'Internet addiction disorder' (IAD) is rapidly becoming a prevalent mental health concern in many countries around the world. The neurobiological underpinnings of internet addiction should be studied to unravel the potential heterogeneity in the disorder. 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 significantly greater 'Stroop effect'-related activity in the anterior and posterior cingulate cortices compared with their healthy peers. These results may suggest diminished efficiency of response-inhibition processes in the IAD group relative to healthy controls.
“网络成瘾障碍”(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,以揭示该障碍的潜在异质性。本研究使用事件相关功能磁共振成像(fMRI)Stroop 任务,检查了有无 IAD 的男性的反应抑制的神经相关性。与健康同龄人相比,IAD 组在前扣带和后扣带皮层中表现出显著更大的“Stroop 效应”相关活动。这些结果可能表明,与健康对照组相比,IAD 组的反应抑制过程效率降低。
