The behavioral approach system (BAS) from Gray’s reinforcement sensitivity theory is a neurobehavioral system involved in
the processing of rewarding stimuli that has been related to dopaminergic brain areas. 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 [-]
