A new study reveals how playing video games not only changes how our brain functions, but also the structure of the brain. Scientists have collected and summarized studies looking at how video games can shape our brains and behavior. Research to date suggests that playing video games can change the brain regions responsible for attention and visuospatial skills and make them more efficient. The researchers also looked at studies exploring brain regions associated with the reward system, and how these are related to video game addiction.
The studies show that playing video games can change how our brains perform, and even their structure. For example, playing video games affects our attention, and some studies found that gamers show improvements in several types of attention, such as sustained attention or selective attention. The brain regions involved in attention are also more efficient in gamers and require less activation to sustain attention on demanding tasks. There is also evidence that video games can increase the size and efficiency of brain regions related to visuospatial skills.
