還記不記得你媽媽經(jīng)常朝你大喊大叫，說總玩電子游戲會變傻?現(xiàn)在有科學(xué)家發(fā)現(xiàn)媽媽們錯了。一項新的研究顯示，連續(xù)兩個月每天玩半個小時“超級瑪麗64”能讓大腦容積“顯著”增大。

研究中提到的因果關(guān)系非常驚人。領(lǐng)導(dǎo)此次研究的Simon Kühn說，“雖然以前的研究顯示玩電子游戲會造成大腦結(jié)構(gòu)不同的改變，目前的這項研究顯示了電子游戲和大腦體積增大之間的直接因果關(guān)系。”

“這證明大腦的特定區(qū)域可能通過電子游戲來進行訓(xùn)練。”這對于治療士兵的“創(chuàng)傷后精神緊張性精神障礙”(PTSD)或類似疾病是非常有效的。

這條新聞確實看起來不錯，但是也別高興地太早。這項研究的樣本很小，只有23名成年人，所以不是每個人都會得到相同的結(jié)果。另外，玩太多的電子游戲確實會導(dǎo)致大腦某一部分的萎縮。所以，你媽媽的話也不完全都是錯的。

Playing Super Mario 64 Makes Your Brain Bigger

You know how your mom used to yell that playing video games would turn your brain into mush? Turns out she was exactly wrong. A new study

shows that playing Super Mario 64 for half an hour a day over the course of two months causes a "significant" increase in brain size。

What makes this study compelling is that causation bit. "While previous studies have shown differences in brain structure of video

gamers, the present study can demonstrate the direct causal link between video gaming and a volumetric brain increase," says study leader Simon Kühn. "This proves that specific brain regions can be trained by means of video games." And that's a really good thing when it comes to stuff like helping soldiers recover from PTSD。

This is neat news, but don't go crazy with it. The study was relatively small—just 23 adults—so not everybody will get the same results. Plus, playing too many video games can actually make certain parts of your brain shrink. So actually, your mom was half right。
