The key outcome variable was the phase in which hippocampal activity was observed: study, early delay, late delay, and/or test. During working memory tasks, long-term memory processes can operate during the study phase, early delay phase (due to extended encoding), or test phase. Thus, working memory processes can be isolated from long-term memory processes during only the late delay period. Twenty-six working memory studies that reported hippocampal activity were systematically analyzed. Many experimental protocol and analysis parameters were considered including number of participants, stimulus type(s), number of items during the study phase, delay duration, task during the test phase, behavioral accuracy, relevant fMRI contrast(s), whether the information was novel or familiar, number of phases modeled, and whether activation timecourses were extracted. For studies that were able to identify activity in different phases, familiar information sometimes produced activity during the study phase and/or test phase, but never produced activity during the delay period. When early-delay phase and late-delay phase activity could be distinguished via modeling these phases separately or inspecting activation timecourses, novel information could additionally produce activity during the early delay phase. There was no convincing evidence of hippocampal activity during the late delay period. These results indicate that working memory does not activate the hippocampus and suggest a model of working memory where maintenance of novel information can foster long-term memory encoding.","PeriodicalId":10413,"journal":{"name":"Cognitive Neuroscience","volume":"13 3-4","pages":"182-207"},"PeriodicalIF":2.0,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9741498","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Human lesion studies indicate memories become hippocampus-independent over years, whereas animal studies suggest this process occurs across relatively short intervals, from days to weeks. Human neuroimaging studies suggest that changes in hippocampal and cortical activity and connectivity can be detected over these short intervals, but many of these studies examined only two time periods. We examined memory and fMRI activity for photos of indoor and outdoor scenes across four time periods to examine these neural changes more carefully. Participants (N = 21) studied scenes 1 hour, 1 day, 1 week, or 1 month before scanning. During scanning, participants viewed scenes, made old/new recognition memory judgments, and gave confidence ratings. Memory accuracy, confidence ratings, and response times changed with memory age. Brain activity in a widespread cortical network either increased or decreased with memory age, whereas hippocampal activity was not related to memory age. These findings were almost identical when effects of behavioral changes across time periods were minimized. Functional connectivity of the ventromedial prefrontal cortex with the posterior parietal cortex increased with memory age. By contrast, functional connectivity of the hippocampus with the parahippocampal cortex and fusiform gyrus decreased with memory age. In sum, we detected changes in cortical activity and changes in hippocampal and cortical connectivity with memory age across short intervals. These findings provide support for the predictions of systems consolidation and suggest that these changes begin soon after memories are formed.","PeriodicalId":10413,"journal":{"name":"Cognitive Neuroscience","volume":"13 3-4","pages":"115-133"},"PeriodicalIF":2.0,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9308837/pdf/nihms-1769153.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9732907","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A discussion paper by Tallman, Clark, and Smith (this issue) found that functional connectivity of the hippocampus with the parahippocampal cortex and fusiform gyrus decreased with memory age, providing support for systems consolidation. Commentaries were received by Berdugo-Vega and Gräff (this issue), Feld and Gerchen (this issue), Gellersen and Simons (this issue), Gobbo, Mitchell-Heggs, and Tse (this issue), Gilmore, Audrain, and Martin (this issue), Kirwan (this issue), Manns (this issue), Runyan and Brooks (this issue), Santangelo (this issue), and Yang (this issue). The author response considered the content and context of memorial information along with neuroanatomy and functional specialization and conducted new analyses to clarify their findings. An empirical fMRI paper by Thakral, Yu, and Rugg (this issue) reported that the hippocampus was sensitive to the amount of contextual information retrieved, regardless of remember-know status. Another empirical study by Bjornn, Van, and Kirwan (this issue) found that hippocampal activation changes were correlated with the number of fixations at study for correct but not incorrect mnemonic discrimination judgments. A second discussion paper (Slotnick, this issue) concluded that no fMRI studies have provided evidence that the hippocampus is associated with working memory. Commentaries were received by Courtney (this issue), Kessels and Bergmann (this issue), Peters and Reithler (this issue), Rose and Chao (this issue), Stern and Hasselmo (this issue), and Wood, Clark, and Nee (this issue). The articles in this special issue illustrate that the roles of the hippocampus in long-term memory (and other types of memory) are under active investigation and provide many directions for research in the immediate future.","PeriodicalId":10413,"journal":{"name":"Cognitive Neuroscience","volume":"13 3-4","pages":"113-114"},"PeriodicalIF":2.0,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10415857","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
