In rodent models, VR\u2010based paradigms have elucidated how hippocampal subregions including CA1, CA3, and the dentate gyrus support spatial representation, pattern separation, and memory consolidation. Within VR environments, place cells, grid cells, head\u2010direction cells, and boundary vector cells exhibit characteristic remapping dynamics, reflecting both the experimental advantages and sensory constraints inherent to VR. Although VR enhances reproducibility and integrates seamlessly with advanced methodologies such as two\u2010photon calcium imaging and optogenetics, reduced vestibular and multisensory inputs can limit the fidelity of spatial coding. This review synthesizes current evidence on hippocampal\u2013retrosplenial interactions, synaptic plasticity, and multisensory integration in VR, highlighting mechanistic insights into spatial cognition.<\/jats:p>","DOI":"10.1111\/ejn.70715","type":"journal-article","created":{"date-parts":[[2026,10,14]],"date-time":"2026-10-14T08:54:25Z","timestamp":1791968065000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Exploring Hippocampal Neural Network Dynamics in Rodents Using Virtual Reality: A Narrative Review on Systems, Spatial Coding, and Applications"],"prefix":"10.1111","volume":"64","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7016-2334","authenticated-orcid":false,"given":"Neriman","family":"Ezgin","sequence":"first","affiliation":[{"name":"Institute of Medical Physiology \u201cRichard Burian\u201d Faculty of Medicine, University of Belgrade  Belgrade Serbia"},{"name":"Department of Biotechnology, Institute of Natural and Applied Sciences Cukurova University  Adana Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fatma","family":"Kurul","sequence":"additional","affiliation":[{"name":"Izmir Biomedicine and Genome Center  Izmir Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0788-8108","authenticated-orcid":false,"given":"Arif Engin","family":"Cetin","sequence":"additional","affiliation":[{"name":"Izmir Biomedicine and Genome Center  Izmir Turkey"},{"name":"Department of Biophysics, Faculty of Medicine Dokuz Eylul University  Izmir Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0806-444X","authenticated-orcid":false,"given":"Dragan","family":"Hrn\u010di\u0107","sequence":"additional","affiliation":[{"name":"Institute of Medical Physiology \u201cRichard Burian\u201d Faculty of Medicine, University of Belgrade  Belgrade Serbia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,10,14]]},"reference":[{"key":"e_1_2_14_2_1","doi-asserted-by":"publisher","DOI":"10.1038\/nn.3884"},{"key":"e_1_2_14_3_1","doi-asserted-by":"publisher","DOI":"10.1038\/ncomms10300"},{"key":"e_1_2_14_4_1","doi-asserted-by":"publisher","DOI":"10.1002\/hipo.20810"},{"key":"e_1_2_14_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.neuron.2014.08.042"},{"key":"e_1_2_14_6_1","doi-asserted-by":"publisher","DOI":"10.7554\/eLife.47611"},{"key":"e_1_2_14_7_1","doi-asserted-by":"publisher","DOI":"10.3389\/fncom.2018.00027"},{"key":"e_1_2_14_8_1","doi-asserted-by":"publisher","DOI":"10.1515\/REVNEURO.2006.17.1-2.71"},{"key":"e_1_2_14_9_1","doi-asserted-by":"publisher","DOI":"10.1038\/nn.4062"},{"key":"e_1_2_14_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.neuron.2014.02.014"},{"key":"e_1_2_14_11_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.celrep.2019.11.057"},{"key":"e_1_2_14_12_1","doi-asserted-by":"publisher","DOI":"10.1002\/hipo.450010207"},{"key":"e_1_2_14_13_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.neuron.2023.09.013"},{"key":"e_1_2_14_14_1","doi-asserted-by":"publisher","DOI":"10.3389\/fnins.2021.758388"},{"key":"e_1_2_14_15_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41593-018-0189-y"},{"key":"e_1_2_14_16_1","doi-asserted-by":"publisher","DOI":"10.1038\/lsa.2014.3"},{"key":"e_1_2_14_17_1","doi-asserted-by":"publisher","DOI":"10.1021\/acsphotonics.9b01076"},{"key":"e_1_2_14_18_1","doi-asserted-by":"publisher","DOI":"10.7554\/eLife.34789"},{"key":"e_1_2_14_19_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41467-019-08550-1"},{"key":"e_1_2_14_20_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41586-025-09245-y"},{"key":"e_1_2_14_21_1","unstructured":"Cueva C.
