物质成瘾患者和行为成瘾患者在纹状体和前额叶激活的异同:基于双系统模型的元分析
Dual-system perspectives:A meta-analytic comparison of striatal and prefrontal cortex activation patterns in substance addiction versus behavioral addiction
摘要
Abstract
Based on the dual-system theory of addiction,substance addiction and behavioral addiction result from the interaction between the reflective system,represented by the prefrontal cortex,and the impulsive system,represented by the striatum.While most existing studies separately examined the functional changes in these systems for substance addiction and behavioral addiction,our understanding of their neural mechanisms across different cognitive tasks remains incomplete.Furthermore,the similarities and differences in the neural substrates underlying these two types of addiction have not been fully elucidated.To address these gaps,the present study employed a systematic meta-analytic approach to investigate the neural activation patterns in substance addiction and behavioral addiction during inhibitory control and reward processing tasks.Specifically,the study first conducted a meta-analysis to map the neural correlates of substance addiction and behavioral addiction in these tasks,followed by a contrast analysis to evaluate their similarities and differences in neural activation. The present study used Activation Likelihood Estimation(ALE)to conduct a meta-analysis of neuroimaging data.It included 23 articles on inhibitory control tasks and 30 articles on reward processing tasks for substance addiction.For behavioral addiction,it included 12 articles on inhibitory control tasks and 37 articles on reward processing tasks.The meta-analysis was conducted in standard Montreal Neurological Institute(MNI)space,using GingerALE(3.0.2)to convert Talairach coordinates obtained in the studies to MNI space coordinates.For the inhibitory control tasks,a threshold of p<0.001(uncorrected)was used,with a minimum cluster size of 250mm3.For the reward tasks,the'true'ALE scores were then tested against the ALE scores of the null distribution by adopting a cluster-level family wise error(cFWE)-corrected threshold of p<0.05,while the cluster-forming voxel-wise threshold was set at p<0.001 uncorrected.Finally,contrast analysis was conducted for substance addiction and behavioral addiction under the two different task conditions.The threshold for contrast analysis was set at p<0.01(uncorrected),with a minimum cluster size greater than 50mm³(10,000 permutations). The findings revealed two principal patterns in neural activation:(1)In inhibitory control tasks,there was no overlap in commonly activated brain regions between substance addiction and behavioral addiction.Notably,the dorsolateral prefrontal cortex exhibited decreased activation in substance addiction,while showing increased activation in behavioral addiction.(2)In reward processing tasks,the striatum demonstrated consistently increased activation across both substance addiction and behavioral addiction. In conclusion,the current meta-analysis provides novel insights into the neural mechanisms of substance addiction and behavioral addiction during inhibitory control and reward processing tasks.Both types of addiction are characterized by abnormal activation in the striatum,suggesting a shared impulsive system dysfunction.However,during inhibitory control,substance addiction was associated with reduced activation in the fronto-parietal control network,whereas behavioral addiction exhibited enhanced activation in this network.Additionally,behavioral addiction demonstrated both inhibitory control abnormalities and preserved inhibitory control capacity compared to substance addiction.The study reveals that both substance addiction and behavioral addiction have general abnormalities in the reflective and impulsive systems,but each type of addiction has its own unique neural activation patterns.关键词
