Effects of nicotine on electroencephalographic (EEG) and behavioural measures of visual working memory in non-smokers during a dual-task paradigm

► Nicotine increased brain activation under conditions of low task complexity. ► Nicotine slowed RTs at highest cognitive load, possibly due to hyper-dopaminergia. ► Post-nicotine hemispheric shifts in EEG activity suggest behavioural inhibition.
