[Still Thinking]

"We, however, also found action video game players use navigation strategies that rely on the caudate nucleus to a much greater degree than non video game players. Past research has shown people who rely on caudate nucleus dependent strategies have lower grey matter and functional brain activity in the hippocampus."

Doesn't address causality. Maybe video games appeal to "caudate thinkers". Wouldn't change the fact that avid players might be more at risk of Alzheimer's, if in fact that's true, but knowing whether gaming was causal would tell them whether to tone it down or not.

I have no idea what the various types of thinkers are. But years ago I tried to play it with my son over at a neighbor’s house. I sucked! (The neighbors 8 year old thought I was funny though!)
