Gray’s theory hypothesizes that the functioning of reward brain areas is modulated by BAS-related traits. To test this hypothesis, we performed an fMRI study where participants viewed erotic and neutral pictures, and cues that predicted their appearance. Forty-five heterosexual men completed the Sensitivity to Reward scale (from the Sensitivity to Punishment and Sensitivity to Reward Questionnaire) to measure BAS-related traits. Results showed that Sensitivity to Reward scores correlated positively with brain activity during reactivity to erotic pictures in the left orbitofrontal cortex, left insula, and right ventral striatum. These results demonstrated a relationship between the BAS and reward sensitivity during the processing of erotic stimuli, filling the gap of previous reports that identified the dopaminergic system as a neural substrate for the BAS during the processing of other rewarding stimuli such as money and food. info:eu-repo/grantAgreement/ES/MINECO/CSD2007-00012 info:eu-repo/grantAgreement/ES/MINECO/PSI2010-20168 info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 3.534 2013 MULTIDISCIPLINARY SCIENCES 8 / 56 = 0.143 2013 Q1 T1 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Barrós Loscertales, Alfonso (orcid)0000-0002-8201-0469 Bustamante, Juan Carlos Universidad de Zaragoza Ventura Campos, Noelia Fuentes Claramonte, Paola Rosell Negre, Patricia Ávila Rivera, César 4009 735 Universidad de Zaragoza Departamento de Psicología y Sociología Psicología Evolutiva y de la Educación 8, 6 (2013), e66940 [9 pp] PLoS One PLoS One 1932-6203 3774189 http://zaguan.unizar.es/record/63331/files/texto_completo.pdf Versión publicada 126688 http://zaguan.unizar.es/record/63331/files/texto_completo.jpg?subformat=icon icon Versión publicada oai:zaguan.unizar.es:63331 articulos driver 2017-11-28-13:51:44 ARTICLE
