“网络成瘾症”（IAD）正在迅速成为世界上许多国家普遍存在的心理健康问题。应该研究网络成瘾的神经生物学基础，以揭示潜在的异质性。本研究采用事件相关功能性磁共振成像（fMRI）Stroop任务，探讨了网络成瘾与男性反应抑制的神经相关性。与健康的同龄人相比，网络成瘾组的前扣带皮层和后扣带皮层表现出更大的“Stroop效应”相关活动（pFDR<0.05）。这些结果可能表明，相对于健康对照组，网络成瘾组的反应抑制过程的效率降低。
‘Internet addiction disorder’ (IAD) is rapidly becoming a prevalent mental health concern in many countries around the world. The neurobiological underpinning of internet addiction should be studied to unravel the potential heterogeneity. The present study examines the neural correlates of response inhibition in males with and without IAD using an event-related functional magnetic resonance imaging (fMRI) Stroop task. The IAD group demonstrated greater ‘Stroop effect’-related activity in the anterior and posterior cingulate cortices (pFDR<0.05) compared to their healthy peers. These results may suggest diminished efficiency of response inhibition processes in the IAD group relative to healthy controls.
