Instead of an adaptive outcome, life-threatening experiences may contribute to the development of anxiety disorders and depression. Predator scent stress (PSS) is one of the most utilized rodent models of stress-induced psychopathology, in which rodents are exposed to a volatile predator cue that signifies imminent danger. It is unclear if the duration of a life-threatening experience could have differential consequences on the expression of anxiety-like and depression-like behaviors. For this reason, the goal of this present study was to evaluate the effect of different exposure durations (3 min., 10 min., or 20 min.) to the scent of bobcat urine. Wistar rats housed under 12/12 dark cycle in standard laboratory conditions were exposed to the PSS model and 24 hrs. after the stressor, behavioral consequences were evaluated in the open field test, saccharin preference test, and forced swim test. The results obtained show that a 10-minute exposure is sufficient to induce an anxiety-like and a depression-like behavioral profile. We conclude that the time exposure could be a major variable to obtain clear and trustable results and to avoid overexposure to stressor. 2020 artículo científico 2007-4832 https://www.redalyc.org/articulo.oa?id=358971691002 https://www.redalyc.org/journal/3589/358971691002/ https://www.redalyc.org/journal/3589/358971691002/html/ https://www.redalyc.org/journal/3589/358971691002/358971691002.epub https://www.redalyc.org/journal/3589/358971691002/movil 10.22201/fpsi.20074719e.2020.2.343 en http://www.redalyc.org/revista.oa?id=3589 Acta de Investigación Psicológica - Psychological Research Records application/pdf Universidad Nacional Autónoma de México Acta de Investigación Psicológica - Psychological Research Records (México) Num.2 Vol.10 |
