at some doses in some mammalian species (Milton, Randall et al. 1995, Shen, Crabbe et al. 1995, Gonzales, Job et al. 2004, Abrahao, Quadros et al. 2012). However, increased DA could also contribute to the reinforcing effects of ethanol that drive habitual drug seeking and taking (Corbit, Nie et al. 2014). Within the SNc and dorsal striatum there is still much to be understood about the role of ethanol-stimulated DA levels, including the roles in subsequent abuse, and if there is any subregional heterogeneity in this ethanol actions.
