Does Frequent Video Game Playing Alter the Brain?


Nov. 15, 2011 -- Kids who spend hours a day playing video games may be hardwired to behave that way -- or their brains may have been altered as a result of all the gaming.

The answer is not yet clear, but when researchers compared the brains of 14-year-olds who played video games excessively to those who played less often, they found key differences in an area of the brain associated with reward and addiction.

The brain imaging study revealed that the structure and activity in the part of the brain associated with reward processing was bigger in frequent gamers.

Specifically, an area of the brain known as the ventral striatum -- considered key to motivation and reward -- had more gray matter in kids who played video games nine hours or more a week compared to those who spent less time gaming.

It was not clear if playing video games led to the increase or if kids with larger volumes of ventral striatum were more drawn to video games in the first place.

Researcher Simone Kuhn, PhD, of the University of Ghent in Belgium, says more research is needed to tease this out. But she says that it may be that people with larger ventral striatum volumes might derive more pleasure from playing video games.
