KOMMENTAAR: Breinstudie oor videospelers. Soos met alle ander studies het dit verskille getoon tussen kontrolegroepe en diegene wat videospeletjies "oorbenut". Breinmetabolismepatrone boots dié met substansverslawing na.

Abstract
Inleiding: Internet game overuse is an emerging disorder and features diminished impulse control and poor reward-processing. In an attempt to understand the neurobiological bases of Internet game overuse, we investigated the differences in regional cerebral glucose metabolism at resting state between young individuals with Internet game overuse and those with normal use using 18F-fluorodeoxyglucose positron emission tomography study.
Metodes te gebruik: Twenty right-handed male participants (9 normal users: 24.7+/-2.4 years of age, 11 overusers: 23.5+/-2.9 years of age) participated. A trait measure of impulsivity was also completed after scanning.
Results: Internet game overusers showed greater impulsiveness than the normal users and there was a positive correlation between the severity of Internet game overuse and impulsiveness. Imaging data showed that the overusers had increased glucose metabolism in the right middle orbitofrontal gyrus, left caudate nucleus, and right insula, and decreased metabolism in the bilateral postcentral gyrus, left precentral gyrus, and bilateral occipital regions compared to normal users.
Gevolgtrekking:
Oorgebruik van internetspeletjies kan geassosieer word met abnormale neurobiologiese meganismes in die orbitofrontale korteks, striatum en sensoriese streke, wat betrokke is by impulsbeheer, beloningsverwerking en somatiese voorstelling van vorige ervarings. Ons resultate ondersteun die idee dat internetspeletjie-oorgebruik sielkundige en neurale meganismes deel met ander tipes impulsbeheerafwykings en substans-/nie-stofverwante verslawing.
