on alcohol, found a lateralized differentiation of the ECNs. As resting state amplitude in the left DLPFC correlated with approach behaviors, the authors suggested that the LECN may be involved in maintaining a bias toward seeking and taking drugs, rather than representing a failure of executive control (Krmpotich et al., 2013). Our results, however, would suggest that poor communication between critical nodes within the LECN might, in fact, represent such a failure.
