We evaluated the effect of 2.45 GHz microwave radiation on rats\u2019 fear learning and memory ability to determine the potential risks. The present study aimed to assess the impacts of corticosterone (CORT) levels on the consolidation and reconsolidation of fear conditioning memories. Methods: The rats were evaluated in contextual fear conditioning using foot shocks in both short-term (7 days) exposure and long-term (30 days) exposure. Young male Wistar rats were continually exposed to radio frequency electromagnetic field radiation for 5-6 weeks (1 h\/day) with a frequency, power density, and pulse width of 2.45 GHz, 6.0 mW\/cm2 , and 2 ms, respectively. Several animals housed in identical conditions without exposure to radiation were monitored. Results: Based on the results, a significant increase and decrease in body weight and percentage of the freezing time were observed after the short-term group respectively. However, in the long term, we observed no significant difference in body weight, and the freezing time decreased substantially. Conclusion: As CORT levels were analyzed, long-term radiation might increase stress, which was associated with significant weight loss in rats. <\/jats:p>","DOI":"10.34172\/jlms.2022.52","type":"journal-article","created":{"date-parts":[[2023,1,26]],"date-time":"2023-01-26T10:54:27Z","timestamp":1674730467000},"page":"e52","update-policy":"https:\/\/doi.org\/10.34172\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["The Effect of 2.45 GHz Electromagnetic Fields on Fear Memory Extinction in Male Rats"],"prefix":"10.34172","volume":"13","author":[{"given":"Zobeideh","family":"Dehghani","sequence":"first","affiliation":[{"name":"Department of Bioscience and Biotechnology, Malek Ashtar University of Technology (MUT), Tehran, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5836-8487","authenticated-orcid":true,"given":"Seyed Mohammad","family":"Mahdavi","sequence":"additional","affiliation":[{"name":"Department of Bioscience and Biotechnology, Malek Ashtar University of Technology (MUT), Tehran, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9767-6255","authenticated-orcid":true,"given":"Amir","family":"Modarresi Chahardehi","sequence":"additional","affiliation":[{"name":"Cognitive Neuroscience Research Center, AJA University of Medical Sciences, Tehran, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vahid","family":"Mansouri","sequence":"additional","affiliation":[{"name":"Proteomics Research Center, Faculty of Paramedical Sciences, Shahid Beheshti University of Medical Sciences, Tehran, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Somayeh","family":"Jahani Sherafat","sequence":"additional","affiliation":[{"name":"Laser Application in Medical Sciences Research Center, Shahid Beheshti University of Medical Sciences, Tehran, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"20123","published-online":{"date-parts":[[2022,11,28]]},"container-title":["Journal of Lasers in Medical Sciences"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sbmu.ac.ir\/jlms\/article\/view\/39763\/30097","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sbmu.ac.ir\/jlms\/article\/view\/39763\/30097","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,1,26]],"date-time":"2023-01-26T10:54:28Z","timestamp":1674730468000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sbmu.ac.ir\/jlms\/article\/view\/39763"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2022,11,28]]},"references-count":0,"URL":"https:\/\/doi.org\/10.34172\/jlms.2022.52","relation":{},"ISSN":["2008-9783","2228-6721"],"issn-type":[{"value":"2008-9783","type":"print"},{"value":"2228-6721","type":"electronic"}],"subject":[],"published":{"date-parts":[[2022,11,28]]},"assertion":[{"value":"Shahid Beheshti University of Medical Sciences","name":"journal_owner","label":"Journal Owner"},{"value":"Shahid Beheshti University of Medical Sciences","name":"journal_publisher","label":"Journal Publisher"},{"value":"2022-10-19","order":1,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2022-11-09","order":2,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2022-11-28","order":3,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
