Increased theta power at frontal and parietal midline regions is known to contribute to successful navigation. However, the dynamics of cortical theta and its role in spatial learning are not fully understood. This study aimed to investigate theta oscillations via electroencephalogram (EEG) during spatial learning in a virtual water maze. Participants were separated into a learning group (\n                    <jats:italic>n<\/jats:italic>\n                    \u2009=\u200925) who learned the location of a hidden goal across 12 trials, or a time\u2010matched non\u2010learning group (n\u2009=\u200925) who were required to simply navigate the same arena, but without a goal. We compared all trials, at two phases of learning, the trial start and the goal approach. We also compared the first six trials with the last six trials within\u2010groups. The learning group showed reduced low\u2010frequency theta power at the frontal and parietal midline during the start phase and largely reduced theta combined with a short increase at both midlines during the goal\u2010approach phase. These patterns were not found in the non\u2010learning group, who instead displayed extensive increases in low\u2010frequency oscillations at both regions during the trial start and at the parietal midline during goal approach. Our results support the theory that theta plays a crucial role in spatial encoding during exploration, as opposed to sensorimotor integration. We suggest our findings provide evidence for a link between learning and a reduction of theta oscillations in humans.\n                  <\/jats:p>","DOI":"10.1111\/ejn.16185","type":"journal-article","created":{"date-parts":[[2023,11,13]],"date-time":"2023-11-13T23:09:15Z","timestamp":1699916955000},"page":"4341-4356","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":19,"title":["Theta oscillatory power decreases in humans are associated with spatial learning in a virtual water maze task"],"prefix":"10.1111","volume":"58","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5281-0641","authenticated-orcid":false,"given":"Conor","family":"Thornberry","sequence":"first","affiliation":[{"name":"Department of Psychology Maynooth University  Maynooth Ireland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michelle","family":"Caffrey","sequence":"additional","affiliation":[{"name":"Department of Psychology Maynooth University  Maynooth Ireland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sean","family":"Commins","sequence":"additional","affiliation":[{"name":"Department of Psychology Maynooth University  Maynooth Ireland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2023,11,13]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0166-4328(98)00019-9"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0124521"},{"key":"e_1_2_10_4_1","volume-title":"Manual of directions and scoring","author":"Battery A.
