Here is good news for those video game lovers! According to a research conducted on the effects of video game playing on brain reveals that the brain functions more efficiently after playing video games for three months. This research was conducted earlier in the year 1992 by Richard Haier, a neurologist at the University of California in Irvine. Recently, Haier now working as a consultant with Blue Planet Software, the company that markets ‘Tetris’ asked him to follow up on his 17 year old research.


In the earlier research, Haier looked at how it changed the player’s brain functions after frequent sessions with the Tetris video game. He believed that video game training could enhance brain functions. In the most recent research conducted by Haier along with three new colleagues came up with an experiment that cost $100,000.


The team conducted the research on a group of 26 adolescent girls aged between 12 and 15. Apparently, adolescents were selected as their developing brains tend to reflect changes often. Girls were particularly selected as they have less experience with video games as compared to the boys. Both the groups were monitored for changes in brain function as well as brain structure. They were however, divided into ‘experimental group’ and the ‘control group’.


The researches found that the former group’s brains function more efficiently in areas linked to critical thinking than the latter group’s. This is quite an interesting thought. Haier states that he is also interested in finding out how the different areas of the brain interact during the mental training on a time scale of milliseconds.
