Charles Limb: Your brain on improv

翻译人员: Jenny Yang 校对人员: Angelia King

我是一个研究创造力的手术医生，

So I am a surgeon who studies creativity,

and I have never had a patient tell me,

从来没病人跟我说

"I really want you to be creative during surgery,"

“我真希望你在手术时搞些创造。”

and so I guess there's a little bit of irony to it.

所以我想这也是有点讽刺的。

I will say though that, after having done surgery a lot,

我是说，做了那么多手术后，

it's similar to playing a musical instrument.

就跟演奏一种乐器一样。

And for me, this deep and enduring fascination with sound

对我来说， 对声音的持久而深切的痴迷

is what led me to both be a surgeon

引导我成为一个手术医生，

and to study the science of sound, particularly music.

并研究声学，特别是音乐的。

所以我想在随后的几分钟里

I'm going to talk over the next few minutes

我来讲一下我的职业

about my career

in terms of how I'm able to study music

我是怎样研究音乐

and try to grapple with all these questions

怎样研究大脑是如何进行创造

of how the brain is able to be creative.

等问题的。

I've done most of this work at Johns Hopkins University,

我的大部分的工作是在約翰斯霍普金斯大学进行的，

and at the National Institute of Health where I was previously.

也有些是在我原先工作的国家健康研究所完成的。

我在这里给大家介绍一些科学实验

I'll go over some science experiments and cover three musical experiments.

包括三个音乐实验。

我先给大家看一段录像。

I will start off by playing a video for you.

这是基思·杰瑞特Keith Jarrett的一段录像，他是著名的即兴爵士作曲家，

This video is of Keith Jarrett, who's a well-known jazz improviser

估计他也是能将即兴创造升华到非常高超境界

and probably the most well-known, iconic example

的最著名，最有代表性的人物。

of someone who takes improvisation to a higher level.

他可以即兴表演一场音乐会

And he'll improvise entire concerts off the top of his head,

音乐就在他的大脑里即兴产生，

and he'll never play it exactly the same way again,

他不会再用同样的手法演奏第二次。

所以，这是一种创作强度很高的一种形势，

so as a form of intense creativity,

我觉得这是一个很好的例子。

I think this is a great example.

And so why don't we go and click the video.

我们为什么还不点击这视频看看。

(Music)

(音乐)

(Music ends)

这真是很神奇，精彩的即兴音乐。

It's really a remarkable thing that happens there.

我是他的一个忠实的听众， 粉丝，

I've always as a listener, as a fan,

我听到这些会感到很震惊。

I listen to that, and I'm astounded.

I think -- how can this possibly be?

我想：这怎么可能？

How can the brain generate that much information,

大脑怎么可能产生这么大量的信息，

同时爆发出这么多音乐？

that much music, spontaneously?

And so I set out with this concept, scientifically,

所以我从这个概念出发，科学地认为

that artistic creativity, it's magical, but it's not magic,

艺术创作，是神奇的，但不是魔术。

它是大脑的产物。

meaning that it's a product of the brain.

很少有不动脑子的人创作艺术。

There's not too many brain-dead people creating art.

所以艺术创作的产生

With this notion that artistic creativity is in fact a neurologic product,

事实上是神经的产物，

I took this thesis that we could study it

我开始了这个研究课题

just like we study any other complex neurologic process,

就象研究其他复杂神经过程一样。

and there are subquestions that I put there.

我想我提出了一些潜在的问题。

Is it possible to study creativity scientifically?

我们是否能科学地研究创作力？

And I think that's a good question.

我觉得这是一个很好的问题。

And I'll tell you that most scientific studies of music,

我想告诉你大多数的音乐科学研究

they're very dense,

都很高深莫测。

and when you go through them,

你很难在那些研究材料中发现音乐。

it's very hard to recognize the music in it.

In fact, they seem to be unmusical entirely

事实上， 它们完全是非音乐的

and to miss the point of the music.

完全丧失了音乐性。

This brings the second question:

这就带来了第二个问题：

Why should scientists study creativity?

为什么科学家研究创造力？

Maybe we're not the right people to do it.

也许我们不是解答这问题的合适人选。

(Laughter)

也可能是，

Well it may be, but I will say that, from a scientific perspective,

但是我要说的是， 从科学的观点出发

we talked a lot about innovation today,

我们今天谈论了很多有关发明创造的话题--

the science of innovation,

科学发明，

how much we understand about how the brain is able to innovate

我们对大脑是如何创造的了解

才刚起步。

is in its infancy,

and truly, we know very little about how we are able to be creative.

其实，我们对我们是怎样创造的知之甚少。

I think that we're going to see,

所以我们会在

over the next 10, 20, 30 years,

今后的10，20，30年间看见

a real science of creativity that's burgeoning

一个真正现实的科学创造力会从兴起走向繁荣。

and is going to flourish,

Because we now have new methods that can enable us

我们现在有了新的手法帮助我们

将向这样的一个过程过渡，

to take this process like complex jazz improvisation,

一个复杂的即兴爵士乐创造的过程，并严格地分析研究它。

and study it rigorously.

所以说到大脑，

So it gets down to the brain.

我们所有的人都有一个非凡的大脑，

All of us have this remarkable brain,

至少现在来说，我们对它的了解是非常有限的。

which is poorly understood, to say the least.

I think that neuroscientists have more questions than answers,

我想神经学家

的问题比答案要多。

and I'm not going to give you answers today,

而我今天也没办法给你很多答案，

just ask a lot of questions.

只能提出很多问题。

And that's what I do in my lab.

这也是基本上我在实验室做的事情。

I ask questions about what is the brain doing to enable us to do this.

我追问到底大脑做了什么使得我们能做这些事情。

这是我用的主要方法，这是功能性的核磁共振成像。

This is the main method that I use. This is functional MRI.

如果你用过核磁共振成像扫描仪，它们是一样的，

If you've been in an MRI scanner, it's very much the same,

but this one is outfitted in a special way to not just take pictures of your brain,

但是这个有特殊的配备

所以它不只是给你的大脑拍照，

but to also take pictures of active areas of the brain.

而且给大脑活跃的区域拍照。

The way that's done is by the following:

整个完成的过程如下，

There's something called BOLD imaging,

这是叫做BOLD成像，

which is Blood Oxygen Level Dependent imaging.

它代表血液氧气水平成像。

现在如果你在功能性核磁共振扫描仪中，

When you're in an fMRI scanner, you're in a big magnet

你在一个大磁场里

that's aligning your molecules in certain areas.

这是和你的一些特别区域的分子对应。

When an area of the brain is active, meaning a neural area is active,

当大脑活跃时，也就是神经区域活跃时，

血液会往那个区域流动。

it gets blood flow shunted to that area.

That blood flow causes an increase in local blood to that area

血液流动会导致那个

区域的血液增加

with a deoxyhemoglobin change in concentration.

导致脱氧血红蛋白的浓度发生变化。

Deoxyhemoglobin can be detected by MRI,

核磁共振扫描仪可以探测脱氧血红蛋白，

但不能探测氧合血红蛋白。

whereas oxyhemoglobin can't.

So through this method of inference --

所以用这种手法来推理

and we're measuring blood flow, not neural activity --

我们测量血液的流动，不是神经的活动。

我们可以说大脑的某个部分得到了更多的血液，

we say that an area of the brain that's getting more blood

这个部分在人做某些事情时特别活跃。

was active during a particular task, and that's the crux of how fMRI works.

这就是功能磁共振成像的关键。

这从90年代就被使用

And it's been used since the '90s to study really complex processes.

用来研究复杂的过程。

I'm going to review a study that I did, which was jazz in an fMRI scanner.

现在我来介绍我做的一个研究

是关于爵士的功能磁共振成像。

It was done with a colleague, Alan Braun, at the NIH.

这是我和我的同事阿兰·布朗Alan Braun一起在国家健康研究所做的。

This is a short video of how we did this project.

这是我们如果做这个实验的一段录像。

(Video) Charles Limb: This is a plastic MIDI piano keyboard

(录像)查尔斯·林普Charles Limb: 这是一个塑料的MIDI琴键键盘

我们用它来做爵士实验。

that we use for the jazz experiments.

And it's a 35-key keyboard

它有35个键

designed to fit both inside the scanner,

是为了可以在扫描仪中使用而设计的，

它保证磁控安全，

be magnetically safe,

have minimal interference that would contribute to any artifact,

并将可能造成影响的人为干扰

减到最小，

and have this cushion so that it can rest on the players' legs

这个垫子可以放在演奏者的腿上，

while they're lying down in the scanner, playing on their back.

他们在扫描仪中，他们是躺着弹琴的。

It works like this -- this doesn't actually produce any sound.

这是像这样工作的，它并不产生声音。

It sends out what's called a MIDI signal --

它传递所谓的MIDI信号

也称为乐器数字界面，

or a Musical Instrument Digital Interface --

通过这个电线传到盒子和计算机中，

through these wires into the box and then the computer,

which then trigger high-quality piano samples like this.

然后产生了象这样高质量钢琴声。

(Music)

(音乐)

(音乐)

(Music)

(Music ends)

OK, so it works.

CL：好的， 它是这样工作的。

And so through this piano keyboard,

所以通过钢琴的琴键，

we have the means to take a musical process and study it.

我们可以有办法记录音乐的过程来进行研究。

所以你有了这个很酷的钢琴琴键后干什么呢？

So what do you do now that you have this cool piano keyboard?

You can't just say, "It's great we have a keyboard."

你不能说：“太好了，我们有了键盘了。”

我们得想出真正的科学实验。

We have to come up with a scientific experiment.

实验其实是由以下的内容组成的。

The experiment really rests on the following:

What happens in the brain during something that's memorized and over-learned,

大脑在人们靠记忆演奏熟知的音乐时是怎样反应的？

and what happens in the brain during something

大脑在演奏者自发和即兴创作

时又是如何反应的？

that is spontaneously generated, or improvised,

从某个角度来说这与肌肉运动相匹配

in a way that's matched motorically

并符合低级感知运动的特征吗？

and in terms of lower-level sensory motor features?

我这里有一段范例。

I have here what we call the paradigms.

There's a scale paradigm, which is playing a scale up and down, memorized,

这是一段音阶范例， 只需要跟了音阶上下， 记住就行。

而这是对这段音阶的即兴发挥，

then there's improvising on a scale,

quarter notes, metronome, right hand --

4分音符， 节拍器和右手，

scientifically very safe,

科学上来说很妥当，

but musically really boring.

但是从音乐上来说很单调。

Then there's the bottom one, which is called the jazz paradigm.

底下的这个，叫做爵士范例。

我们把专业的爵士乐演奏者请到国家健康研究中心，

So we brought professional jazz players to the NIH,

我们让他们记住左边的这段音乐，左下

and we had them memorize this piece of music on the lower-left,

就是你听到我弹的这段，

which is what you heard me playing --

然后我们让他们用同样的和音来即兴发挥。

and we had them improvise to the same chord changes.

如果你能按右下角的按钮，

And if you can hit that lower-right sound icon,

这就是扫描仪录下的例子。

that's an example of what was recorded in the scanner.

(音乐)

(Music)

(Music ends)

说到底，这并不是最自然的环境，

In the end, it's not the most natural environment,

但是他们能弹奏真的音乐。

but they're able to play real music.

我已经听了这段独奏200遍了，

And I've listened to that solo 200 times,

我还是喜欢它。

and I still like it.

And the musicians were comfortable in the end.

音乐家们最后也感到挺舒适。

我们首先测量音符数量。

We first measured the number of notes.

Were they playing more notes when they were improvising?

他们在即兴创作时会演奏很多音符吗？

结果不是这样。

That was not what was going on.

然后我们查看了大脑的活动。

And then we looked at the brain activity.

我来把这个给你们压缩在一起。

I will try to condense this for you.

这些对比图展示了大脑在

These are contrast maps that are showing subtractions between what changes

在你做即兴创作时

when you're improvising vs. when you're doing something memorized.

和你在做熟记的事情时的不同。

In red is an area that's active in the prefrontal cortex,

左前头叶外皮的一个活跃地区呈红色，

这是在大脑的前叶。

the frontal lobe of the brain,

and in blue is this area that was deactivated.

蓝色的地区是不活跃地区。

所以我们看到这个前额皮质一侧是一个焦点

So we had this focal area called the medial prefrontal cortex

活跃程度很高。

that went way up in activity.

我们可以看到这前额皮质的这一侧一大块

We had this broad patch of area called the lateral prefrontal cortex

活跃程度很低， 我在这里为你们总结一下。

that went way down in activity,

I'll summarize that for you.

这是大脑的多功能区域。

These are multifunctional areas of the brain,

像我说的那样， 这不是大脑的爵士部分。

these are not the jazz areas of the brain.

它们担当了很多的事情

They do a whole host of things

包括自省，

that have to do with self-reflection,

introspection, working memory etc.

内省， 工作记忆等。

人的意识其实是处于大脑前叶。

Really, consciousness is seated in the frontal lobe.

But we have this combination

但是我们发现这些联系在一起的

of an area that's thought to be involved in self-monitoring, turning off,

主管自我控制的区域关闭了，

而这个代表自传

and this area that's thought to be autobiographical,

自我表达的区域活跃起来。

or self-expressive, turning on.

所以我们想，至少初步是这么想，

We think, at least in this preliminary --

这只是一个研究， 可能是错误的。

it's one study; it's probably wrong, but it's one study --

但是这是一个研究成果。

(Laughter)

我想至少是一个合理的解说

we think that at least a reasonable hypothesis

就是， 要有创造力，

is that, to be creative,

you should have this weird dissociation in your frontal lobe.

你需要跟你的大脑前叶达成这种奇怪的分离。

一个区域打开了，一个大的区域关闭了，

One area turns on, and a big area shuts off,

因此你会感到不受局限的， 你愿意犯错，

so that you're not inhibited, you're willing to make mistakes,

而不是老是去停止尝试

so that you're not constantly shutting down

所有新创造的冲动。

all of these new generative impulses.

Now a lot of people know that music is not always a solo activity --

很多人都知道音乐不总是一个单独的活动，

有的时候它是通过沟通合作完成的。

sometimes it's done communicatively.

所以下面的一个问题是：

The next question was:

What happens when musicians are trading back and forth,

当音乐家们互相弹奏音乐时大脑是怎样活动的呢？

something called "trading fours,"

有种手法叫四小节交换，

which is something they do normally in a jazz experiment.

这是种在爵士乐中常用的方法吗？

这是一个12小节的爵士。

So this is a 12-bar blues,

and I've broken it down into four-bar groups,

这里我把它分成四小节一组，

so you would know how you would trade.

所以你知道怎么切换。

We brought a musician into the scanner, same way,

我们用同样的办法把一个音乐人安排到扫描仪中，

让他记住这段旋律

had them memorize this melody

then had another musician out in the control room

然后让另一个演奏者在控制室

跟他前后交互演奏。

trading back and forth interactively.

So this is a musician, Mike Pope,

这是那个音乐家，迈克·蒲柏Mike Pope，

one of the world's best bassists and a fantastic piano player.

世界上最好的贝斯手， 一个奇妙的钢琴手。

(Music)

他现在在弹的这一段

He's now playing the piece that we just saw

我们要看见的这一段

a little better than I wrote it.

只不过他弹得音乐比我写的音乐要好点。

(Video) CL: Mike, come on in.

(视频) CL：迈克Mile, 请进。 ( 男人：愿力量与你同在。)

Mike Pope: May the force be with you.

护士：你口袋里没其他东西吧，迈克Mike?

Nurse: Nothing in your pockets, Mike?

迈克·蒲柏Mike Pope: 没有， 我口袋里没东西。(护士：好的。)

MP: No. Nothing's in my pockets.

CL: You have to have the right attitude to agree to do it.

CL：你答应做这个实验时需要有正确的态度。

(笑声)

(Laughter)

It's kind of fun, actually.

这其实挺好玩的。

(Music)

现在我们开始互相交互弹奏。

Now we're playing back and forth.

他在里面， 你可以看见他的腿在那儿。

He's in there. You can see his legs up there.

(Music)

And then I'm in the control room here, playing back and forth.

而我在控制室， 我们弹来弹去。

(Music)

(音乐)

(Music ends)

(Video) Mike Pope: This is a pretty good representation

(视频)迈克·蒲柏Mike Pope:这很好的代表了

of what it's like.

演奏的状态。

And it's good that it's not too quick.

而且曲子不是太快，这很好。

The fact that we do it over and over again

我们之所以一遍又一遍地实验

是为了让你熟悉新的环境。

lets you acclimate to your surroundings.

那个头套对我来说，让我有点行动不便，

So the hardest thing for me was the kinesthetic thing,

looking at my hands through two mirrors,

我通过两边的镜子

看见我的手，

laying on my back,

我仰面躺着

and not able to move at all except for my hand.

除了手我完全不能动。

That was challenging.

这是很有挑战性的。

But again --

但是再说了，

有些时刻，真的，

there were moments, for sure --

有一些时刻

(Laughter)

there were moments of real, honest-to-God musical interplay, for sure.

你会感到绝对发自内心地，诚挚地与音乐交流，真的。

CL：到此， 我来回顾一下。

CL: At this point, I'll take a few moments.

你们到底看到了什么，

So what you're seeing here --

and I'm doing a cardinal sin in science,

而我在犯科学之大忌，

给你们展示初步的数据。

which is to show you preliminary data.

This is one subject's data.

这只是一个实验的数据。

This is, in fact, Mike Pope's data.

这是，事实上，迈克·蒲柏Mike Pope的数据。

So what am I showing you here?

所以我在这里给你看的是什么呢？

When he was trading fours with me, improvising vs. memorized,

当他在跟我交换四小节的演奏时， 靠的是即兴不是记忆，

他的语言部分亮了起来，他的布洛卡区域

his language areas lit up, his Broca's area,

in the inferior frontal gyrus on the left.

就是他左脑的前方下面的脑回。

He had it also homologous on the right.

其实他右脑边的同源也有同样的表现。

This is an area thought to be involved in expressive communication.

这个区域被认为是有关于表达和交流的。

音乐是语言的想法，

This whole notion that music is a language --

说到底大概是具有神经学基础的，

maybe there's a neurologic basis to it after all,

and we can see it when two musicians are having a musical conversation.

我们可以通过两个音乐人的音乐交流看到这结论。

So we've done this on eight subjects now,

我们已经对8个对象做了类似的实验，

and we're getting all the data together,

我们收集了所有的数据。

hopefully we'll have something to say about it meaningfully.

希望我们可以能从中得出一些有意义的结论。

当我们说到即兴和语言时，我们还会想到什么呢？

Now when I think about improvisation and the language, what's next?

说唱，当然， 说唱

Rap, of course, rap -- freestyle.

自由式说唱。

I've always been fascinated by freestyle.

我一直感到自由式说唱的形势很奇妙。

让我们在这里放一段录像。

And let's play this video.

CL: So there's a lot of analogy

CL: 所以自由式说唱和爵士乐之间

between what takes place in freestyle rap and jazz.

有很大的相似之处。

There are a lot of correlates between the two forms of music,

事实上，我觉得在不同的时代，这两种音乐有很多相关的地方

。

I think, in different time periods, in lot of ways,

在很多方面， 说唱实现了很多爵士曾经

rap serves the same social function that jazz used to serve.

担当的社会功能。

所以我们该怎样科学地研究说唱呢？

So how do you study rap scientifically?

我同事觉得我很疯狂，

And my colleagues think I'm crazy, but I think it's very viable.

但是我觉得这是可行的。

This is what you do:

这是你要做的：你请一个自由说唱的艺术家来

You have a freestyle artist come and memorize a rap

记住你为他们写好的说唱词，

that you write for them,

他们以前从来没听说过这种说唱词，

that they've never heard before, and then you have them freestyle.

然后你让他们自由发挥。

So I told my lab members that I would rap for TED,

我告诉我实验室成员说我会在TED讲台说唱，

他们说：“不会吧，你不会真正说唱吧。”

and they said, "No, you won't."

然后我想--

And then I thought --

(Laughter)

(掌声)

(Applause)

这说唱词就在

But here's the thing.

With this big screen, you can all rap with me. OK?

So what we had them do

所以我们让他们做的是

请他们记住左下角的声音记号。

这是控制的条件。这是他们记住的说唱。

Climb is sublime when I'm on the mic

♫ 当我即兴说唱时，我就如同攀登上了高峰一样兴奋Climb is sublime when I'm on the mic ♫

Spittin' rhymes that'll hit you like a lightning strike

♫ 这押韵的即兴表演就如同你被雷击一样Spittin' rhymes that'll hit you like a lightning strike ♫

♫ 我在这永恒追寻中寻求真理I search for the truth in this eternal quest ♫

Computer: Search.

I search for the truth in this eternal quest

♫ 我的激情可不等同于我的时尚，大家可能看出我不怎么打扮I'm passing on fashion; you can see how I'm dressed ♫

I'm passing on fashion; you can see how I'm dressed

CL:好的， 就在这里结束吧。你们看见他的大脑发生了什么呢？

CL: I'm going to stop that there; so what do we see in his brain?

这其实是四个说唱家的大脑记录。

This is four rappers' brains.

And we do see language areas lighting up,

我们看见了什么？我们看见了语言部分很活跃，

but then, eyes closed --

但是当他们闭了眼睛，

when you are freestyling vs. memorizing,

自由式发挥而不是单纯记忆时，

you've got major visual areas lighting up.

你看见视觉区域也活跃起来。

You've got major cerebellar activity, which is involved in motor coordination.

你看见大量协调运动的小脑活动。

如果将有创造性的活动和单纯记忆的活动来比较

You have heightened brain activity when you're doing a comparable task,

大脑活动在做创造性活动时更为活跃。

when that one task is creative and the other task is memorized.

It's very preliminary, but I think it's kind of cool.

这还是很初步的研究， 但是我觉得很酷。

总之，我们还有很多问题可以引申。

To conclude, we've got a lot of questions to ask,

and like I said, we'll ask questions here, not answer them.

正如我说的， 我们到这里来是提出问题的， 而不是回答问题的。

But we want to get at the root of what is creative genius neurologically,

但是我们想从神经学的角度来了解创造天才的真相。

我认为， 用这些手法，我们跟目标更接近了。

and I think, with these methods, we're getting close.

And I think, hopefully in the next 10, 20 years,

我希望在今后的10，20年间，

你会看见真正有意义的研究，

you'll see real, meaningful studies

它是说科学要追赶上艺术，

that say science has to catch up to art,

and maybe we're starting now to get there.

也许我们可以从现在开始追赶这个目标。

Thank you for your time, I appreciate it.

谢谢你们费时听我的演讲，我很感激。
