using simultaneous patch-clamp recordings from up to seven GCs and up to four PV+ interneurons in the dentate gyrus, we find that connectivity is structured in space, synapse-specific, and enriched in specific disynaptic motifs. In contrast to the neocortex, lateral inhibition in the dentate gyrus (in which a GC inhibits neighboring GCs via a PV+ interneuron) is ~ 10-times more abundant than recurrent inhibition (in which a GC inhibits itself). Thus, unique connectivity rules may enable the dentate gyrus to perform specific higher-order computations","lang":"eng"}],"publication":"Nature Communications","external_id":{"isi":["000449069700009"]},"quality_controlled":"1","project":[{"grant_number":"692692","name":"Biophysics and circuit function of a giant cortical glumatergic synapse","_id":"25B7EB9E-B435-11E9-9278-68D0E5697425","call_identifier":"H2020"},{"_id":"25C5A090-B435-11E9-9278-68D0E5697425","call_identifier":"FWF","name":"The Wittgenstein Prize","grant_number":"Z00312"}],"date_published":"2018-11-02T00:00:00Z","day":"02","ec_funded":1,"status":"public","publication_status":"published","oa_version":"Published Version","oa":1,"article_type":"original","tmp":{"short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png"},"acknowledgement":"This project received funding from the European Research Council (ERC) under the European Union’s Horizon 2020 research and innovation programme (grant agreement No 692692) and the Fond zur Förderung der Wissenschaftlichen Forschung (Z 312-B27, Wittgenstein award), both to P.J..","isi":1,"intvolume":"         9","file":[{"file_size":4651930,"checksum":"9fe2a63bd95a5067d896c087d07998f3","access_level":"open_access","relation":"main_file","file_id":"5715","file_name":"2018_NatureComm_Espinoza.pdf","date_created":"2018-12-17T15:41:57Z","content_type":"application/pdf","date_updated":"2020-07-14T12:45:28Z","creator":"dernst"}],"has_accepted_license":"1","month":"11","date_updated":"2024-04-25T22:30:30Z","volume":9,"date_created":"2018-12-11T11:44:12Z","department":[{"_id":"PeJo"}],"title":"Parvalbumin+ interneurons obey unique connectivity rules and establish a powerful lateral-inhibition microcircuit in dentate gyrus","_id":"21","author":[{"id":"31FFEE2E-F248-11E8-B48F-1D18A9856A87","first_name":"Claudia ","last_name":"Espinoza Martinez","full_name":"Espinoza Martinez, Claudia ","orcid":"0000-0003-4710-2082"},{"orcid":"0000-0003-2209-5242","full_name":"Guzmán, José","last_name":"Guzmán","first_name":"José","id":"30CC5506-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Xiaomin","id":"423EC9C2-F248-11E8-B48F-1D18A9856A87","last_name":"Zhang","full_name":"Zhang, Xiaomin"},{"id":"353C1B58-F248-11E8-B48F-1D18A9856A87","first_name":"Peter M","full_name":"Jonas, Peter M","last_name":"Jonas","orcid":"0000-0001-5001-4804"}],"ddc":["570"],"type":"journal_article","year":"2018","article_number":"4605"}
