  • When I'm playing Assassin's Creed or Call of Duty, my brain is totally absorbed in this virtual environment.

  • But what happens to my brain when I come out of it? Does it come out different?

  • This week, we humans will spend 3 billion hours playing video games,this week, 1.2 billion people

  • play regularly... 99 percent of boys and 94 percent of girls under 18 lock their eyeballs

  • on a video game quote "regularly" according to game designer and author Jane McGonigal.

  • That's an incredible amount of time living in what amounts to an alternate reality for

  • the brain.

  • A study from the Proceedings of the Royal Society B that came out last December

  • looked at the brains of gamers while playing and offer another alleged turn in the thumbscrews of action games

  • Their study found that video game players have a less robust striatum nucleus --

  • the part of the brain that constructs an internal representation of the outside world.

  • Essentially, games aren't helping people learn to map the real world out here.

  • Action gamers are using something called "response learning" instead of

  • the more advanced "place learning."

  • To simplify, imagine you're trying to get to a familiar place like a friend's house

  • or your favorite restaurant: "response learning" is when your brain creates a map using landmarks;

  • but "place learning" is an advanced internal map so you know to turn based on distance

  • and direction --not just like, there's a McDonalds right there. it's the difference between associating lots of little bits of information

  • … "I have to turn when I see the McDonalds" as opposed to combining that information into

  • an understanding of the external world.

  • These researchers think the action video game players are under-developing their striatum

  • to such a degree that it might affect them throughout their lives; they may even develop

  • a neurological disorder because of this! Some news outlets have called this a risk of Alzheimers, but

  • that's a pretty damn big jump.

  • For every study of games negatively affecting our brains there are

  • plenty of studies saying the opposite. A study in July of last year in Molecular Psychiatry

  • put gamers into magnetic resonance imagers to reveal how grey matter was developing in

  • their cabezas. They found a correlation in the size of their grey matters, specifically the entorhinal cortex, and left

  • occipital cortex/inferior parietal lobes related to their 'joystick years' or the amount of

  • time they played certain video games.

  • According to their results, people who played more logic, puzzle, and platform games had

  • a larger entorhinal cortex, but action-based role-playing games had a smaller one. The

  • entorhinal cortex works with the hippocampus to create memories and maps of your life -- so

  • you know when and where something happened as well as how it fits in with what happened

  • the day before, or last time you met that person. Another study in that journal from

  • February of the same year found similar results using games like Commander Keen and Super

  • Mario 64. Science is saying, platformers and logic games are great for the entorhinal cortex,

  • even while action-based games aren't.

  • That being said, however, the hippocampus and grey matter in ALL video game players

  • had added brain plasticity overall! Plasticity is the ability for the brain to adapt and change

  • neural pathways. More plasticity is better! And it's not just the plasticity, a study

  • done with chimpanzees published in Science News last month assessed how chimps' brains

  • responded to playing video games. After teaching them to play a cooperative game, the researchers

  • found cells in the chimp's brains would fire, predicting what the next move of the OTHER chimp playing with them would be 79.4

  • percent of the time! These chimps understood what was going on in the brains of their co-op

  • players.

  • We KNOW video games change how our brain works, but whether that's a good or bad thing seems

  • to change as new research comes outwhich is every month. We cover this research all the time. For instance,

  • do videogames make you more aggressive? Joe Bereta explores that idea in this episode
