Here, we identify dissociable components of anxiety, fear, and exploratory drive of sated and foraging mice. With the help of behavioral assays, including the open field task, elevated plus maze, dark\u2013light transition task, and beetle mania task, we demonstrate a general increase in exploration by food restriction. Food-restricted mice bred for high anxiety behavior (HAB) showed ameliorated anxiety- but not fear-related behavior. By means of principal component analysis, we identified three independent components, which resemble the behavioral dimensions proposed by Gray\u2019s Reinforcement Sensitivity Theory (approach behavior, avoidance behavior, and decision making). Taken together, we demonstrate anxiolytic consequences of food restriction in a mouse model of anxiety disorders that can be dissociated from a general increase in foraging behavior.<\/jats:p>","DOI":"10.1038\/s41398-021-01458-9","type":"journal-article","created":{"date-parts":[[2021,5,26]],"date-time":"2021-05-26T05:02:42Z","timestamp":1622005362000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":73,"title":["Exploratory drive, fear, and anxiety are dissociable and independent components in foraging mice"],"prefix":"10.1038","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7103-9621","authenticated-orcid":false,"given":"Daniel E.","family":"Heinz","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3168-7549","authenticated-orcid":false,"given":"Vivian A.","family":"Sch\u00f6ttle","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0323-8079","authenticated-orcid":false,"given":"Paulina","family":"Nemcova","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5480-7780","authenticated-orcid":false,"given":"Florian P.","family":"Binder","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tim","family":"Ebert","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Katharina","family":"Domschke","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2159-5379","authenticated-orcid":false,"given":"Carsten T.","family":"Wotjak","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2021,5,26]]},"reference":[{"key":"1458_CR1","doi-asserted-by":"publisher","first-page":"228","DOI":"10.1016\/j.tics.2019.12.016","volume":"24","author":"D Mobbs","year":"2020","unstructured":"Mobbs, D., Headley, D.
