Brains Video Games Reward Them More

Brains Video Games Reward Them More, Teenagers who spend a lot of time on video-games have different structures and activity levels in areas of the brain that are linked to reward, scientists have found, suggesting they get more out of gaming than people who tend to play less.
In a study published in the Translational Psychiatry journal on Tuesday, researchersanlyzed MRI scans of more than 150 14-year-olds who played video-games either moderately or a lot, and found the frequent gamers had a higher volume of grey matter in a key part of their brains.
Previous studies have shown a link between the dopamine-related ventral striatum, a structure of the brain’s reward system, and video-gaming or computer gambling, but this is the first to look at brain structure and volume.
“These findings demonstrate that the ventral striatum plays a significant role in excessive video-game playing and contributes to our understanding of behavioral addiction,” Simone Kuehn of Belgium’s Ghent University and Juergen Gallinat of Germany’s Charite University Medicine wrote in their study
Video-gaming has become hugely popular in recent years, particularly among teenagers. The average weekly usage in this experiment was around 12 hours a week.
There is an ongoing debate among doctors and researchers about whether excessive video-gaming should be recognized as an addiction and seen as a form of mental disorder.
While the German researchers found keen gamers had structural differences in their brains compared to those who played less frequently, they were not able to say whether this was a cause of eagerness to play video-games or a change that had come about as a result of their habit.
Henrietta Bowden-Jones of the neuroscience division at Imperial College London said the findings were highly relevant to clinicians because they “further close the gap” between video-gaming and other addictions, giving specialists a better understanding of possible long-term treatment options.
