Researchers Found Action Games Can Impact Brain Matter

For many years people have been studying what impacts video games can have on humans and producing various results. New researchers at McGill University have found that action games can actually lead to a loss of grey matter in the hippocampus, though what long-term consequences this may entail require further study. However, playing 3D-platform games, like Super Mario 64, can actually increase the amount of grey matter.

For this study the researchers had 64 participants ranging in age from 18 to 30 and had them play 90 hours of different kinds of games. These games included first person shooters like Call of Duty, Killzone, Medal of Honor, and Borderlands 2, along with the previously mentioned Super Mario 64, and the participants had not played these games previously. The researchers found that for some of those playing the FPS games, the hippocampus lost grey matter after 90 hours, while no one lost any while playing the 3D platformer, or even saw an increase. There is more to it than this though as the researchers found the loss of grey matter also depended on the kind of learner people are. Response learners, who will follow their brain's autopilot and reward system for navigation, experienced the loss while spatial learners who use the hippocampus to navigate saw an increase in grey matter. It is not just a matter of the kind of game you are playing but also how you learn. The increase seen from Super Mario 64 occurred for both types of gamers.

Exactly what about this genre causes this atrophy is still unknown and will require further study, as will determining the long-term consequences of this loss. People with lower amounts of grey matter in the hippocampus though are known to be at an increased risk of neuropsychiatric illnesses, such as depression, schizophrenia, PTSD, and Alzheimer's disease.

Fascinating stuff. I still do a lot of board PC games and Angry birds (PC version) but play less Doom3, Hamo, etc. Wonder how they affected me. Still have my intelligence, or, maybe I am kidding myself. :-)
