精选外刊|大脑越老越迟钝?真相出乎意料

** Why you really do get wiser and cleverer with age **
A new study published in the journal Scientific American has confirmed what older people have known for generations — far frombecoming slow, mushy thinkers as we age, our mature brains mean we have more to offer than at any earlier time in our lives.

“The brief about older people is that they’re all kind of the same; that they’re doddering, and that ageing is this steady downwards slope, “ says Laura Carstensen, founding director of the Stanford Centre on Longevity.

“That view is a great misunderstanding.”

So what are the reasons behind this?

The rise of the ‘emotional brain’

As we age, the risk-taking element of our brain starts to fade, and we are less controlled by the dictates of our hormones — and a more sophisticated mental acuity replaces this.

Feeling more emotionally stable

Those with experience are more sure of themselves and less swayed by the prevailing views of society.

“I don’t care so much about what people think of me, “ says Louise, 68.

“I am not stripped of all ambition, but my ambitions have definitely changed to be more specific to what I actually care about — rather than what might impress others.

I am less critical of others, vocally and internally.”

Having a greater sense of overall well-being

Mick, 72, finds a relief in no longer having to be on the treadmill of work and professional achievement.

“Eventually there’s a calmness, which brings with it a readiness to take a longer view, “ he says.

“Whatever daily travails my children and grandchildren face, I can see that in the long term they’ll be all right.

They are loved and have resources, so I feel reassured.

Perhaps that is what people mean when they talk about the wisdom of age.”

发表在《科学美国人》杂志上的一项新研究证实了老年人世代以来都知道的事实——衰老非但不会让我们的思维变得迟钝和多情,相反,我们成熟大脑意味着,我们能提供的东西,比这一生早些任何时候都多得多。
"The brief about older people is that they're all kind of the same; that they're doddering, and that ageing is this steady downwards slope," says Laura Carstensen, founding director of the Stanford Centre on Longevity. "That view is a great misunderstanding."
斯坦福大学长寿研究中心创始主任劳拉·卡斯滕森说道:“关于老年人的简单说法是:他们都差不多;他们都年老体衰;并且衰老是一条一路向下的斜坡。这种观点是一种极大的误解。”
So what are the reasons behind this?
那么,这背后的原因是什么呢?
The rise of the 'emotional brain'
“情感大脑”的崛起
As we age, the risk-taking element of our brain starts to fade, and we are less controlled by the dictates of our hormones — and a more sophisticated mental acuity replaces this.
随着年龄的增长,大脑中的冒险元素开始消退,我们不似以往那般受荷尔蒙的支配,取而代之的是更为复杂的敏锐心智。
Feeling more emotionally stable
感到情绪更加稳定
Those with experience are more sure of themselves and less swayed by the prevailing views of society. "I don't care so much about what people think of me," says Louise, 68.
有人生阅历的人对自己更有信心,也不那么容易被社会主流观点所左右。“我不怎么在意别人对我的看法,”68 岁的路易丝说道。
"I am not stripped of all ambition, but my ambitions have definitely changed to be more specific to what I actually care about — rather than what might impress others. I am less critical of others, vocally and internally."
“我并不是完全没了野心,但我追求的东西肯定是发生了变化,变得更加得具体,转移到了我真正关心的事情上去了,而不是那些可以拿去向别人炫耀的事情。我对他人的批评,无论是直言不讳说出来的还是心里想的(但没说的),都少了。”
Having a greater sense of overall well-being
整体幸福感更强
Mick, 72, finds a relief in no longer having to be on the treadmill of work and professional achievement. "Eventually there's a calmness, which brings with it a readiness to take a longer view," he says.
现年 72 岁的米奇如今不再需要在工作和职业成就的“跑步机”上奔波,这让他如释重负。他说:“最终我平静了下来,让我愿意把目光放得更长远。”
"Whatever daily travails my children and grandchildren face, I can see that in the long term they'll be all right. They are loved and have resources, so I feel reassured. Perhaps that is what people mean when they talk about the wisdom of age."
“无论我的孩子和孙子们每天面临什么难题,我都能看到,从长远来看,他们会好起来的。他们拥有爱,也有资源,所以我感到放心。也许这就是人们所说的长者智慧吧。”

大脑的变化
无论年龄, 海马体都是人体中重要的记忆脑区。在年轻时, 海马体专注于分离记忆中的经验。例如, 它帮助我们轻松地记住两次家庭旅行中发生的不同的事情。到了老年, 它转而使我们更容易注意到当前家庭旅行和过去旅行之间的共同点。
除了海马体工作方式的变化之外, 老年人的大脑也比年轻人的大脑更有可能拥有相互连接和合并的细胞网络。你可以认为老年人大脑中的信息是沿着蜿蜒曲折、相互连接的城市道路行驶的, 可以用来到达多个思想目的地, 而年轻人大脑中的信息则是在高速的州际公路上行驶, 每个出口都通向一个特定的思想目的地。
老年人的大脑倾向于使用相同的路线进行多种类型的思考, 这可以使他们更容易跟踪各种情况之间的重叠部分。这种注意到共同点的能力非常有用, 一部分是因为它可以更轻松地将在一种情况下学到的知识应用到新情况中。
