Binge drinking is a common alcohol consumption pattern in young adults, associated with impairments in cognitive control and salience reactivity. Increased connectivity between reward and salience regions has been reported in binge drinkers, even without meeting criteria for alcohol use disorder (AUD). Early identification of altered neurocognitive mechanisms may inform preventive strategies. The aim of this study was to compare behavioral performance in a dichotic listening task between binge drinkers and healthy controls, and to explore brain activations linked to attentional control in response to alcohol-related auditory stimuli, in order to select regions of interest (ROIs) for examining their relationship with alcohol use levels. Twenty-seven participants were assessed (11 binge drinkers, 16 controls), all with normal psychiatric, auditory, and neuropsychological evaluations. fMRI images were acquired during the task. All participants performed above chance. A repeated-measures ANOVA revealed a main effect of trial type, with shorter reaction times in bottom-up than in top-down trials, without significant group differences. At the neural level, top-down trials elicited greater activation in dorsolateral prefrontal cortex, thalamus, caudate, putamen, and insula. These findings allowed the definition of ROIs for subsequent correlation analyses between alcohol consumption (AUDIT) and brain activation.
