Enhancement of Brain Circuit of Inhibitory Control in Obese Patients Undergoing Gastric Banding

"tDCS is a well-established, safe and noninvasive neuromodulation technique that is based on the application of a weak direct current to the scalp that flows between two electrodes-anode and cathode. Although there is substantial shunting of current in the scalp, sufficient current penetrates the brain to modify the transmembrane neuronal potential, and thus influence the level of excitability and modulate the firing rate of individual neurons.~In this study, participants will receive 10 daily sessions of tDCS (sham/real) over a period of two weeks."
