Abstract
AIM:
The present study aimed to evaluate the brain correlates of response inhibition among subjects with internet gaming disorder (IGD).
METODE:
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 (fMRI) investigation. Prior to scanning, the subjects were assessed using the Chen Internet Addiction Scale and the Barrett Impulsivity Scale.
REZULTATE:
The control group exhibited activation of the right supplement motor area, dorsolateral prefrontal cortex, and caudate for response inhibition. However, the IGD group had a higher impulsivity and lower activity of the right supplement motor area (SMA)/preSMA in comparison to the control group.
CONCLUZIE:
The results obtained ssuggest that dysfunctional activation of the supplement motor area for response inhibition is one of the candidate mechanisms of IGD.
