 Very few studies have attempted to directly manipulate activation of brain structures that might be involved in cravings. tDCS allows researchers to selectively activate or inhibit different brain structures that might play a role in craving behaviors. Previous research with manipulating the activation of brain structures found that alcohol cravings decreased among individuals with alcohol dependence who received either left or right anodal stimulation of the dorsolateral prefrontal cortex Boggio et al., 2008. This finding, combined with prior functional neuroanatomical work, and research on the relation of food cravings and nicotine cravings suggesting they share a common biologic mechanism Pepino, Finkbiener, Menella 2009, 2007, suggests that the prefrontal cortex may be a reasonable preliminary tDCS cortical target for potentially inhibiting food cravings.
