cognitive processing such as VAN, with the former being task-negative and the latter being task-positive (Raichle, 2015). Herman and colleagues (2019) reported the association between binge drinking and VAN connectivity, and given the role of VAN in bottom-up, stimulus-driven attention control (Vossel et al., 2014), the researchers postulated that binge drinking could negatively affect in attention control. It is important to discuss how resting-state connectivity can be influenced by binge drinking. Acutely, alcohol increases cerebral blood flow, especially in healthy social drinkers (Marxen et al., 2014; Sano et al., 1993; Strang et al., 2015; Tolentino et al., 2011). Acute alcohol administration also decreases cerebral glucose metabolism and increases acetate metabolism (Volkow et al., 2013). Chronically, alcohol seems to influence neurocognitive coupling (Shokri-Kojori et al., 2017). In particular, compared to placebo, acute alcohol administration reduced the association between resting-state connectivity and behavioral data measuring mood, motor and cognitive function, and this effect was moderated by chronic alcohol use (Shokri-Kojori et al., 2017). The current study seems to suggest that long-term binge drinking (in the span of 2 years) influences the synchronous oscillations in neuronal activity measured by resting-state fMRI, particularly the synchrony between the default mode and the executive control (attention)
