文摘

Response inhibition in current, former and never smokers was behaviorally similar, but differed in the neural recruitment of the cerebellum. Despite similar task performance across groups, errors differentially activated regions involved in attention and motor control. Regions other than the IFG and dACC should be considered when investigating response inhibition in addiction, especially in older populations. Discussion emphasizes the role of compensatory processes and promotes a connectivity approach to neural processes in addiction.
