Summary

Brain activity in response to Internet video game cues shows changes similar to substance dependence. Excessive gaming increased activity in the prefrontal cortex, linked to craving and potential addiction.

Area of Science:

  • Neuroscience
  • Psychology
  • Addiction Research

Background:

  • Internet video-game cues can elicit brain responses similar to substance-related cues in substance-dependent individuals.
  • Understanding the neural correlates of excessive Internet video-game play is crucial for identifying early signs of addiction.

Purpose of the Study:

  • To investigate changes in brain activity in college students after 6 weeks of Internet video-game play.
  • To examine the relationship between self-reported craving for Internet video games and brain activity in response to game cues.

Main Methods:

  • Functional magnetic resonance imaging (fMRI) was used to assess brain activity in 21 university students before and after a 6-week video-game play period.
  • Brain responses to video-game cues were measured using 3T blood oxygen level dependent (BOLD) imaging.

  • Self-reported craving was assessed using a visual analogue scale.

    • Main Results:

    • The excessive Internet game-playing group (EIGP) showed increased activity in the anterior cingulate and orbitofrontal cortex in response to game cues.
    • The general player group (GP) exhibited no significant change or a decrease in activity.
    • Changes in anterior cingulate activity were positively correlated with changes in craving for Internet video games across all subjects.

    Conclusions:

    • Extended Internet video-game play can lead to changes in frontal lobe activity, particularly in the orbitofrontal and anterior cingulate cortex.
    • These neural changes in excessive gamers resemble those seen in the early stages of addiction.
    • Increased prefrontal cortex activity and craving suggest a potential for developing problematic gaming behaviors.
