Aims:
The present study aimed to evaluate the brain correlates of response inhibition among subjects with Internet gaming disorder (IGD).
Methods:
For 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.
Results:
The 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.
Conclusions:
The results obtained suggest that dysfunctional activation of the SMA for response inhibition is one of the candidate mechanisms of IGD.
