Participants completed a short-term spatial memory task in virtual space, which required no navigation but involved the recognition of a target location from a foil location based on environmental landmarks. The results showed that spatial memory retrieval based on environmental landmarks was indeed associated with increased signal in regions of the parieto-medial temporal pathway, including the superior parietal cortex, the retrosplenial cortex, and the lingual gyrus. However, the hippocampus demonstrated a signal decrease below the fixation baseline during landmark-based retrieval, whereas there was no signal change from baseline during retrieval based on viewer position. In a discussion of the origins of such negative BOLD response in the hippocampus, we consider both a suppression of default activity and an increase in activity without a corresponding boost in CBF as possible mechanisms.<\/jats:p>","DOI":"10.1162\/jocn_a_00396","type":"journal-article","created":{"date-parts":[[2013,3,26]],"date-time":"2013-03-26T17:07:32Z","timestamp":1364317652000},"page":"1358-1371","update-policy":"http:\/\/dx.doi.org\/10.1162\/mitpressjournals.corrections.policy","source":"Crossref","is-referenced-by-count":9,"title":["Negative BOLD Response in the Hippocampus during Short-term Spatial Memory Retrieval"],"prefix":"10.1162","volume":"25","author":[{"given":"Jonna","family":"Nilsson","sequence":"first","affiliation":[{"name":"1Newcastle University, Newcastle upon Tyne, United Kingdom"},{"name":"2Northumbria University, Newcastle upon Tyne, United Kingdom"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"I.
