摘要
AimsThe present study aimed to evaluate the brain correlates of response inhibition among subjects with Internet gaming disorder (IGD). MethodsFor this purpose, 15 men with IGD for at least 1 year, and 15 controls with no history of IGD were recruited to perform the Go/Nogo task under functional magnetic resonance imaging investigation. Prior to scanning, the subjects were assessed using the Chen Internet Addiction Scale and the Barrett Impulsivity Scale. ResultsThe control group exhibited activation of the right supplement motor area (SMA), dorsolateral prefrontal cortex, and caudate for response inhibition. However, the IGD group had a higher impulsivity and lower activity of the right SMA/pre-SMA in comparison to the control group. ConclusionsThe results obtained suggest that dysfunctional activation of the SMA for response inhibition is one of the candidate mechanisms of IGD.
