Transcranial direct current stimulation (tdcs) modulates implicit attitudes towards food in eating disorders

Background. Neuroimaging studies reported abnormal activation in brain regions related to food and body processing in patients with eating disorders (EDs). Neuromodulation of these regions, as application of transcranial direct current stimulation (tDCS), has been increasingly used in experimental and clinical studies on food-related behaviours. However, the neural mechanisms underlying EDs are still unclear and results on tDCS effects on eating behaviours are controversial.
