In this paper, the effect of cathodal transcranial direct current stimulation (ctDCS) of medial frontal cortex was studied. With the method of electroencephalography (EEG) the event-related potentials (ERP) associated with feedback (FRN) and attention allocation (P300) were studied. In addition, the influence of monetary context in the monetary incentive delay task was investigated . There was a significant difference found in FRN between groups of subjects who received cathodal and sham stimulation: the FRN increased in the cathodal group in respect to the control conditions, and the FRN was more sensitive to the monetary context of the game - as was shown for the first time.
