Brief Summary:
Psychological disorders characterized by impulsivity often show alterations in dorsal anterior cingulate cortex (dACC) activity. Recent research has therefore focused on non-invasive neurostimulation therapies for the modulation of functional activity in the dACC. To date there has only been one proof-of-concept study providing evidence for modulating dACC activity with non-invasive electrical neurostimulation (e.g. transcranial electrical stimulation). Since transcranial Direct Current Stimulation (tDCS) is relatively safe, tolerable, and mobile as compared to other neurostimulation techniques, it is worthwhile looking further into the effects of tDCS on functional dACC activity. The aim of the present research is to explore whether HD-tDCS can induce changes in the dACC in individuals with high trait impulsivity (N=20) in a double-blind cross-over study. Functional changes in dACC activity will be measured by the error related negativity (ERN), which is an event related potential generated by the dACC. The ERN is less pronounced in people that score high on impulsivity. It is therefore expect enhanced ERN amplitudes after HD-tDCS over the dACC. In addition, performance on the multisource interference task will be used as measure of dACC activity. It is hypothesize that increased dACC activity will be related to decreased impulsivity in high impulsive individuals as shown by improved inhibitory control on the Go/NoGo task. The results of the study may have implications for patient populations that are characterized by impulsivity.
