Resumen
Se llevó a cabo un estudio del papel de la corteza insular (CI) en las preferencias del sabor pareado con consecuencias apetitivas viscerales por administración intragástrica de glucosa. Se llevaron a cabo por un procedimiento de aprendizaje de tipo concurrente, donde se presentaron dos estímulos con diferente sabor al mismo tiempo y mientras uno de los estímulos se emparejo con glucosa, el otro con suero fisiológico. El objetivo de este estudio fue investigar la participación de la CI como la responsable para evocar la adquisición de un aprendizaje apetitivo gustativo (AApG). Los resultaros mostraron que la inactivación de la CI limita la evocación del AApG adquirido y como la glucosa produce los mismos efectos recompensantes que la droga, por tanto, un posible tratamiento para la drogadicción podría ser la inactivación de la CI.
A study of the role of the insular cortex (IC) in paired taste preferences with visceral appetitive consequences by intragastric glucose administration was carried out. They were carried out by a concurrent learning procedure, where two stimuli with different taste were presented at the same time and while one of the stimuli was paired with glucose, the other with physiological saline. The objective of this study was to investigate the participation of IC as responsable for evoking the acquisition of taste appetitive learning (AApG). The results showed that IC inactivation limits the evocation of acquired AApG and that glucose produces the same rewarding effects as the drug, therefore, a posible treatment for drug addiction could be the inactivation of IC
