And the fundamental idea is you want to plan your movements so as to minimize the negative consequence of the noise.
話說回來，我們的基本思路是要找到一種動作方式，能夠把雜音帶來的負(fù)面影響降到最低。
And one intuition to get is actually the amount of noise or variability I show here gets bigger as the force gets bigger.
并且我們憑直覺就知道我在這里展示的雜音，或者說可變性隨力的大小的增加而增加。
So you want to avoid big forces as one principle.
所以我們的原則之一就是避免施加太大的力。
So we've shown that using this, we can explain a huge amount of data -- that exactly people are going about their lives planning movements so as to minimize negative consequences of noise.
用這個原則，我們就能解釋很多得到的數(shù)據(jù)--那就是人們在生活中有意安排動作方式來把雜音帶來的負(fù)面影響降到最低。
So I hope I've convinced you the brain is there and evolved to control movement.
現(xiàn)在，我想我已經(jīng)讓大家相信大腦之所以存在是為了控制動作。
And it's an intellectual challenge to understand how we do that.
而且了解怎樣做到這點(diǎn)是需要費(fèi)一番腦筋的。
But it's also relevant for disease and rehabilitation.
不過同樣具有相關(guān)價值的是在疾病和康復(fù)方面。
There are many diseases which effect movement.
有很多病癥有對動作產(chǎn)生影響。
And hopefully if we understand how we control movement, we can apply that to robotic technology.
所以如果有朝一日掌握了人類控制動作的機(jī)制，我們就可以用到機(jī)器人技術(shù)中去。
And finally, I want to remind you, when you see animals do what look like very simple tasks,
最后我要提醒大家，當(dāng)你們看見動物做些看似非常簡單的動作的時候，
the actual complexity of what is going on inside their brain is really quite dramatic.
它們運(yùn)行在大腦內(nèi)部的真正復(fù)雜度其實(shí)是相當(dāng)令人嘆為觀止的。
Thank you very much.
謝謝大家。
