An anonymous reader shares a report:Playing first-person shooter video games causes some users to lose grey matter in a part of their brain associated with the memory of past events and experiences, a new study by two Montreal researchers concludes. Gregory West, an associate professor of psychology at the Universite de Montreal, says the neuroimaging study, published Tuesday in the journal Molecular Psychiatry, is the first to find conclusive evidence of grey matter loss in a key part of the brain as a direct result of computer interaction. "A few studies have been published that show video games could have a positive impact on the brain, namely positive associations between action video games, first-person shooter games, and visual attention and motor control skills," West told CBC News. To date, no one has shown that human-computer interactions could have negative impacts on the brain -- in this case the hippocampal memory system." The four-year study by West and Veronique Bohbot, an associate professor of psychiatry at McGill University, looked at the impact of action video games on the hippocampus, the part of the brain that plays a critical role in spatial memory and the ability to recollect past events and experiences.
