COMMENTS: In this study college students played Internet video games for 6 straight weeks. Before and after measures were done. The ones with the highest cravings also had the most changes in their brains that indicate early addictions process. The control group, which played a less stimulating game, had no such brain changes.
Changes in cue induced prefrontal cortex activity with video game play.

Răspunsurile creierului, în special în cortexurile orbitofrontale și cingulate, la indicațiile de joc pe internet la studenții de la colegiu sunt similare cu cele observate la pacienții cu dependență de substanțe ca răspuns la indiciile legate de substanțe.
In this study, we report changes in brain activity between baseline and following 6 weeks of Internet video-game play. We hypothesized that subjects with high levels of self-reported craving for Internet video-game play would be associated with increased activity in the prefrontal cortex, particularly the orbitofrontal and anterior cingulate cortex.
Twenty-one healthy university students were recruited. At baseline and after a 6-week period of Internet video-game play, brain activity during presentation of video-game cues was assessed using 3T blood oxygen level dependent functional magnetic resonance imaging. Craving for Internet video-game play was assessed by self-report on a 7-point visual analogue scale following cue presentation.
În timpul unei perioade standard de redare a jocurilor video în săptămâna 6, activitatea creierului în cortexul anterior cingulate și orbitofrontal al grupului excesiv de jocuri pe internet (EIGP) a crescut ca răspuns la indiciile jocurilor video pe internet. În schimb, activitatea observată în grupul general de jucători (GP) nu a fost modificată sau scăzută.
In addition, the change of craving for Internet video games was positively correlated with the change in activity of the anterior cingulate in all subjects. These changes in frontal-lobe activity with extended video-game play may be similar to those observed during the early stages of addiction.
