Bilateral (left cathodal/ right anodal) transcranial Direct Current Stimulation (tDCS) over
the dorsolateral prefrontal cortex (DLPFC) seems to reduce craving and to increase the time
till smoking the first cigarette after the intervention. The current study explores whether
actual cigarette consumption decreases after repetitive tDCS. Cigarette consumption and
craving will therefore be measured by means of EMA, before (at baseline), during and after
multiple tDCS sessions, and at 3 months follow-up.
To study the working mechanism behind the effects of tDCS, electrophysiological responses
(ERPs) and behavioral measures of cognitive control functioning will be taken into account at
baseline, one day after the last tDCS session and at three months follow up.
We hypothesize that cigarette consumption will decrease after repetitive tDCS, and that this
effect is associated with better cognitive control functioning.
