This manifests in the amount of episodic content recalled during AM, which may reflect differences in associated functional brain networks. We take an individual differences approach to examine resting-state functional connectivity of temporal lobe regions known to coordinate AM content retrieval with the default network (anterior and posterior hippocampus, temporal pole) and test for associations with AM. Multiecho resting-state functional magnetic resonance imaging (fMRI) and autobiographical interviews were collected for 158 younger and 105 older healthy adults. Interviews were scored for internal (episodic) and external (semantic) details. Age group differences in connectivity profiles revealed that older adults had lower connectivity within anterior hippocampus, posterior hippocampus, and temporal pole but greater connectivity with regions across the default network compared with younger adults. This pattern was positively related to posterior hippocampal volumes in older adults, which were smaller than younger adult volumes. Connectivity associations with AM showed two significant patterns. The first dissociated connectivity related to internal vs. external AM across participants. Internal AM was related to anterior hippocampus and temporal pole connectivity with orbitofrontal cortex and connectivity within posterior hippocampus. External AM was related to temporal pole connectivity with regions across the lateral temporal cortex. In the second pattern, younger adults displayed temporal pole connectivity with regions throughout the default network associated with more detailed AMs overall. Our findings provide evidence for discrete ensembles of brain regions that scale with systematic variation in recollective styles across the healthy adult life span.<\/jats:p>","DOI":"10.1073\/pnas.2203039119","type":"journal-article","created":{"date-parts":[[2022,10,3]],"date-time":"2022-10-03T15:17:41Z","timestamp":1664810261000},"update-policy":"https:\/\/doi.org\/10.1073\/pnas.cm10313","source":"Crossref","is-referenced-by-count":49,"title":["Hippocampus and temporal pole functional connectivity is associated with age and individual differences in autobiographical memory"],"prefix":"10.1073","volume":"119","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8829-364X","authenticated-orcid":false,"given":"Roni","family":"Setton","sequence":"first","affiliation":[{"name":"Department of Psychology, Harvard University, Cambridge, MA, 02138"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1644-1604","authenticated-orcid":false,"given":"Laetitia","family":"Mwilambwe-Tshilobo","sequence":"additional","affiliation":[{"name":"Montreal Neurological Institute, Department of Neurology and Neurosurgery, McGill University, Montreal, QC, H3A 2B4, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Signy","family":"Sheldon","sequence":"additional","affiliation":[{"name":"Department of Psychology, McGill University, Montreal, QC, H3A 1G1, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gary R.","family":"Turner","sequence":"additional","affiliation":[{"name":"Department of Psychology, York University, Toronto, ON, M3J 1P3, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1530-8916","authenticated-orcid":false,"given":"R.
