从内观察人类的大脑

What if we could look inside human brains? - Moran Cerf

大脑是我们所有想法
The brain is the center of all of our thoughts,

dreams,
情感
emotions,
和记忆存在的中心
and memories.
它让我们成为我们
It’s what makes us who we are.
但我们对大脑还是所知甚少
But, there is still a lot that we don’t know about the brain.
科学家们常年努力
Scientists have worked for years
试着运用脑电图和功能性磁共振成像技术
on trying to understand the human brain
从外部扫描的手法
using techniques like EEG and FMRI,
来理解人类的大脑
where we scan the brain from the outside.
但要是我们能从人脑的内部
But what if we could look inside the brains of humans
来一探它的运作方式呢
and watch them as they work?
恩 其实现在可以了
Well, now we can
通过观察那些
by looking at the brains of people
由于临床因素 如治疗癫痫而需要进行
who are already going through surgery for clinical reasons,
外科手术的人们
like curing epilepsy.
癫痫是一种
Epilepsy is a disease
大脑的无效区由于
in which a faulty part of the brain
不明原因开始自主运作的疾病
starts working spontaneously for no apparent reason.
它就像一次大地震
It’s like an earthquake
但却发生在你的头内
but inside your head.
没有办法能预测
There’s no way to know in advance
癫痫何时会发作
when a seizure will occur,
所以癫痫病人会始终处在
so the patients are always at risk
身体突然失控的风险之中
of unexpectedly losing control.
有专门治疗癫痫的药物
There are drugs that treat epilepsy,
但它并非始终有效
but these don’t always work.
那些药物疗效不明显的人们
Some patients who don’t respond well to the drugs
可以有另一种治疗方法
can undergo a different treatment
就是将大脑的无效区
where the faulty part in their brain,
可引起癫痫的那一部分
the part that starts the seizures,
通过手术切除
is surgically removed.
而困难之处就是如何知道该切除哪一部分
The challenge is knowing which part to take out.
你怎么知道大脑的某一部分就是无效区?
How do you figure out which bit of the brain is faulty?
为了找到这个无效区的准确位置
In order to find the exact location of the seizure onset,
医生们将电极植入病人的大脑的
doctors embed electrodes directly into the patient’s brain
疑似癫痫发作中心
around the suspected seizure center.
病人会在医院中呆上几天
The patient then stays in the hospital for a few days,
等待癫痫的发作
waiting to have a seizure
同时电极持续记录下
with the electrodes constantly recording
其大脑的活动情况
the activity inside his or her brain.
对 现在我们希望病人能癫痫发作
Yes, now we want the patient to have a seizure
这样医生们就可以用植入的电极
so doctors can use the embedded electrodes
观测它 找出它的确切根源
to measure it and learn exactly where its origin was.
在确知了癫痫
After doctors are sure where the seizures
在大脑中的来源后
come from in the brain,
医生们就可以移除电极了
they can take the electrodes out.
现在他们知道了大脑的什么部分该被去除
Now they know what part of the brain they can remove
以治愈病人
in order to cure the patient.
但这些脑电极不只能告诉我们
These brain electrodes can tell us
癫痫发作的根源地
more than just where the seizures happen.
基于医生植入电极的位置
Based on where the doctors place the electrodes in the brain,
我们可以了解大脑做了些什么
we can ask questions about what the brain does.
有时候我们会发现在每一次病人看特定的一幅图片时
Sometimes we find one cell that starts bursting in activity
病人的某一个细胞会突然活跃起来
every time the patient sees a particular picture,
比如 玛丽莲•梦露的图片
for example, a picture of Marilyn Monroe.
看 每次这个病人看见玛丽莲•梦露时
See, every time the patient sees Marilyn Monroe,
一些特定的细胞就会活跃起来
some specific cells fire in the brain.
现在你就能知道这个病人何时在想着她了
You can now know when the patient is thinking of Marilyn Monroe
仅仅通过听这些细胞何时被激发
just by listening to these cells fire.
当我们在每个病人身上找到若干个这样的细胞
When we find one or a few of these cells with each patient,
我们就可以做很多不可思议的事情
we can then do all kinds of fancy things.
比如 我们可以将记录电极与
For example, we can connect the recording electrode
一个显示屏相连
to a cursor on a screen
让病人可以通过想一些事情来
and have the patient move the cursor left or right
控制鼠标左右移动
just by thinking of things.
这技术可以帮助
This can help people
那些失去手臂控制能力的人
who lost the ability to move their hands,
比如脊髓受损的人和受伤的士兵
like people with spinal cord injuries or wounded soldiers,
让他们可以直接用大脑
by having them control a prosthetic arm
来控制义肢
directly with their brain.
我们的大脑是一个可以
Our brain is a brilliant device
对未来作出预测的绝妙设备
which can make predictions about the future.
例如 我们都能知道
For example, we can all know
哪一个字会出现在这句话的结……
which word will appear at the end of this…

sentence.
大脑可以解决复杂的问题
The brain can solve complicated problems,
想象整个宇宙
imagine the entire universe,
把握例如无穷和
and grasp concepts such as infinity
独角兽的概念
or unicorns.
大脑产生诸如爱和嫉妒的情感
The brain produces complex emotions like love or jealousy,
它让我们富有创造力和好奇心
it’s what makes us creative and curious,
它甚至能思考有关它自己的事
and it can even contemplate about itself.
且大脑正是我们用于研究大脑的器官
And the brain is the organ we use to study the brain.
我认为大脑是我们身体中最美的器官
I think that the brain is the most beautiful organ in our body,
但我又不禁问自己
but then I ask myself,
“是哪个器官让我有这想法的?”
“Which organ is making me think that?”
