PLoS One:玩“3D超级玛丽”可以使大脑保持良好状态

2017-12-12 佚名 中国生物技术网

关于电脑游戏的神经学和心理学影响,总是存在很多争论。一些研究认为,暴力游戏和攻击性之间存在关联,但是此类研究的结果常常前后矛盾,还有很多研究得出相反的结论。更有趣的是,最近的研究表明,电脑游戏能够改善认知功能。现在,加拿大蒙特利尔大学的研究人员们发现,玩3D游戏(比如超级马里奥64)的人在游戏之后大脑海马体中灰质变多了。该研究包括了各个年龄段的受测者,已发表在近日的《PLOS ONE》上。

关于电脑游戏的神经学和心理学影响,总是存在很多争论。一些研究认为,暴力游戏和攻击性之间存在关联,但是此类研究的结果常常前后矛盾,还有很多研究得出相反的结论。更有趣的是,最近的研究表明,电脑游戏能够改善认知功能。现在,加拿大蒙特利尔大学的研究人员们发现,玩3D游戏(比如超级马里奥64)的人在游戏之后大脑海马体中灰质变多了。该研究包括了各个年龄段的受测者,已发表在近日的《PLOS ONE》上。

过去的研究也发现了类似的结果,但是只关注了20多岁的年轻男性,因为他们是电脑游戏的主要玩家,但是并不具有代表性。

现在,他们对老年人也进行了类似的研究。他们招募了33名55至75岁的受测者,并将他们分为三组:第一组定期玩超级马里奥64,第二组参加钢琴课,第三组什么也不做。

第二组和第三组受测者的大脑中灰质没有增加,但是第一组受测者的灰质增加了。研究人员Gregory West说,类似超级马里奥这样的游戏迫使玩家建立一个虚拟环境的认知地图,而这会刺激海马体。这种方法可以帮助逆转灰质萎缩,这种症状通常随着衰老而出现。

West说:“好消息是,我们可以逆转这些影响,通过学习新东西来增加灰质体积,比如像超级马里奥64 这样的游戏,它能够刺激海马体,具有这方面的潜力。我们还需要确定,是与空间记忆相关的大脑活动影响大脑可塑性,还是只要学习新事物就能够产生这种作用。”

海马体中的灰质对于中枢神经系统至关重要,而且只存在于海马体中,它负责将短期记忆转化为长期记忆和空间定位。海马体中的灰质也是神经和精神类疾病的重要生物标志物,包括阿尔兹海默症。

虽然我们对待此类研究结果应该谨慎,但是这个结果确实令人振奋。它表明,玩游戏什么时候都不嫌老,至少对于海马体来说是这样的,它比学习弹钢琴更合适。
