How neural circuits acquire relevant information during observation to guide subsequent behavior is unknown. Utilizing an observational spatial working memory task, we show that neurons in the rat anterior cingulate cortex (ACC) associated with spatial trajectories during self-running in a maze are reactivated when observing another rat running the same maze. The observation-induced ACC activities are reduced in error trials and are correlated with activities of hippocampal place cells representing the same trajectories. The ACC activities during observation also predict subsequent hippocampal place cell activities during sharp-wave ripples and spatial contents of hippocampal replay prior to self-running. The results support that ACC neurons involved in decisions during self-running are reactivated during observation and interact with hippocampal replay to guide subsequent spatial navigation.<\/jats:p>","DOI":"10.1101\/2024.03.31.587484","type":"posted-content","created":{"date-parts":[[2024,4,1]],"date-time":"2024-04-01T23:25:37Z","timestamp":1712013937000},"source":"Crossref","is-referenced-by-count":0,"title":["Observational activation of anterior cingulate cortical neurons coordinates hippocampal replay in social learning"],"prefix":"10.64898","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8579-7316","authenticated-orcid":false,"given":"Xiang","family":"Mou","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4115-5888","authenticated-orcid":false,"given":"Daoyun","family":"Ji","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"54368","reference":[{"key":"2025081302050688000_2024.03.31.587484v2.1","doi-asserted-by":"publisher","DOI":"10.1016\/j.cell.2018.04.004"},{"key":"2025081302050688000_2024.03.31.587484v2.2","unstructured":"Bandura, A .
