Resumen
(ES) La frustración es la reacción de un organismo a una situación en la que recibe una recompensa de
menor magnitud o calidad a la esperada, generando una respuesta emocional negativa manifestada
en su conducta, afecto y estado fisiológico. Se trata de un fenómeno psicológico experimentado
por las personas con bastante frecuencia en su vida diaria, que ha sido estudiado mediante modelos
animales como, por ejemplo, el contraste sucesivo negativo consumatorio (CSNc). En el presente
Trabajo de Fin de Grado (TFG) se utilizó este paradigma experimental con el objetivo de avanzar
en el conocimiento del circuito neurobiológico implicado en la frustración. Con este fin, se
midieron los niveles del marcador de actividad neural c-fos en algunas de las regiones de interés
(ROIs) implicadas en el componente emocional negativo del CSNc: el subnúcleo central la
amígdala (CeA), el núcleo accumbens (NAc) y la habénula lateral (LHb).

To this end, the levels of the neural activity marker c-fos were measured in some of the regions of interest (ROIs) involved in the negative emotional component of the CSNc: the central subnucleus of the amygdala (CeA), the nucleus accumbens (NAc) and the lateral habenula (LHb)
