One way to model anxiety disorders is through behavioral tests of anxiety, (such as the elevated plus maze and the open field test), and fear (using the fear conditioning paradigm and active avoidance). Furthermore, animal models are relevant to study the involvement of different brain areas, like the amygdala, hippocampus and prefrontal cortex. In general, fear and anxiety can be considered as normal adaptive responses; however, elevated levels of both might generate detrimental consequences for the individual. Los modelos animales de miedo y ansiedad se han utilizado para la comprensión de trastornos de ansiedad en humanos, sin embargo no ha sido fácil diferenciar ambos conceptos a nivel fisiológico y conductual. Una forma de modelar estos trastornos es mediante pruebas conductuales de ansiedad (como el laberinto en cruz elevado o la prueba de campo abierto) y de miedo (como el condicionamiento al miedo y la evitación activa). Además, estos modelos permiten estudiar diferentes áreas cerebrales involucradas como la amígdala, el hipocampo y la corteza prefrontal. En general, el miedo y la ansiedad se pueden considerar respuestas adaptativas normales, sin embargo niveles elevados de ambos pueden generar consecuencias perjudiciales para el individuo. 2015-05-19T16:21:37Z 2015-05-19T16:21:37Z 2014-11-19 11:02:48 2015-05-19T16:21:37Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion http://revistas.ucr.ac.cr/index.php/actualidades/article/view/14595 http://hdl.handle.net/10669/12719 10.15517/ap.v28i117.14595 es Actualidades en Psicología Vol. 28 Núm. 117 2014 1-12 application/pdf text/html
