Extensive video gaming is linked to brain changes in gamers playing 3 hours daily. These alterations may indicate reduced self-control and enhanced visual-motor skills, potentially informing Internet Gaming Disorder research.

Area of Science:

Neuroscience
Cognitive Psychology
Behavioral Science

Background:

Video gaming's impact on brain morphology is studied in occasional players and those with Internet Gaming Disorder (IGD).
Extensive gamers (approx. 3 hours/day) represent a distinct group, potentially offering insights into early markers of IGD.

Purpose of the Study:

To investigate brain morphology differences in extensive gamers compared to non-gamers.
To explore potential links between extensive gaming, prefrontal cortex structure, and visuomotor region development.

Main Methods:

A between-subject design comparing 26 extensive League of Legends (LOL) players with 26 matched non-gamers.
Utilized voxel-based morphometry, deformation-based morphometry, cortical thickness, and sulcus depth analyses.

Keywords:

Brain morphology Extensive video gaming Prefrontal cortex Superior parietal lobule Video games

Main Results:

Extensive gamers showed reduced gray matter in the ventromedial and dorsolateral prefrontal cortex.
Enlarged gray matter was observed in the left superior parietal lobule for extensive gamers.
Findings suggest alterations related to impulse control and visuomotor processing.

Conclusions:

Extensive gaming, particularly in Massive Multiplayer Online Battle Arena (MOBA) games, is associated with specific brain morphology changes.
These changes may reflect a balance between diminished inhibitory control and enhanced visuomotor abilities.
Results have implications for understanding IGD development and potential interventions.
