En su extensión encontraremos un repaso sobre el papel de la emoción en el funcionamiento cotidiano, un modelo de la emoción, así como el abordaje experimental de sus alteraciones relacionadas con la respuesta a estímulos no relacionados con el consumo y el reconocimiento emocional. El objetivo de dicha tarea es activar el interés por un fenómeno poco estudiado pero de gran relevancia como es la emoción en el correcto funcionamiento social y personal y su implicación en el desarrollo de la adicción. Así, los resultados de tales investigaciones se encaminan hacia una hipótesis de rigidez emocional en los sujetos adictos que compromete la respuesta frente los estímulos cotidianos. Palabras clave: adicción, emoción, alteraciones emocionales. This article presents a review of the study of emotion in addictive behaviors, mainly describing alterations in addiction, its role in the evaluation of emotions and the addictive phenomenon. In its course, an overview of the role of emotion in everyday functioning is presented, as well as a model on emotion and the experimental approach related to their response to non-consumption and emotional disturbances recognition stimuli. The goal of this task, is to potentiate a deeper study about emotion in social and personal functioning and its involvement in the development of addiction, taking into account that has been poorly studied but it is a quite relevant aspect in the addiction process. Thus, the results of such research are moving towards a hypothesis of emotional rigidity response in addicted subjects that compromises everyday stimuli.

Research paper thumbnail of Exposure to a Highly Caloric Palatable Diet During Pregestational and Gestational Periods Affects Hypothalamic and Hippocampal Endocannabinoid Levels at Birth and Induces Adiposity and Anxiety-Like Behaviors in Male Rat Offspring

The contribution of the endocannabinoid system to these long-term adaptive responses is unknown. In the present study, we investigated the impact of female rat exposure to a hypercalorichypoproteic palatable diet during pre-gestational, gestational and lactational periods on the development of male offspring. In addition, the hypothalamic and hippocampal endocannabinoid contents at birth and the behavioral performance in adulthood were investigated. Exposure to a palatable diet resulted in low weight offspring who exhibited low hypothalamic contents of arachidonic acid and the two major endocannabinoids (anandamide and 2-arachidonoylglycerol) at birth. Palmitoylethanolamide, but not oleoylethanolamide, also decreased. Additionally, pups from palatable diet-fed dams displayed lower levels of anandamide and palmitoylethanolamide in the hippocampus. The low-weight male offspring, born from palatable diet exposed mothers, gained less weight during lactation and although they recovered weight during the post-weaning period, they developed abdominal adiposity in adulthood. These animals exhibited anxiety-like behavior in the elevated plus-maze and open field test and a low preference for a chocolate diet in a food preference test, indicating that maternal exposure to a hypercaloric diet induces long-term behavioral alterations in male offspring. These results suggest that maternal diet alterations in the function of the endogenous cannabinoid system can mediate the observed phenotype of the offspring, since both hypothalamic and hippocampal endocannabinoids regulate feeding, metabolic adaptions to caloric diets, learning, memory, and emotions.
