Increased dopamine availability magnifies nicotine effects on cognitive control: A pilot study

Introduction and objectives: The ability to adapt to new task demands flexibly and to stabilise performance in the presence of distractors is termed cognitive control and is mediated by dopaminergic and cholinergic neurotransmission. We aimed to test the hypothesis that the effect of the cholinergic agonist nicotine on cognitive control depends on baseline dopamine levels. Methods: Thirty-eight healthy non-smokers (16 males; M age =24.05 years)...
